The Best Travel Plug Adapter

By Geoffrey Morrison

If you want to use electronic devices in a different country, you’ll probably need a travel plug adapter. After spending more than 30 hours researching and testing 14 options, we found the Epicka Universal Travel Adapter to be the best one. It fits four types of outlets, and it has more USB ports than any of its competitors, so it can can charge more devices at higher speeds.

Everything we recommend

Epicka Universal Travel Adapter

Best universal travel adapter.

With four plugs that will work in most countries, plus faster-charging USB ports (and more of them) than its competitors, this adapter is the best all-around choice.

Buying Options

Ceptics International Worldwide Travel Plug Adapter 5 Piece Set

The best plug adapter.

Individually, these tiny plug adapters are smaller, lighter, and cheaper than any universal travel adapter. To juice up multiple devices, though, you’d need a separate multiport charger too.

Ceptics Plug Adapter Set

Heavier, but sturdier.

The plugs in this set of five are bigger and heavier than our top pick for plug adapters, but more solidly built.

In a sea of almost-identical travel adapters, the Epicka Universal Travel Adapter stands out, combining the best of the features we were looking for. It contains the three most common international plugs and a US-style plug, which should cover you in the majority of countries around the world. It has the most USB ports—four of the standard USB-A and one USB-C—of any universal adapter we tested, and it could charge more of our devices faster. A replaceable fuse and an included spare should take the brunt of any accidental, unfortunate, or shockingly bad connections. The Epicka is fairly compact and well built, and it even comes with a nylon case.

However, no universal travel adapter is truly universal, and they’re all a lot bulkier and more expensive than simple plug adapters. If you want the smallest adapter possible, or if you’re going someplace where a universal adapter won’t work (more on that in a minute), then a plug adapter could be what you need.

The Ceptics tiny plug adapters are barely larger than the prongs they convert. Small, simple, and cheap, they’re perfect for someone who wants to carry only the adapter they’ll need and who already has a multiport USB wall charger they like. Like our universal adapter picks, this set contains the three most common international plugs and the US plug. However, it also includes a somewhat rarer plug used in some European countries that has two thick, cylindrical prongs. This means that the Ceptics will likely cover you in even more places—as long as you pack the appropriate plug adapter.

These plug adapters are bigger than our top pick for plug adapters, but this means they offer a larger surface for chargers to brace against, which makes them more stable and less likely to fall off the wall. (We’ll call these “ Ceptics White ” to minimize confusion and set them apart from our “Ceptics Black” top pick.) While you can purchase these as a five-pack, which contains basically the same assortment of plugs as the Ceptics Black set, the company also sells, in this same model line, three-packs for nearly a dozen specific regions. So if you’re headed to a country not covered by the so-called universal travel adapters (for example, Brazil , India , Israel , or South Africa ), or if you want to purchase multiple adapters for your gear, there’s probably an option available here.

A note up here, which we’ll discuss in detail below: All of these are adapters only . They do not convert voltage. The majority of your electronic devices only need adapters—the voltage converter is built into the charger itself. (If the device charges via USB, just about any USB port will suffice, though different ports may provide different charging speeds.) Check out Do you need a voltage converter? if you’re curious about these aspects.

The research

Why you should trust us, who should get this, how we picked, how we tested, our pick: epicka universal travel adapter, flaws but not dealbreakers, our pick: ceptics international worldwide travel plug adapter 5 piece set, runner-up: ceptics adapter plug set for worldwide international travel use, do you need a voltage converter, the competition.

In addition to my work here at Wirecutter, I also write about tech and travel for CNET, Forbes, and Wirecutter’s parent company, The New York Times . Perhaps more relevant to this guide, I usually spend a good chunk of each year (global pandemics aside) as a digital nomad, living months at a time in different countries all over the world. My current country count is 50, spread across six continents, and since I travel with a lot of electronics gear for work, being able to plug in is obviously crucial.

I’ve owned and used many different types of universal-style travel adapters, and several different companies’ worth of plug adapters, plus I’ve talked with countless travelers about what they like … or, more important, what they hate. We also got some advice from Wirecutter's Mark Smirniotis, who used to oversee our power devices section.

Do you travel? Are you going to travel sometime in the (near or far) future? Do you want to be able to charge or use electronic devices in a different country? If so, you’re probably going to need a travel plug adapter. There’s a variety of different outlet types around the world, not to mention different voltages and frequencies, so you can’t expect your phone charger to just plug in and work wherever you’re headed. Sure, Canada, Mexico, Japan, and many other countries use the same small pair of prongs as the US, but places like continental Europe, the UK, Australia, India, Russia, and pretty much everywhere else do not.

You have two main choices when it comes to travel plug adapters: the universal-style travel adapters (that’s one device with multiple sets of prongs that you extend and retract) and smaller, individual plug adapters that usually come in sets. Both have pros and cons.

Should you get a universal travel adapter or a simple plug adapter?

Universal travel adapters are for the person who wants one handy adapter that will work in just about every country. You can keep it next to your passport and toss it in your luggage when you’re packing. The ones we considered have USB ports, so you don’t need to worry about bringing a separate charger for anything that charges via USB (think  phones  and noise-cancelling headphones ). However, these are bulky, they have parts that can break, and even the best will take longer to charge your phone or tablet than will a good USB wall charger .

The alternative is small and simple plug adapters. These attach to the prongs of your current USB charger (whether it’s a multiport one or the charger that came with your device) to allow them to fit into a foreign outlet. These can work because nearly every modern charger can adjust to the available voltage in pretty much every country, as long as you can adapt the prongs to fit in the outlet. (More on this in Do you need a voltage converter? ) These are great for people who already have a multiport USB charger they like and don’t want to deal with the additional bulk of a universal travel adapter. Also, these are necessary if you’re traveling to a country that has outlets incompatible with any of the four types included in a universal adapter (which, as that sentence reveals, aren’t actually universal).

The choice between universal travel adapters and individual plug adapters ultimately comes down to personal preference. Both types work, and different people will like or dislike each. If you’re not sure which will be best for you, read each section here closely.

Here’s the big caveat: If you’re planning on bringing something with you that has a motor, a heating element, or a single power cord that leads directly from the plug to the device (i.e. there’s no power brick or wall wart ), it almost certainly won’t work with a travel plug adapter. Most people will only need one of the adapter choices we recommend, but very occasionally there’s a piece of gear that needs a voltage converter. For more on that topic, also check out the voltage converters section below.

Where in the world will your travel plug adapter work?

All universal travel adapters have four different sets of prongs, which cover most countries most Americans tend to travel to. First is the big, wide-blade UK-style plug (often designated "Type G”) . This will work in places like the UK, obviously, and also Ireland, Hong Kong, and some other parts of Asia and the Middle East.

Next is the round Europe-style plug, aka the Europlug (Type C) . However, this is where we run into complications. This plug should work in most of Europe—it was designed, in fact, to fit into a wide range of European outlet types. For instance, parts of Italy, Switzerland, and Denmark each use different plugs from one another. Should this double-round one work in those locations? Yes. Will it? Hard to say. I’ve stayed in places where my Europlug didn’t work, yet it did in the hostel before and the hotel after—all within the same small region of a country. With any luck, if this happens to you, the place you’re staying will have a power strip that will let you plug in, though there’s no guarantee of that.

Third is the angled small-blade style (Type I) found in Australia, New Zealand, Fiji and other parts of Oceania, and a few other areas. Some universal adapters have one set of blades for this and the US style—you just manually rotate the blades into the correct position depending on where you are. In our testing, we had no trouble getting them to work.

The last, the small US-style blades (Type A or B) , mean you could use our picks to visit the US and other countries that have the same plugs—if, that is, you’re reading this from outside the US.

What are the places not covered by these four styles? Some parts of Brazil, South Africa, India, and more. I’ve stayed in parts of Italy, for example, that should have Europlugs but only had something called Type L . I’ve stayed in houses in Brazil that had Type N , but the Europlug fit enough to work. In others, it wouldn’t.

To find out which plugs you might need while traveling, refer to the excellent Wikipedia article called Mains electricity by country that shows pictures of (almost) all the possible plugs and outlets, along with a list of the world’s countries and (almost all of) the style or styles they use. This is invaluable information to check before you leave. If multiple plug types are listed for a specific country and you’re staying in an older building, you should probably assume its outlets will require whatever plug isn’t on a universal travel adapter, since these only have the most common, newer varieties of plugs.

Which brings us to perhaps the most important fact: Getting your gear to work in different countries isn’t quite as simple as it should be, and there’s no single solution that’s guaranteed to work for everyone. Our picks should work for you, but you may have some random piece of equipment, or be traveling to some country, for which our “good for most” picks just won’t work. (Case in point: One Wirecutter editor visited Iceland recently. The house she stayed in had outlets unlike anything on Wikipedia’s chart, and the plug adapters she’d used elsewhere in Reykjavik didn’t fit at all. It turns out the mystery sockets belonged to an obscure Italian system from the 1960s that was popular in Iceland for a time. Luckily, the hosts had power strips in the house that her adapters fit into.) We’ll try to mention such potential caveats when we can, but the world is a big place, and when it comes to electricity and wall outlets, there’s a lot of variation. That’s important to keep in mind.

There are approximately 70 billion universal travel plug adapters on the Web. However, after spending 20 hours staring at them, I found there’s only about a dozen basic designs—and countless “companies” selling them. Among those dozen or so actually different products, I saw a few distinctions that helped narrow the field. Since most options had four USB ports, that seemed like a reasonable minimum to require. Their maximum power output, rated in amps, became a determining factor in our rankings. The higher the maximum output, the faster the port will charge your gear.

Some plugs came with a replaceable fuse, which seemed like a good idea, and a few included a replacement for said fuse, which seemed even better. This way, if either you plug the adapter into a sketchy outlet or a roommate at the hostel uses your adapter to plug in their completely necessary portable arc welder, the fuse will go, not your adapter. Then it’s just a matter of swapping in the included spare fuse and you’re good to go.

These fuses have a maximum power rating, and therefore the adapters have a maximum wattage rating. However, you shouldn’t be connecting anything with a high enough power draw to trip these fuses. Check out Do you need a voltage converter? for more information. The short version is that recharging portable electronic devices is fine, but powering anything that has a motor or heats up is not. Nearly every appliance or device has its power draw written on it somewhere , so worst case, you can compare that to what’s listed on the adapter. And so you don’t have to look it up, volts × amps = watts.

The other option we considered and tested is individual plug adapters. These small adapters attach to the prongs of your current charger so they’ll plug into a foreign outlet. In deciding which of these to test, we judged by size and available plug-type options. As you’ll see with our two picks, one is exceptionally small, and the other offers sturdier plugs that are available in a range of plug types that’s wide enough to cover you no matter where in the world you’re headed.

The universal travel adapters are far more similar to one another than they are different. However, getting in a dozen and playing with them for a while revealed that some felt better put together than others. After spending several minutes with each one, forcefully extending the various plugs, slamming them back in, and just being fairly rough with them, I found it easy to tell which felt like they’d last a few trips, and which wouldn’t. None felt like you’d own them for a lifetime. Since none are expensive, though, this didn’t seem like a major issue.

All had a US-style plug, so I tested each one in several outlets around my house—some new, some old. I didn’t find much difference in how they fit and worked. I connected several chargers and plugs to the output side of each adapter as well. Again, not much difference. Last, I checked how bright the LED on each was, since a too-bright LED keeping me awake has been a pet peeve of mine for years. Many USB chargers have LEDs bright enough to practically read from; I eliminated any universal adapter that had this problem.

For the plug adapters, I tried plugging in several devices, as well as inserting them into outlets around my house. I checked how tight the connections were and how they felt overall. Would they fall apart with simple use or perhaps hold up to being tossed around in bags for a few weeks or months?

In reality, the testing for all the adapter types didn’t reveal much variation in terms of performance. These are all remarkably similar products. How they felt to use and their different features played a far bigger role in establishing our final picks.

While all the universal travel adapters we tested included the same three types of plugs (plus the familiar US-style one), they differed in how many USB ports each had and how quickly they could charge—and that’s where the Epicka Universal Travel Adapter excelled. It has five USB ports: four of the standard USB-A size and one of the newer USB-C. (You may not have a USB-C device at the moment, but you likely will in the future.) These will let you charge, say, three phones, two tablets, and—via the adapter’s main plug—a camera battery that has its own wall charger, all at once.

In addition, and just as important, is the maximum power output: 5.6 amps. This was the highest of all the adapters we considered, which means you can charge more of your devices at higher speeds before hitting the max output.

Keep in mind that the maximum output per USB-A port is 2.4 amps, the max on the USB-C port is 3 amps, and if you’re using all five ports you won’t be able to charge every connected device at full speed—it’ll only give you that 5.6 amp output in total . The output is still far lower than what you can get from a decent USB charger combined with our pick for a simple plug adapter (more on that in the plug adapter section , below), but it’s significantly better than most universal travel adapters, which often max out under 3 amps total.

The Epicka has three sliders on one side, with a button on the other to lock/unlock your chosen plug in place. This arrangement feels more secure than the semi-locking or slide-locking system that some other universals use. However, this is plastic-on-plastic, so don’t expect a tank. As these things go, the Epicka feels sturdy. The US and Australia share a pair of prongs—you twist the prongs manually to set them up for an angled Australia-style outlet.

The four regular USB plugs are all on one side, which is tidier than the “flailing gibbon” look of some other universal adapters.

The above details were what put the Epicka at the top of our list, but the adapter has a few other features that are the cherry on top, so to speak. For instance, it comes with a small nylon case and a USB cable with a split end, so it works with either Micro-USB or Lightning devices. While the adapter has an LED to show you it’s working, the glow isn’t so bright as to be a distraction at night.

One last note. There are multiple Epicka universal adapters, and even Epicka can’t keep the names straight. We’ve seen this one called, variously, Universal Travel Adapter, International Travel Adapter, Travel Adapter-2, Universal USB Travel Power Adapter (2018), and even Universal Travel Adapter One Worldwide International Wall Charger AC Plug Adaptor with 5.6A Smart Power 3.0A USB Type-C for USA EU UK AUS Cell Phone Tablet Laptop (Grey). Best to follow the link above. Also, you may find another company selling a twin of this. The Epicka has the most reviews and offers free shipping with Prime. The other options we saw have few or no reviews, or charge outrageous shipping costs.

As with all of these adapters, I wouldn’t expect the Epicka to last forever. Given its locking design and case, it’s probably going to last longer than many others, but all of these are almost entirely inexpensive plastic devices. Just something to keep in mind.

While the prongs themselves felt secure, and being able to lock them into place was nice, it’s entirely possible that the size and weight of the adapter, plus whatever you’ve plugged into it, could pull it out of an outlet. That is, unfortunately, a risk with every universal adapter.

Another risk with any universal adapter—as we mentioned above—is that it’s not going to work where you’re headed. Epicka claims it will work in 150 countries, but there are more than 200 countries (the exact number is harder to pin down than you might realize) . And even in each of those 150 countries, there’s no guarantee that the adapter will work in every outlet in every building. Plug adapters are a somewhat safer bet to work specifically where you’re going, but they have their own downsides, which we’ll discuss below.

Also, while the Epicka is a little smaller than some of the others we tested, all universal adapters are much bulkier than plug adapters. As someone who has spent most of the past several years traveling, I feel plug adapters are far easier and less annoying to deal with. This is largely why we have two recommendations for that category.

The Ceptics Plug Adapter set combines everything we were looking for in plug adapters: small size, solid build quality, and—well, small size is really the thing here. Each adapter is no larger than it needs to be to fit over the American-style prongs of your charger. The plastic feels solid and not flimsy. Each adapter has the region or countries it should be used in written on the side. The five plugs in the set are the same four as you’ll find on the universal adapters recommended above, plus the thicker, round European-style prongs used in parts of France, parts of Asia, and elsewhere.

Though the set comes with a small case, you probably wouldn’t be traveling with the entire set very often. Instead, you’d pack just the specific adapter or adapters you’d be using on each trip. These are for the person who wants to travel as light and as simply as possible. I myself, and my friends who travel frequently, swear by these small, inexpensive adapters. Also, if you have a USB multiport charger you like or a charger that’s especially fast, you can use that charger with just a tiny, almost weightless plug at the end.

However, plug adapters aren’t for everyone, and that’s why they’re not our main pick. For one thing, if you don’t already own a multiport USB wall charger, you’ll still have to get one if you don’t want to carry a charger for each device. Also, depending on what you’re connecting with these plug adapters, your charger or device could wobble and maybe fall out. The connections inside are solid enough that this shouldn’t happen, but it’s possible. Our universal-adapter picks, as well as the other Ceptics set we discuss below, have a larger “face” for your charger to brace against—more like that of a traditional outlet—so there’s less chance of gravity having its way with your gear.

Being small and inexpensive, plug adapters are not built for high-power, high-wattage items, though hopefully we’ve persuaded you to leave those at home . If you’re charging a battery, you should be fine. If you’re running a motor, probably not. Laptops, yes; mini-fridges, no.

Last, these things being so small, you could easily lose them in your bag or leave them behind in an outlet somewhere, if you’re the type of person who loses things. (That’s why I usually keep mine connected to my charger.)

For a hardcore traveler like me, these are my pick. They’re cheap, light, and small, and they work.

Though made by the same company as the Ceptics International Worldwide Travel Plug Adapter 5 Piece Set—and bearing a confusingly similar name—the plug adapters in the Ceptics Adapter Plug Set for Worldwide International Travel Use are, as you can see, a completely different design. They’re much larger than the other Ceptics (let’s call the previous set Ceptics Black and this one Ceptics White for simplicity). Nonetheless, they’re each smaller than a universal adapter, and they have one key benefit over our top plug-adapter pick: You can purchase them in multipacks for individual regions, including regions beyond those covered by the Ceptics Black set.

The Ceptics White are small, but not as small as the Ceptics Black. That extra size does offer one benefit, however: These adapters have more of a face on the output side, so there’s more surface for your charger to lean against. This means your charger is less likely to fall out. Again, neither set of plugs we tested had loose connections, but this is always a risk, as chargers vary. One other difference: In place of the two-pronged US plug we saw (type A) in our other picks, this set includes the three-pronged grounded version .

The real benefit to the Ceptics Whites, however, is not their physical characteristics. This range is one of your only options if you want to buy a plug adapter for a specific region or country. Headed to India or South Africa ? A universal adapter probably won’t work, but you can get a three-pack of Ceptics that will. You can also buy the offset three-prong and in-line three-prong for Switzerland and Italy, respectively, as well as plugs for Israel and Brazil , both the thin and the thick European plugs, and of course, Australia and UK versions too. They cost less than $10 per set. Any of those links will bring you to a page that lets you choose among plugs for different regions—definitely verify at checkout that you’ve picked the correct ones!

These adapters are ideal for someone headed to a country not covered by a universal adapter, or who has multiple chargers they want to plug in while traveling. They’re not quite as compact as the Ceptics Black adapters, but for most people, this difference in size won’t be an issue. I’ve traveled with these Ceptics plugs for many years, and they show no signs of wear.

Every adapter you see in this guide merely sends the current from the wall directly to whatever you plug into it. These are not voltage converters. Which is to say, if you’re in the UK, whatever you plug into the front of the adapter is going to get the UK’s 220 volts/50 hertz electricity, not the 120 volt/60 hertz that you’d get in the US. Travel plug adapters don’t convert the voltage; they only convert the plug . (Our universal picks do convert the local current to USB voltage, but only for the USB ports.)

However, for the vast majority of people, this is all you need. It’s exceptionally rare that anyone would need a voltage converter anymore. This is because most so-called wall warts, like on your phone charger or your camera’s battery charger, will convert the wall voltage into what it needs automatically.

Take a look at your charger. Somewhere, it should say “100–220V 50/60Hz.” This means it can accept anything between 100 V and 220 V, which covers domestic electricity pretty much everywhere, and either 50 Hz or 60 Hz, which again covers everything. If your charger doesn’t say this, it might not work with a travel adapter. If it only says "120V–60Hz," it will almost certainly not work—or not work correctly—with a travel adapter.

But here’s the other reason we don’t recommend buying a voltage converter: Your device might not work even with one. Anything with a motor (like hair dryers), anything with a heating element (like a clothing iron or a curling iron), or anything with a plug that goes directly to the device (as in no wall wart), probably won’t work in another country regardless of what kind of converter or adapter you bring . The good news is, pretty much every hotel, hostel, and Airbnb will have a hair dryer you can borrow. This is one of those times where we can’t cover everything you might want to bring, but for the vast majority of you, you don’t need a voltage converter. Either it’s not necessary, or the device that needs one won’t work anyway. Worst case, if it’s something cheap and you really need it—a hot pot or an electric kettle, say—consider buying one at your destination.

One occasional exception is electric razors. These often fall into the “single cable, no wall wart, has a motor” category. Which is to say, they probably won’t work without a voltage converter. (Again, check the fine print near the plug or on the device itself.) Many hotels have a shaver plug in the bathroom , with a US-style outlet and US-style 110 volt-or-so voltage. However, not every hotel will have these, and they’re very rare in hostels and Airbnbs. If you need one, best to call ahead and see if your hotel has them. Or use disposables on your trip.

It’s worth noting again for clarity, USB is USB, so if you’re just plugging in a USB cable , unless something is horribly wrong, one USB port’s voltage is the same as any other USB port’s voltage. How fast that port will charge your gear will vary (that’s related to amperage), but unless the charger is faulty, a USB port shouldn’t damage your gear.

We considered many more adapters than those listed here. However, the majority of travel adapters available boil down to just a dozen or so designs sold by myriad companies. We’ve listed two representatives of each of the most common designs, but in most cases, many more exist. Chances are, if it looks similar and has similar specs, it’s probably the same inside.

Universal travel adapters

Askali, Unidapt , others: Only 3.4 amps maximum output, which means it’ll take longer to charge all of your devices.

Bluegogo  (currently unavailable): Only two USB and slower-charging than our picks.

Bonaker: Formerly our runner-up pick, this travel adapter had the usual mix of four plug types to cover you in most countries, but its four USB-A ports were slower than our top pick’s, and it had no USB-C port at all. It’s also since disappeared from Amazon.

Bonazza , Urbo , others: Feels flimsy, even compared with others here. Two-piece design is more cumbersome than helpful. Only 3.4 amps maximum output.

Ceptics Travel Power Strip : The Travel Power Strip combines the interchangeable-plug aspect of the Ceptics Plug Adapter Set with a two-outlet power strip and short extension cord. It also has USB-A and USB-C outputs. If you have multiple non-USB items you want to charge at once—a laptop and a camera charger, for instance—this is a good option. But we think most travelers will prefer the more portable brick design of our picks over this power strip.

Conair Travel Smart : It has only one USB port, with a maximum of 1 amp, but with three outlets, it’s one of the few travel adapters that lets you plug in multiple non-USB devices.

Monoprice Compact Cube Universal Travel Adapter : I own one of these, and it’s fine, but if you’re going the universal route, our picks have USB charging for just a few dollars more. If you don’t need USB charging, our plug-adapter picks are probably better choices. Insten is a similar product but with, apparently, surge suppression built in. But as there’s no way to change the fuse, this is likely one-and-done if you plug in something too powerful.

Mu One (currently unavailable): The Mu offered a much higher power output than other travel adapters: 45 watts, enough to quickly charge even a big-battery device such as a MacBook Air. However, after trying and failing to launch a Mu Two in 2020, the company went out of business. The name and remaining assets were bought by a company called Discovery Club, which seems to be selling off the inventory.

Ougrand (green) : Same shape as the Unidapt, but with a USB-C in place of one of the regular USB connections; 3.4 amp max total.

Huanuo  (currently unavailable): A bit bulky, with three regular USB ports and one USB-C; 3.4 amps maximum.

WGGE , Jollyfit : Only 2.4 amps max, less than either of our picks.

Plug adapters

Bestek Grounded Universal Worldwide Plug : Likely made in the same factory as the Ceptics White plugs, the Bestek set looks the same and is roughly the same price. It offers a wide variety of plug types, but lacks the Type C Europlug that’s common in most adapter sets and usable across most of Europe. (The Europlug was invented to fit into a wide range of European outlet types.) If our Ceptics White pick is sold out, these will also work.

Lewis N. Clark Adapter Plug Kit  (currently unavailable): This kit looks fine, but it is more expensive and has one less plug compared with our Ceptics pick.

Insignia Global Travel Adapter Kit  (currently unavailable): The Insignia has a clever interlocking and compact design, akin to that of the old Flight 001 universal adapter (Flight 001, the specialty travel-gear retailer, is now no longer operating in the US), and the individual plugs feel solid. However, it is expensive compared with our picks, and it doesn’t offer anything that you couldn’t do with our picks just by connecting them end to end (if you wanted to).

Okay, so Japan operates on a 100V voltage and a frequency of either 50 or 60Hz, depending on the region . The eastern part of Japan, including Tokyo, uses 50Hz, while the western part, including Osaka and Kyoto, uses 60Hz. The country mainly uses Type A and Type B electrical sockets. Type A has two flat parallel pins, and Type B adds a grounding pin to the Type A outlet.

Travellers coming from Europe, the UK, the US and Australia, and other regions with a different standard voltage and plug type will find their devices well and truly incompatible with Japanese outlets!

For instance, European devices are typically rated for 220-240V, and Australian devices are rated for 230V. Using these devices in Japan without an adapter can result in poor performance, and damage to the device, or it may not work at all. Trust me, if you’ve just rocked up for the first day of your working holiday in Japan , this is NOT ideal!

Why You Need a Travel Adapter for Japan

Without a travel adapter for Japan, your devices will most probably not fit into wall sockets rendering them well and truly redundant. Even if your devices have the right shaped pins and do fit, this may not be safe and your electronics might be at risk of damage due to the voltage and plug type differences. It’s a pretty important bit of kit on any backpacking gear checklist !

A reliable travel adapter ensures that you can use and charge your devices safely, keeping you connected throughout your adventure. It’s a small investment that brings peace of mind and convenience, ensuring that your electronic devices are always ready when you need them.

Also, don’t forget to sort out your travel insurance for Japan for all that gear too!

With there being so many beautiful places to visit in Japan , you’ll want to make sure you have your camera and phone charged up and ready to go. So you’ve got to make sure you select the correct travel adapter.

When selecting a travel adapter, look for one that is compatible with both Japan’s Type A or B sockets.

Also, ensure that it is durable, has safety features like surge protection (you will pay extra for this, but it’s cheaper than buying a new phone…), and can handle the 100V voltage. 

There are various types of travel adapters available, including universal adapters that work in multiple regions and single-region adapters specific to Japan.

For backpackers and travellers alike looking to pack light, it’s essential to find a compact and lightweight adapter. These are easier to carry around and won’t add unnecessary weight to your luggage.

Personally, I generally use a World Travel Adapter that can be used anywhere on Earth. They are now widely available and really help when it comes to traveling light . Finding one that offers surge protection can however prove to be more challenging.

As I said above, there are loads of different travel adapters out there that will be at least semi-suitable for Japan. However, in our experience, these are the best Japan travel adapters;

Travel to Japan with confidence using the HAOZI International Travel Power Adapter.  Made for regular travellers, this adapter ensures your phones, iPads, and other devices stay charged no matter where you find yourself. With versatile plug options including EU, UK, AUS, and US, and a comprehensive range of socket adapters, this travel companion has got you covered worldwide.

The HAOZI travel adapter truly shines with its advanced charging port design. Unlike traditional adapters, it boasts 3 USB 3.0 charging ports plus a Type-C charging port, catering to a wide array of devices, including those that require a Type-C connection like the MacBook, Chromebook Pixel, and Samsung Galaxy S9.

The Universal, 5-in-1, Travel Adapter is an indispensable accessory for globetrotters, covering over 224 countries and catering to various plug types including Type C for regions like France, Germany, and Israel, Type G for the UK and Dubai, Type I for China and Australia, and Type A for the USA, Japan, and Canada. It is the perfect companion for worldwide travel or business trips, ensuring that you stay connected wherever you go.

Equipped with USB A and dual USB C ports, this international travel adapter offers versatile charging options, with the USB A ports supporting up to 2.4A and the USB C ports providing speedy charging up to 3A. It intelligently detects connected devices to optimize charging, making it ideal for a wide array of electronic devices from cell phones and tablets to cameras and laptops.

The Type A plug adapter provides a fairly seamless transition from 3-prong to 2-prong plugs in America and is widely compatible overseas in countries such as Japan, the Philippines, Canada, Mexico, China, Taiwan, Thailand and more.

It features two standard American AC sockets with a maximum power capacity of 2500W (250V, 10A), alongside two USB ports capable of delivering 2.4A of charging power. This adapter is smart enough to automatically identify connected charging equipment, allowing up to four devices to be charged simultaneously. It is ideal for a variety of electronic devices including mobile phones, laptops, cameras, and portable power supplies. Boom! (Well, hopefully not!)

However, it is crucial to note that this is not a voltage converter; it operates exclusively with devices compatible with 100V-250V voltage. When travelling abroad, ensure your devices are dual voltage and verify their compatibility before use.

This 2-prong adapter is an essential tool for both home and travel, facilitating the transition from a 3-prong to a 2-prong plug. It showcases global compatibility, functioning seamlessly in various countries including Japan, Canada, Mexico, China, and several countries across the Caribbean and South America.

This versatile tool serves as a 4-in-1 Japan Travel Adapter, equipped with 2 standard American AC sockets (supporting up to 2500W, 250V, 10A), and 2 USB ports capable of 2.4A charging. It can intelligently detect connected devices, optimizing charging for up to 4 devices simultaneously, The LED indicator is a thoughtful addition, keeping you informed about the power status.

Designed with stability in mind, this Japan travel adapter ensures a snug fit in the socket, providing extra support for larger, heavier plugs

This travel adaptor is expertly crafted for UK travellers heading to Japan and the Americas, ensuring a seamless connection for all British 3-pole earthed plugs with Japanese sockets. Perfect if you’re a Brit like me teaching English over in Japan .

With its sleek design, compact size, and lightweight nature, it guarantees ease of use and convenience for on-the-go packing. Despite its compact size, it doesn’t compromise on safety and meets the latest safety standards (BS 8546), ensuring a secure connection for all your small electrical devices. In essence, it combines safety, ease of use, and portability, making it a reliable travel companion for UK travellers exploring Japan and the Americas.

This universal adapter is robust, reliable, and comes with a built-in USB port. It’s compatible with Type A and B sockets, making it perfect for Japan.

Additional Tips and Considerations

Do consider purchasing your travel adapter before arriving in Japan. This will ensure that you have the time to find a properly suitable quality product and it will most likely also prove a lot cheaper than buying gear inside Japan which is a very expensive country .

That said, Japan is a tech economy and high-quality travel adapters are also available locally if you prefer to buy upon arrival.

To help better ensure the longevity of your Japan travel adapter, take proper care of it and store it in a safe place when not in use. Keep it dry, and try not to drop it too. But you already know that right?

Be wary of cheap knock-offs that can be damaging to your gear and potentially dangerous too. The best travel adapter for Japan will not be the cheapest and investing in a quality adapter ensures the safety of your devices.

Making the Most Out of Your Adapter

Beyond charging your devices, some travel adapters come with additional features like USB ports or built-in nightlights which are really very handy. Either way, it’s a must on any Japan packing list .

However, do take care to ensure safety by not overloading the adapter and always unplug it when not in use. To complement your travel adapter, consider adding other useful travel gadgets like a portable power pack and a universal power strip for charging multiple devices when you’re compiling your travel packing checklist .

A reliable travel adapter is a small yet crucial part of your travel gear when heading to Japan. It ensures that you can stay connected, keeps your devices safe, and adds heaps and heaps of convenience to your adventure. 

By choosing the right adapter, taking proper care of it, and being mindful of safety, you can make the most out of your trip. Prepare well, choose wisely, and enjoy every moment of your Japanese adventure with fully charged devices!

Best Overall

Jet off to more than 200 countries with this compact adapter in your luggage, and you can charge up all your gadgets. The classic slider design pushes out EU, UK, and US plugs, and you can rotate the pins for sockets in Australia or China. I appreciate how securely the plugs lock into place, and you must press a side button to retract them. You have a universal input socket, and Ceptics has included three USB-A ports on the bottom and two USB-C ports on the side. The USB-A ports can deliver a maximum charging rate of 15.5 watts, while the USB-C ports offer up to 18 watts (one PD and one QC 3.0).

The main problem is the lack of any grounding, which is meant to reduce the risk of an electrical shock if there's a fault, such as a loose wire inside a device with a metal case. ( This video explains grounding really well. ) Thankfully, there's overload protection with an 8-amp fuse, and it comes with a spare, but you should not use this adapter with any device that has a third metal ground pin on its plug.

Upgrade Pick

Zendure's all-in-one travel adapter is what I toss in my bag first for every trip. It has a boxy design with sliding toggles to switch between US, European, and British plugs. (It covers more than 200 countries.) There’s an auto-resetting fuse to protect your gadgets from power surges, and the Passport III has a 10-amp limit. The latest version also sports a funky, translucent design with a metallic finish (purple is best). Sadly, there's no grounding, so you shouldn't use this adapter with any device that has a third metal grounding pin on its plug.

There are four USB-C ports alongside a single USB-A port and an AC socket, so you can charge six devices simultaneously. Using gallium nitride technology, Zendure was able to increase the power output of the USB-C port to 65 watts, capable of fully charging a 13-inch MacBook Pro in under two hours. That means you can leave your laptop's charging brick behind (if it charges via USB-C). There’s support for the Power Delivery (PD) and Programmable Power Supply (PPS) standards (Samsung uses PPS in its flagship range), so it can fast-charge almost any phone or tablet. It’s expensive, but this travel adapter will satisfy even the most gadget-laden of travelers.

★ A Good Alternative : The OneWorld 65 ($69) sports a very similar design, the same 65-watt charging rate, and support for more than 200 countries. But it has three USB-C and two USB-A ports. It comes in white and has a 10-amp fuse with a replacement included. WIRED readers can also get a discount with the code OneWorld65_15%Off .

Budget Pick

With the capability to work in more than 150 countries, this affordable adapter from Epicka will do the job for most people. It has sliders you push to reveal the three most common international plugs—EU, UK, and US—and you can rotate the pins for sockets in Australia or China. This plug can recharge your power-hungry devices, like laptops and camera batteries, but there are four USB-A ports on the bottom and a 15-watt USB-C port on the side for phones, tablets, smartwatches, and Kindles. It’s not as well constructed as our other universal adapter picks, but it's much cheaper.

Once again, there’s no grounding here, so don’t plug devices with a third metal ground pin into this adapter, but there is an 8-amp fuse for safety, and it comes with a spare. It is also certified by RoHS, CE, and FCC.

Best Travel Adapter Set

Universal adapters don't always work properly everywhere, and most do not have any grounding. The cheaper and more reliable alternative is to buy individual adapters. This international set from Ceptics is our favorite. It includes five types to cover most of the globe, and they are properly grounded. If you’re visiting only a single destination, just pack the relevant type. None of these adapters have any kind of USB ports, so you will need to bring the respective charging adapter for your gadgets.

This set is especially good for Europe, because it includes Type C, E/F, and G adapters (more on this below), so you’re covered for any socket. Ceptics offers an even cheaper and smaller five-piece set, but we don’t recommend it. The adapters are flimsy, there’s no grounding, and the European plug's design doesn’t work well with the recessed sockets you will sometimes encounter.The drawback of plug adapters is that they’re easy to lose, but at least Ceptics includes a small bag for storage.

Extra Outlets

What I love about this sturdy, compact plug adapter is the lack of sliding pins or moving parts to worry about and that it stays put in the outlet. Offered in several versions (Type C, Type E/F, Type G), it enables you to charge up to six gadgets. I’ve been testing the Type G model in Scotland, and it plugs into a single outlet to give you three US outlets, a USB-C port, and two USB-A ports. The USB-C can put out up to 15 watts, and the USB-A ports are limited to 12 watts, not especially speedy but fine for overnight charging. The adapter is grounded and has various safety features.

On the downside, it can be tough to make use of all the outlets simultaneously as larger plugs, like the MacBook power adapter, tend to block one of the other US outlets. It does not offer surge protection, and the Type G adapter maxes out at 3,250 watts (250 volts, 13 amps), while the EU versions top out at 2,500 watts.

For Charging Everything

This kit includes multiple plug attachments that slide and lock into place to keep you powered across most of the world. It is much larger than the average adapter, but provides two grounded US AC outlets. There is also a built-in USB-C cable, two USB-A ports, and two USB-C ports. The USB-A ports and built-in USB-C cable offer a combined maximum charging rate of 15 watts. The PD USB-C ports go up to 20 watts each. The top charging rate for all of them simultaneously is 55 watts.

There is built-in surge protection, but this is not a voltage converter, so don’t go plugging in hair dryers or other electronics that are not dual voltage. While the two AC outlets are handy, they are close together, so the shape and size of some plugs can make it tricky to use both. But with the ability to charge up to seven devices, this kit is handy. We also like the original Ceptics World Travel Adapter Kit ($36) , though it lacks the two USB-C ports.

Fast Charging

With a familiar sliding pin design, this adapter also covers more than 200 countries. Taller and heavier than our top pick, this is OneAdaptr’s most powerful release to date, and it employs gallium nitride technology to deliver up to 100 watts. Aside from the universal AC outlet, you will find two USB-C ports and two USB-A ports on the bottom. Both USB-C ports offer 100-watt charging, and both USB-A ports are 18 watts, but 100 watts is the maximum in total, so when you plug in multiple devices, it divides between them.

Almost every charging standard you can think of is supported, including PD 3.0, QC 4+, FCP, SCP, AFC, PPS, and more, so there’s a good chance you can charge your phone at the fastest rate possible. There is no grounding, so don’t plug in any gadget with a third metal pin. But there is a 10-amp fuse with a spare included, and this adapter conforms to IEC 60884, CE, and FCC standards. If you want more power or feel you can make do with less, we also tested and liked the OneWorld135 ($109) and the OneWorld30 ($39) .

Note : We have tested OneAdaptr’s range extensively and found they work well, but the company has had issues fulfilling orders, and we are concerned about the volume of negative reviews online. The company assured us that it has recently taken steps to improve fulfilment and customer service, and we will continue to monitor the situation.

Safest Option

The OneWorld PD has sliding toggles on the side that cover the US/Canada, the UK, and Australia/China, and you can pop out a much smaller stand-alone European adapter. It promises to work in more than 150 countries. There are three USB-A ports on the bottom as well as a USB-C port that supports Power Delivery and Quick Charge 3.0 to deliver up to 18 watts. That's enough to fast-charge most phones and tablets, not so much a laptop. You can plug in your laptop's AC charger to speedily juice it back up, but that means carrying the heavy charging brick around.

What sets the AC plugs apart is that each one is earthed. Most universal travel adapters offer two-pin US plugs and make the third pin on the UK plug plastic, but the OneWorld PD provides fully grounded connections for every plug type to protect you from the risk of shock due to faulty wiring. It can handle up to 10 amps. Over-current protection automatically shuts down the power if there’s abnormal usage, and it resets via a button on the top. The rare British Standard 8546 compliance guarantees that the OneWorld PD has been fully tested and is one of the safest travel adapters you can buy. The downside? It's frequently out of stock.

Note : We have tested OneAdaptr's range extensively and found they work well, but the company has had issues fulfilling orders and we are concerned about the volume of negative reviews online. The company assured us that it has recently taken steps to improve fulfilment and customer service and we will continue to monitor the situation.

For Wireless Charging

A few of the best wireless chargers can be good choices for travel. This modular system from RapidX is compact and capable of wirelessly charging two phones at up to 10 watts each, which makes it a good option for couples or families. The beauty is that you can add or remove pods, and a single charging cable can power up to five. They snap together magnetically and pull apart for easy packing. You can also get additional phone pods ($15) , and there’s a version with a phone pod and an Apple Watch pod ($45) .

You get a 30-watt US power adapter and a 5-foot USB-C cable in the box, so you will still want a travel adapter to pair with this system. If you plan to add pods, you will want a more powerful adapter. (RapidX recommends 65 watts or above for three or more devices.)

For Apple Devices

This handy trio of chargers keeps your iPhone, Apple Watch, and AirPods ticking and folds neatly into a felt carrying case for travel. The magnetic pad in the center can charge your iPhone at the fastest 15-watt rate, the Apple Watch dock pops up for Nightstand mode (sadly no fast charging here), and there is a grooved spot for your AirPods. It is compact and lightweight, and charges all three devices from a single cable and outlet. A 30-watt US wall adapter and a short USB-C to USB-C cable are included, but you must pair this with a travel adapter. We recommend this Mophie charger for travelers in our guide to the  best Apple 3-in-1 wireless chargers .

International Plug Types and Universal Adapters

There are 15 plug types in use across the world. Type A and Type B are used in the US, Canada, Mexico, and Japan; Type C is common across Europe, South America, and Asia; Type E and Type F are found across Europe in places like Germany, Russia, and France; Type G is used in the United Kingdom, Ireland, and a handful of other places; and Type I is used in Australia, New Zealand, China, and Argentina. Universal adapters tend to cover all of these types.

Some countries are not usually covered by universal adapters, such as India ( Type D ), Israel ( Type H ), and South Africa ( Type M or N ). You'll need to buy specific plug adapters for those places. To avoid any surprises when you land, double-check what type you need before you travel.

If you're visiting just one destination, a basic plug adapter that caters to one plug type is all you need. For trips to multiple destinations or for frequent flyers, a universal travel adapter can prove more versatile. The universal adapters we recommend here have the bonus of including multiple USB ports for charging several mobile devices from a single outlet.

A Word on Voltage Converters

Voltage converters are big, heavy, and expensive, and they don’t always work, so it’s probably best not to buy one. The reason you might think you need one is that the AC sockets on all of our recommended travel adapters do not convert the voltage coming from the socket. This means plugging into a UK socket will deliver 220 volts at 50 hertz, which is very different from the 120 volts at 60 hertz you can expect in the US. Don't worry! Your gear won't get fried. You just need to make sure anything you plug into one of these universal travel adapters has something like this printed on it:

Input: 100–220V 50/60Hz .

That should include most modern gadgets. If your device or charger can’t handle a variable voltage, it’s probably best to leave it at home. Most places provide hair dryers , irons, and kettles, so there’s no need to take them with you. It's often cheaper to buy a set with the correct plug at your destination and save the luggage space and hassle.

Travel + Leisure / Alexander Huang

Travelers these days have all types of gear and gadgets that require power: cellphones, headphones, cameras, laptops, and even their toothbrushes. And, when venturing abroad, you’ll often find that not every hotel, airport lounge, or even public mode of transportation accommodates the U.S. plug, which means you likely need an adapter and/or converter for international trips. 

Our favorite adapters and converters are compact, work in multiple countries, have several ports including both USB and AC sockets, and, of course, power your essentials without frying them. As avid travelers, we tested an array of products on actual trips across the world and ranked them based on ease of use, effectiveness, and value to bring you the best picks for every scenario. Below, find our favorite easy-to-use adapters and converters for your next international journey.

Best Overall

Epicka universal travel adapter.

• Ease of Use 5 /5
• Effectiveness 4 /5

It’s able to charge six devices at once. 

This is not a converter, so you shouldn’t use it with high-power appliances like curling irons and hair dryers. 

Ready to use in more than 150 countries, this adapter from Epicka can charge six devices at the same time, as it comes with four USB-A ports, 1 USB-C port, and 1 AC socket. It works with all USB-enabled devices including iPhones and Androids, and can charge laptops, cameras, tablets, and power banks, too. It eliminates the need to purchase individual adapters for each trip, which makes it a great money-saving travel product . The adapter also has a built-in, double 8A fuse and safety shutters that keep children from trying to plug other items into the socket. The adapter comes in four different colors, and has a 1-year limited warranty. 

We love that it’s small and easy to pack, plus it’s simple to switch over to different prongs from country to country. The multiple USB ports are great for charging everything at once, and the adapter is super lightweight, so it isn’t adding much weight to your suitcase or carry-on either. We did find that the adapter was hard to fit in tight spots or use with older outlet styles in the UK and Hong Kong, but this didn’t happen often. 

The Details: 2.8 x 1.97 x 2.05 inches | 5.1 ounces | No converter | 6 ports | 1 AC, 4 USB-A, 1 USB-C | 240 volts

Travel + Leisure / Alexander Huang

Best for Apple Users

Apple travel adapter kit.

• Effectiveness 5 /5

It’s exclusively for Apple products so you can trust it with those devices.

It only works with Apple's block-type power adapters.

This kit made by Apple, for Apple products, includes seven AC plugs that work for iPhones, iPods, iPads, and Mac laptops in North America, Japan, China, the UK, Europe, Korea, Australia, Hong Kong, and Brazil. Each one lists the regions the plug is compatible with, making it easy to grab what you need quickly. However, you will need Apple's power adapter brick to serve as a base; these tips work with Apple’s USB-C power adapters, MagSafe and MagSafe 2 power adapters, and 10-watt and 12-watt USB power adapters that come with devices (or can be purchased separately in a range of wattages including 12 watts , 35 watts, and 67 watts ).

We love this set because it’s an Apple-certified product, so we know our devices are safe. The adapters are also built to last, as one of our testers used the adapters for 10 years before having to replace some of them. The only thing we wish they added onto this set is a carrying case to hold all the pieces for traveling. 

The Details: 5.3 x 5.3 x 1.9 inches | 11.2 ounces | No converter | 1 port | 100-240 volts (10W, 12W, 30W, and 35W)

Most Compact

Ceptics travel adapter plug for south africa & botswana.

It comes with USB and AC outlet charging abilities in a compact plug. 

USB ports are on the bottom, instead of the top of the adapter. 

If you’re traveling through South Africa, Botswana, or Namibia, this compact adapter will allow you to charge up to three devices at once. The AC outlet allows you to plug your U.S. device into a Type M socket for South Africa, allowing you to charge up for safari adventures and more.  It works with cell phones, laptops, smart watches, tablets, and more, and we especially like that it has the ability for two- and three-prong AC input, as well as USB ports for added versatility. The style of adapter is a block shape, so you can tuck it into your backpack, purse, or carry-on without compromising on much space, and you can also buy similar adapters for Europe , India, Germany, Hong Kong, Switzerland, Brazil, and more. 

The Details: 1 x 1 x 1 inches | 2.5 ounces | No Converter | 3 ports | 2 USB-A , 1 AC | 250 volts

Best for Families

Bestek travel adapter and voltage converter.

• Value 4.5 /5

You can power seven devices at one time. 

It’s bulkier than a lot of other adapters. 

With three AC outlets and four USB ports, you can charge up to seven devices at once on this charger, making it easy for the whole family to charge their phones, laptops, tables, and camera batteries. Three plug adapters are also included and work in more than 150 countries, meaning you can travel far and wide and, most likely, have the right adapter for what you need. We also love that this one is a converter, too, converting 220 volts to 110 volts for U.S. electronics but it’s still not recommended to use this device to power your hair dryer, curling iron, or straightener.

The adapter comes with overcurrent, overload, overheat, and short-circuit protections. We tested the adapter by charging a phone, battery pack, Apple watch, and Kindle all at once and found that all devices were nicely charged overnight with no issues. 

The Details: 7.4 x 6.8 x 1.8 inches | 1.15 pounds | Converter | 3 AC, 4 USB-A | 110-220 volts

Best Multipack

Ceptics european travel plug adapter.

• Ease of Use 3 /5

It’s easy to use.

You'll need to use a separate plug for each item you're charging.

For a super affordable multipack for one destination, this one from Ceptics is a great choice, as it comes with three identical Type C adapters that will work across Europe, the Middle East, and South America. It accepts North American two- and three-prong plugs, and has a simple straightforward design. It’s worth noting though that this set won’t work in England, Ireland, or Scotland, but there are other three packs available that will work in those countries, plus India, China, Hong Kong, Australia, and more. 

The Details: 3 x 2 x 1 inches | 3.2 ounces | No Converter | 3 AC outlets | 100-240 volts

Best for Europe

Jarvania european travel plug adapter.

It works in both the EU and the UK. 

It’s a bit bulky as the UK adapter is separate. 

American travelers to Europe will most likely need an adapter that can handle numerous countries, and this one from Jarvania is great because it can be used with EU and UK outlets. It’s compatible with Type C (which also fits into Type E, F, H, J, K, L, and N outlets) to work in Italy, Denmark, Switzerland, Spain, and France and more. It also comes with a separate Type G plug adapter that will also work in the UK, so you’re getting an extra adapter, too. The main adapter has three ports (one AC, two USB), so you can charge up to three devices at once — a perk for the modern traveler carrying a phone, laptop, camera, and more. 

The Details: 2.7 x 2.1 x 2.2 inches | 3.8 ounces | No Converter | 3 ports | 1 AC, 2 USB-A | 110-250 volts

Other Travel Adapters We Liked

Two adapters we tested couldn’t quite earn a spot on our list but had standout features that may meet the needs of some travelers. 

Tessan Type G Adapter : This adapter with two AC outlets plus two USB ports works in countries such as Scotland, Ireland, the UK, Hong Kong, UAE, Singapore, and various African countries. However, we found the AC outlets are too close together on the adapter to always be useful. 

Tessan Type E F Adapter : With five total ports (USB and AC) that work in numerous countries, this is a great adapter, but we think the two pack is a bit much, as one adapter already has five ports, meaning lots of travelers wouldn’t need a second adapter. This adapter is also wider than other adapters so it can take up more unnecessary space. 

The T+L team tested 12 different adapters and converters in various countries across the world. We noted what countries we were in while using the adapters or converters, and how easy it was to use each one. We also ranked them based on effectiveness, meaning how well they charged our devices, and value in terms of price versus performance. 

Tips for Buying Adapters and Converters

Research your destination.

Before leaving on your trip, be sure to check out what types of outlets are used in the countries you’re visiting, and buy adapters and converters accordingly. The last thing you’ll want is to accidentally fry your device while abroad. Some hotels provide USB ports inside hotel rooms, but it’s best to make sure they’re available before arriving empty-handed.

Consider a kit

If you’re visiting numerous countries and are in a rush, it’s sometimes easier to simply buy a kit with several adapters for multiple different destinations, which can save you money instead of buying numerous adapters. Lots of kits are small enough to tuck away in your bag or carry-on, so just be sure that you take along the ones you need.

Read the fine print

Always be sure to read the instructions that come with your adapter or converter, and be sure to pay attention to the power details. You may think a converter is safe for your styling tools or appliances when it's actually not, and you could fry your device, or blow a fuse, if the adapter doesn’t convert voltage.

An adapter is used when you need to plug a specific type of prong into a different socket. It allows you to plug your U.S.-style prong into an outlet in another country that uses a different type of plug. A converter is different in that it changes the voltage of an outlet to match the voltage of the item being plugged in. Some countries use 110/120 volts, while others use 220/240 volts. If you don’t use a converter, you could ruin your device, or even risk a fire.

If your destination has a different prong type than your outlets at home, then you’ll need an adapter. But if the voltage is different in the place you’re traveling than it is at home, you’ll need a converter to convert that voltage. Some products have dual voltage, which means the device can handle voltages from all over the world.

Most of Europe uses Type C plugs, which also fit into Type E, F, H, J, K, L, and N sockets that may replace Type C in places such as Denmark, Switzerland, and Italy. (England and the rest of the U.K. uses Type G.) Always double check exactly which one you’ll need before your departure.

Do I Need an Adapter in Japan? All You Need to Know

One of the most asked questions when preparing for a trip to Japan concerns what should you pack for Japan. I’ve seen lots of good answers, but I noticed that most of the time something was missing: the travel adapters. Of course, not all tourists will need one because Japanese plugs and sockets are similar to a few countries, but what about other countries, like the US or even European countries?

Tourists from the United States or Canada don’t need a plug adapter , but they need a 3-to-2 prong adapter and sometimes a frequency converter because Japan uses two frequencies (50Hz / 60Hz). Tourists from other countries will need a plug adapter and a voltage and frequency converter.

I’m guessing that all this might sound like a foreign language the first time you read it, but it is actually pretty simple. I’ll explain it to you in the next paragraphs, and I’ll give a few examples, so you can prepare the right adapter for your trip.

What Types of Plugs and Sockets are available in Japan?

First, let’s start by understanding which plugs and sockets are available in Japan.

In Japan, you will find type A plugs (which are ungrounded plugs with two flat parallel pins) and type B plugs (which have two flat parallel pins and a round grounding pin). These types of sockets (A and B) are also used in the United States and Canada, for example.

So does this mean that Americans and Canadians don’t need an adapter?

You probably won’t, but I would take at least a 3-to-2 prong adapter because if you arrive in Japan with equipment that uses a grounded plug, and you only have a type A socket available, you will have some problems plugging it. If you don’t bring to Japan equipment that uses a grounded plug, then you don’t need a 3-to-2 prong adapter.

Hey, check out these recommendations I have for you!

Before going any further, take a look at some of the recommendations I've handpicked for you. I think these are essential items you should have on your trip to Japan. You can check them out and buy them directly from Amazon.

If you don’t have one already or if you’re not sure what it is, you can check the 3-to-2-prong adapters easily on Amazon . It is inexpensive and small, and it can avoid this annoying problem once you get to Japan. I saw lots of people commenting that they had a hard time finding Type B sockets, so it’s really worth taking a 3-to-2 prong adapter.

Tourists from most countries other than the United States or Canada must have a plug adapter for their equipment. If you’re used to traveling far away, you probably have one already, but if not, you can find lots of plug adapters on Amazon with great reviews and low prices. Make sure you choose a universal adapter that you can use for other countries too. This way you will save money for your next trips worldwide, and it will avoid the inconvenience of having lots of different adapters.

Personally, I always have a universal travel adapter when I travel, it doesn’t convert voltage (which can be an issue for some appliances), but at least it allows me to plug any equipment. I bought this travel adapter from Amazon a few months ago, and it still works great.

Of course, you can also buy an adapter in Japan, but it will be more difficult to buy the right one if you don’t speak Japanese. By the way, if you buy things in Japan, you might want to read some useful information about tax-free items and which ones you can open/use while in Japan. I wrote an article explaining all the rules for tax-free items so that people can be prepared.

Do I Need a Voltage Converter in Japan?

Now that we have seen everything you need to know about the plugs’ shape in Japan, let’s move on to the next problem: voltage and frequency .

Even if you’re not an expert in electricity (don’t worry, I’m not an expert either), you should know that Japan’s voltage and frequency differ from most countries. Luckily, Japan’s voltage is not far from the one in use in the United States or Canada , and your appliances might work, but be warned, sensitive appliances may suffer if you plug them in directly .

The best thing to avoid any unnecessary risk is to use a voltage converter and a voltage adapter . Several travel adapters can do both.

So what’s the difference between a converter and an adapter?

A converter can step down your appliance power to be used with the Japanese voltage. This converter is needed for appliances that have a single voltage .

On the other hand, an adapter adapts the power to the right voltage . Adapters are needed for appliances with dual voltage . These appliances will have the following: INPUT: 100-240V, 50/60 Hz . This means that they can be used worldwide with an adapter.

I can’t stress enough how important this converter and adapter thing is to keep you safe (and your appliances) when trying to plug them while in Japan.

As I mentioned before, there are adapters you can buy that do both (adapter and converter). Some nice models on Amazon are not expensive and are compatible with lots of appliances. If you’re looking for small models that can fit everywhere, I would say that this travel adapter and converter on Amazon is what you need. But if you need to charge several appliances at the same time, a larger one might be a good choice (like this adapter a nd converter on Amazon ).

These recommendations are for American and Canadian tourists. For other countries, you’ll have to switch to the Amazon website that serves your country, but the links above will give an idea of what you should search for.

Here’s a table with some English-speaking countries’ voltage for reference. (At the end of this post there’s a link to check other countries in the world too.)

Another important thing you should know about Japan’s electricity is that they use dual frequency. Along with Korea and Liberia, Japan is one of the few countries using dual frequency . This means that Japan, Korea, and Liberia can use 50Hz and 60Hz when almost every other country chooses either 50Hz or 60Hz , but not both.

As a general rule, Eastern Japan (Tokyo, Yokohama, and other northern areas) uses 50Hz and Western Japan (Nagoya, Osaka, Kyoto, Hiroshima, and other southern areas) uses 60Hz .

Usually, frequency is not a big deal except for appliances like clocks, or appliances with motors where speed can be an issue . For instance, a clock operating at 50Hz will run faster on 60Hz and you will have a time problem. Luckily, most appliances are compatible with dual frequency. I checked some of mine and I only found appliances compatible with both frequencies. Make sure you check what’s in use in your own country before you travel.

Here’s a table with the frequency used in the countries we saw above .

I’m not going to list all the countries’ differences regarding voltage and frequency, but as promised, I’ll leave you a link to the International Electrotechnical Commission website which has a list with all the details (plug type, voltage, and frequency by country).

I tried my best to explain to you all these electrical differences in Japan (with some examples of the types of products that can help you), so you don’t have any unpleasant surprises during your travel, but make sure you do a little research by looking carefully at all your appliances before taking them to Japan.

By the way, lower-wattage appliances (0W – 25W), like electric toothbrushes or shavers for example, can’t be used even with a converter .

Travel Adaptor for Japan

Japan travel adaptors.

You will need to consider what to pack, to ensure you can use your personal electrical appliances safely whilst abroad. This normally includes the use of a  travel adaptor ,  which is a device that simply allows you to plug any UK electrical appliance into a foreign electrical socket. It is important to note that it does not convert the voltage or frequency.

What plug sockets are used in Japan?

For Japan there are two associated plug types, A and B. Plug type A is the plug which has two flat parallel pins and plug type B is the plug which has two flat parallel pins and a grounding pin. Japan operates on a 100V supply voltage and 50/60Hz.

Voltage converters and transformers

Electricity supplies worldwide can vary from anything between 100V and 240V. It can be extremely dangerous to use an electrical appliance that is rated at a voltage different from the supply.

As voltage can differ from country to country, you may need to use a voltage converter or transformer whilst in Japan. If the frequency is different, the normal operation of an electrical appliance may also be affected. For example, a 50Hz clock may run faster on a 60Hz electricity supply.  Most voltage converters and transformers come supplied with plug adaptors, so you may not need to buy a separate travel adaptor.

All converters and transformers will have a maximum power rating (AMPS or WATTS) so make sure that any appliance you intend to use does not exceed this rating.

Dual voltage rated appliance

You can determine whether you’ll need to use a converter or transformer, by looking at the appliance rating plate.

A dual voltage rated appliance will display for example ‘INPUT: 100-240V’ on the body of the appliance or its power supply. This means that you will not need a converter or transformer but just a travel adaptor, because Japan operates on a 100V supply voltage, which is within the 100-240V range that the dual voltage appliance operates on.

Single voltage rated appliances

In Japan the supply voltage is 100V. If the appliance or its power supply are not dual voltage rated, the single voltage appliance will have to be used alongside a voltage transformer or converter to allow the appliance to work safely and properly (unless the appliance operates at 100V).

Converters and transformers perform a similar function, but their applications differ. Converters are typically used with appliances that operate for a short duration (1-2hours), whilst most transformers can be used alongside appliances that operate continuously.

It’s important to understand that some travel adaptors are not suitable for any appliances that require an earth connection. These types of travel adaptors should only be used with double insulated equipment, which will be clearly marked with the symbol shown below.

We recommend you check your appliances before embarking on your journey, to understand the requirements in Japan.

The best travel adapters for 2022

Whether you’re a digital nomad who works on your laptop from a sandy foreign beach or a high-powered, all-business road warrior, you will need a travel adapter for your journeys abroad. Travel adapters let an electronic device from one country plug into an outlet from a far-off land.

Xcentz Universal Power Adapter

Fuse chicken universal, epicka universal travel adapter one, zendure passport go travel adapter, saunorch international travel adapter, bestek universal worldwide travel adapter set, mu portable international charger, evo global travel adapter.

In the U.S., outlets use a plug with at least two flat vertical prongs, whereas in the U.K. outlets call for a plug with a top vertical prong and two bottom horizontal ones. Note that an adapter may not convert electricity, but this is something you will likely need. That’s because different countries and regions use different voltage ranges — North American devices function with a lower electrical voltage (110/120V) than devices from most other locations on the planet (220/240V) — but all-in-one adapters can convert them to a single standard. Travel adapters can save you a serious headache — and a lot of money — on your journey. We’ve gathered some of the best multi-device travel adapters to keep you juiced up while on the move.

Of all the travel adapters on our list, this offers versatility and handy features in a compact package. If you’re traveling through many countries, this one adapter could meet all your needs. It covers 200 countries, including the United States, United Kingdom, Europe, Australia, Canada, and Japan. To switch between plug types, you press and slide one of the three buttons, each of which locks firmly in place, or you can pull out the compact European plug section. Plug your gadget into the other side and you’re all set. The Xcentz Universal Power Adapter includes three USB-A ports that support Qualcomm’s Quick Charge 3.0, and a USB-C port that supports Power Delivery up to 18W, so you can charge multiple devices at once. The clever feature is the adapter’s self-resetting fuse. Usually, when the fuse in your travel adapter blows, you have to replace it. This one will trip and block the overload, letting you can push the button on the side to reset it. The universal charger is rated at 10A and supports up to 2,300W of combined power, while the pop-out EU plug is 16A and goes up to 3,680W in total.

This clever device is the perfect travel adapter for keeping your smartphones and tablets charged up. There’s a slide-on plug section and it comes with plug attachments for the U.S., Europe, the U.K., and Australia. It has USB-C and USB-A ports and it can put out up to 18W. The USB-C port supports Power Delivery and the USB-A port supports Qualcomm’s Quick Charge 3.0 standard. But that’s not all, because the Fuse Chicken Universal also packs a 6,700mAh battery inside for topping up on the go — and it works as a Qi wireless charger.

The Epicka Universal Travel Adapter One is a serviceable choice for an all-in-one world travel adapter, covering more than 150 countries with U.S., EU, AU, and U.K. plugs. It features smart fast charging with four USB ports, one USB Type C, and one AC socket with the ability to high-speed charge six devices simultaneously. Its power maxes out at 880W at 110Vac and 1840W at 230Vac. It’s compatible with various generations of USB devices from Apple, Samsung, Huawei, and more. The device’s 8A overload dual fuse, safety shutters, and plug lock system ensure safety. The unit does not convert electrical output current and voltage.

The Passport GO features four sliding tabs to reveal the different prongs and a USB-C port alongside the three USB-A ports. Thanks to GAN technology,  that USB-C port can output up to 30W. If you’re traveling through multiple countries, this could meet all your needs. It covers 200 countries and regions, including the U.S., U.K., Europe, Australia, Canada, and Japan. It’s easy to use, as you press and slide one of the four buttons to select that plug type and it locks securely in place. Though the USB-C Power Delivery port can put out 30W, that limit is shared with the three USB-A ports. There’s an AC output for larger devices and you could charge five devices at once. Zendure’s travel adapter has a self-resetting fuse, so it will trip to block an overload from damaging your devices and then reset, ready for use again.

Saunorch’s International Travel Adapter is compact and lightweight so it fits easily in your luggage and easily slots into most outlets. It has sliding mechanisms for U.S., Australian, U.K., and EU plugs to cover 150 countries. You can plug one device into the top, with four USB ports on the side for charging additional devices like smartphones and tablets. Each USB port can output a maximum of 2.4A, but the total output is 3.4A, so if you plug in four devices simultaneously, the charging rate is slower for each. It has a 6.3-amp fuse built in, but you do get a spare in case it blows, and you can open the fuse cap with a coin if you need to change it. It’s available in black or blue. The black version has three USB ports and a USB-C port. The USB-C port can output 15W/3A, so it can fast-charge smartphones and tablets.

If you’re planning to stay in one country during your travels, a set of dedicated prongs could be a simple, reliable option. The Bestek Universal Worldwide Travel Adapter Set doesn’t require users to convert or modify anything — each plug works with a specific location. The order comes with eight separate power adapters, which cover a wide range of countries, including the United Kingdom, Europe, India, Australia, Hong Kong, Japan, and Israel. The set is pretty straightforward to use — just hook up the corresponding prongs to the matching plug. Then, plug in your device and go on your way.

The biggest draw to the Mu International Charger is its versatility. This device can support nearly any smartphone or tablet. Whether it’s Android , iOS, Samsung, or another brand, Mu charges them all through a flat tangle-free USB cable. This charger comes with three interchangeable plug heads, and it’s usable in over 200 countries, including throughout North America and the European Union. We appreciate its portability and wide range of capabilities. This charger’s size and compatibility can’t be beaten while you’re traveling, so consider adding one to your bag.

The Evo Global Travel Adapter weighs 50 grams and supports the electrical requirements of more than 150 countries — including the U.S., Europe, and Australia. The adapter’s design capitalizes on a modular system — when you press one button, U.S. or E.U. prongs slide out. If you twist the device, you’ll find the Australian prongs, and if you slide one side prong out, you’ll find the U.K. prongs. This adapter is particularly helpful for travelers with tablets and smartphones because, with a maximum simultaneous output of 12W, the device doesn’t have enough power to support more demanding tech. Even when used explicitly for phones and tablets, the Evo adapter is quite far down on the list of fastest chargers and it’s often finicky when switching to different configurations. We will say the biggest advantage of this product is its affordability and super lightweight.

How to use plugs from United Kingdom in Japan

Plugs, sockets, adapters and other information needed for travelling from United Kingdom to Japan in this page. If you want a report for other countries, re-start the wizard to find to electric adapters for your trip here .

Quick Chart at-a-glance

If you are electrical savvy, perhaps the previous chart is all you need. If this is not the case, you can continue reading and discover what the chart is saying!

Plugs and Sockets at each country

In United Kingdom the following plugs are used: (includes London, Bath, Oxford, Cambridge, Brighton.)

Considerations for the United Kingdom

It is likely you will only find plugs-type "G" in the UK. Plugs type "D" and "M" are considered "old" and not common. They are are still used nowadays to differentiate low-power lighting circuits. So please don't try to use an adapter on them for high-power equipments like hair-dryer or even battery chargers. We keep "D" and "M" plugs in our database as we don't know your exact destination and you might find one next to a bed table. As a rule of thumb , you will probably be fine with the type "G" in hotels and big cities.

... and in Japan you will use: (includes Tokyo, Kyoto, Osaka, Fukuoka, Nagoya, Nagasaki, Sapporo, Southern Okinawa-hontō, Motobu Peninsula, Northern Okinawa-hontō, Naha.)

Considerations for Japan

Users living in Japan have commented to us the outlets type "B" are not common, therefore plugs type "B" might not be easy to plug in Japan.

Take care: Japan uses lower voltage than United Kingdom

Your electric devices from United Kingdom will be expecting 230 Volts, but Japan grid is of 100 Volts, this is a substantial difference that requires you to take some extra steps in preparation to your trip:

On the positive side , nowadays many devices will switch automatically to the network voltage and they will work just fine, i.e. mobile phone chargers are typically multi-voltage (but please, do actually check your own). It is important that you pay attention to your device's voltage. Connecting electronics to the wrong voltage, in the luckiest of the cases, the device will break or stop working temporarily; but please don't take this lightly , in the worst of the cases electrocution and fire hazards are a real possibility .

High-power devices don't usually handle different voltages due to the high-currents involved i.e. anything that its main purpose involves generating heat (or cold) like hair driers, baby bottle warmers, kettles, etc. On the contrary, modern low-power devices are likely to auto-detect and auto-adapt to different voltages i.e. usb chargers, laptop chargers, etc.

You will need a step down voltage converter a device that can be plugged to 100 volts and it provides an outlet with 230 volts for your United Kingdom' device. You will need to pay attention to the maximum power output of the converter and the maximum power consumption of the device.

Different plug systems

Sorry, none of the plugs used in both countries are common. You will definitelly need plug adapters, please continue reading for more information.

Lists of adapters you can use in your travel:

Adapter: generic

This adapter allows you to use plugs type: A, B, C, D, E, F, G, H, I, J, K, L, M, N into outlets type: B.

This adapter allows you to use plugs type: C, D, E, F, G, M into outlets type: A, B.

This adapter is probably illegal in some countries, we put it here for educational purposes; it does not have earth connection but it allows earthed plugs to be connected to it. It has no finger-terminal protection. Try to go for a more expensive and safer alternative.

Adapters you can buy

You can buy the following multi-purpose adapters from Amazon. Please also take a look at the recommended gadgets for your trip.

No equal Hertz

This is not a big issue. Unless you are using an electric alarm clock or some motors when speed is an issue. Explanation: Some alarm clocks uses the frequency of electricity network to measure time. So, time shifts could be experimented. Almost every home electronic device works perfectly with different Hertz.

Japan Travel Adapter – [Power Adapter for Japan]

Japan is an incredible country, but I’ve seen more people confused by their first visit than any other country.  The trains are amazing but confusing.  The food is fabulous but can be a bit overwhelming.  The people are friendly, which means that overcoming language difficulties is a lot easier.  Anyways.  I digress.  I’m here to discuss power adapters for Japan.  We carry around laptops, phones, kindles, and all sorts.  Keeping them charged is key for our travels. And so one of the key items for when we arrive in a country is how to charge our electronics.  So here’s all you need to know about Japan power adapters.  I’ll cover Japan plug adapters, whether you need an adapter for Japan, and Japanese electric adapter requirements too.  Ready?

Best Japan Travel Adapter

This fabulous adapter will cover you  no matter where you’re from. And it’ll cover you wherever you’re going to.

This is the best adapter for travel to Japan.

So let’s start with the basics.  People from all over the world travel to Japan, so I’ll try and cover all the bases.

Electric supplies differ throughout the world.  Voltage ranges from 100 to 240 volts.  If you’re using an appliance that’s rated for a different voltage to the one that’s being received it can be dangerous –  these are mainly heating appliances like hairdryers and you may need to use a transformer, or a voltage converter for your hairdryer to work safely.  (with hairdryers it’s best to use what the hotel provides) And then there’s the fact that Japan may have a different power plug and wall socket than your home country.

Taking the right power adapter for Japan is one of the key things that you’ll need to do before you head to Japan – for other things to do before you travel, our Japan travel checklist is here.

What’s the Electricity Supply like in Japan?

In Japan, the electricity supply is 100 volts.  This is different to most of the rest of the world.

The voltage in Japan is different from North America, which is 120 volts.  Japan’s voltage is different from Central Europe, which is 230 volts.  The United Kingdom operates at 230 volts.  Australia operates at 220 -240 volts.  New Zealand operates at 230-240 volts.

This SK Ross travel adapter supports Japan , and 204 other countries around the world.  It will cover you regardless of the plug type you’re using and what you need to plug into.  It does NOT convert the voltage.  Voltage converters tend to be heavy and expensive.  You’ll only usually need them for some items like hairdryers – and your hotel will provide a hairdryer.

The Japanese Electrical Standards

• Electric plug type A
• Voltage 100 volts
• Frequency 50Hz – 60Hz

What does it mean that the voltage is different in Japan?

It means that you will need to use a power converter to safely use devices – especially if they are heat-generating (like hairdryers).  Many devices have a safe operating limit and you might see technical information that states “Voltage 100 volts to 240 volts”.  This is usual for phone chargers, cameras, and laptops.

Devices that will NOT work as well include curling irons and hair dryers.

What types of plugs are used in Japan?

Two types of plugs are used in Japan.  Type A and Type B. Primarily you’ll find Type A used.

Plug Type A has two parallel flat pins.  A Type A plug looks like this

Plug Type B has a round grounding pin and two flat parallel pins.  The Type B plug looks like this

What types of sockets are used in Japan?

While the primary type of electric socket you’ll find in Japan is Type A, you may also find a Type B socket.  Here’s what these sockets look like

Does Japan use the same plug as the USA?

Possibly.  Japanese sockets and plugs are similar to those in the USA.  There are sometimes differences in prong length, which may mean that your device might not charge. In the main Japan uses a two-pin plug and socket.  Most commonly they are two-pin, non-polarised, and ungrounded.  This means that your plug will fit in a socket.

Some American appliances will work ok in Japanese sockets without an adapter.  Some won’t. 

It is recommended to use an adapter ESPECIALLY for those heating devices – hairdryers, straightening irons, etc, as these devices tend to overheat.  Many – if not all – hotels will provide hairdryers in rooms.  Even the Nine Hours Capsule Hotel that I stayed at provided hair dryers.

Want to read what my experience was like at the capsule hotel? Here you go.

Do you need a voltage converter in Japan?

Possibly, it depends on which devices you are planning on taking.  Most people traveling with laptops, phones, and other such devices – like us – simply use a plug adapter .  Japan works on a completely different voltage than most of the rest of the world. Some of your devices may be certified to “work” at 100 volts, but some of them won’t.  99% of travelers manage with just a plug converter.  Voltage converters tend to be heavy and expensive and most devices that we use every day are fine with a plug converter

What type of plugs are needed in Japan?

You’ll find several types of sockets (and plugs) in Japan, most of them have two flat parallel pins and are often non-polarized.

If you’re traveling on Japanese trains (and making use of the JR Pass ), you’ll need a plug that fits in a Type A socket.

What is the recommended power adapter for Japan?

A recommended power adapter for Japan will ensure that your plug then fits into the socket in Japan.  We’ve used SK Ross devices around the world for more than 10 years now, and this power adapter has covered us in all the 110 countries, that we’ve traveled to, including Japan.

Final Words on Travel Adapters for Japan

Japan is unique in using 100 volts for its electricity, which means that while some of your devices will be compatible when charging in the country, not all of them will be.  Also, depending on which country you and your devices are from, your plugs might not fit the electric sockets that you’ll find in Japan.  So plan ahead.  It’s pretty tough to try and find an electrical adapter once you’ve arrived in Japan and it’s best organized and bought before you leave home.

US to Japan Power Adapter: What Plug Do I Need? (2024)

A surprising mix of ultra-modern technology and deeply revered tradition, Japan is a fascinating place to visit. Whether you’re seeking sandy beaches, mountain villages, or vibrant cities – it has a little something for everybody.

But while electricity isn’t something most travelers give much thought to, the Japanese electrical grid has some unusual quirks. Make sure you understand how it works, and determine whether you’ll need a US-to-Japan power adapter or converter to protect your cherished devices from damage.

Which power outlets do they use in Japan?

Japan is one of the only countries outside the Western Hemisphere to use Type A and B outlets, the same as in the US. Type A sockets are ungrounded and have two flat holes, while Type B sockets are grounded and have a third hole. Unlike in the US, the ungrounded, two-flat-pronged outlet type (pictured) is most common in Japan.

The electrical grid in Japan has two other oddities. Most countries use the same frequency everywhere, but that’s not the case in Japan.

In the eastern part of the country, including Tokyo, the frequency is 50 Hz; in the Western part, including Osaka and Kyoto, it’s 60 Hz. The difference in frequency generally isn’t an issue, but it can prevent clocks and timers from keeping time correctly.

The voltage used in almost every country is either 120V (in North America) or 230V (in most other countries); however, Japan uses a voltage of 100V, the lowest in the world.

Even though the electrical grid in the US uses a voltage of 110V, many American appliances are rated for a range of 100-120V.

What kind of power adapter do I need for Japan?

“What adapter do I need for Japan?” is a good question if you’re making your first trip to Tokyo or another Japanese destination – but you might not need one at all. Any devices with the plug type with just two flat prongs (Type A) won’t need a US-to-Japan power adapter; they can be plugged straight into any outlet in Japan.

However, an adapter is essential if anything you’re bringing has a plug with a third-round prong (such as a laptop). You may find some Type B sockets, but they’re the minority in Japan. Check the plug on any devices you bring to decide if you need a US-to-Japan power adapter.

If you want to plug in any Type B devices while in Japan, we recommend this Universal Adapter .

Not only will it have you covered during your stay here, but it also works in 100+ popular countries so you won’t need to buy constant replacements for unique outlets. It even comes with a lifetime replacement guarantee, which means it’s the last adapter you’ll ever need to buy!

Other Japan Packing List Items

In addition to your US-to-Japan power adapter, these items will help you pack with intention and expand the possibilities of your getaway. Also, check out our Japan packing list for more inspiration and ideas:

1. Neck Wallet

Pickpocketing can happen anytime, anywhere. So it pays to be careful with your valuables, especially in crowded places and at tourist hotspots. Using a neck wallet is the easiest way to keep everything secure. This one can hold all of your cash, credit cards, phones, and passports, which will make travel days way easier. You don’t want to flash your wallet over and over, which can make you an easy target. But this discreet case can be worn under your shirt so thieves won’t even notice it. The internal lining material is also RFID-blocking, which means modern thieves can’t scan your credit cards from afar!

View on Amazon.com ➜

2. Lipstick-Sized Portable Charger

Whether you want to take photos of the cherry blossoms or look up the train schedule, you’ll be out of luck if your devices are dead. But all you need to keep them juiced is a tiny charger you won’t even notice in your bag. Bring this lipstick-sized portable charger along, and you can make sure your devices stay powered throughout the day. You never know when an emergency will come up!

3. Virtual Private Network (VPN)

Japan has lost millions of dollars to cybersecurity attacks and is only ranked behind the U.S. for the highest world losses due to online theft. Ensure you have a safe connection when you join public Wi-Fi networks at cafes, coffee shops, airports, hotels, and more – because these are breeding grounds for malware, ransomware, and IP theft.

We use NordVPN because they have unlimited bandwidth and are the fastest VPN provider we’ve tried. They will protect your private data like passwords, credit card numbers, and social security numbers, so you can surf the web with peace of mind. I wish I had known about this before my credit card number was stolen on vacation at (what I thought was a safe) Airbnb. Now, I always use a VPN when traveling and while at home. It’s a small price with a big payoff! And will mitigate any online censorship you experience while abroad.

4. Windproof Travel Umbrella

Most areas of Japan encounter considerable rain throughout the year, with the Summer months being the peak. You’ll want to arrive to Japan prepared for a rainy day or two. This well-made, compact travel umbrella will hold up even on a stormy day. When you don’t need it, it’s small enough to stow in your daypack and comes with a zip case so your other items will stay dry.

5. Jet Lag Relief

Coming from the US, the time difference can be 15 hours or more, which is a recipe for serious jet lag! Too many travelers end up spending their first days in Japan napping instead of exploring, but that doesn’t have to happen to you. Bring some jet lag relief pills, and you’ll adjust in no time. These are homeopathic with no side effects and use a botanical recipe to calm the system.

6. Travel Insurance for Japan

Your domestic provider does not extend overseas and you don’t want to risk paying out-of-pocket for lump sums. Nobody wants to think about getting sick or having an accident while traveling, but it happens. This is why we always come prepared with travel insurance to protect the investment we’ve already made in our trip. They cover you for common issues, like medical emergencies, flight delays, cancellations, baggage loss, theft, and the ability to “cancel for any reason.”

We use Faye because they’ve modernized travel insurance, and are the first 100% digital provider. You can quickly and easily make claims to get reimbursed straight from your phone through their convenient mobile app. Just as you wouldn’t own a home without home insurance, you shouldn’t travel without travel insurance. It’s a small fraction of your trip cost and worth it for the peace of mind alone.

7. Packing Cubes

Thanks to packing cubes, you no longer have to sift through every single item in your bag to find what you’re looking for. Instead, pack each type of clothing in a clearly labeled packing cube (pants, shirts, essentials, etc.), and you won’t have to scramble for that missing sock or concert shirt. It also makes unpacking and repacking a breeze since you can move cubes easily from your suitcase to the hotel drawers to a backpack for daily excursions. This set also comes with bonus laundry bags, and you can opt for the 3-pack if you’re not ready to commit to the full set.

8. Luggage Straps

If you’re new to luggage straps, prepare to have your life changed! For avid travelers, these are a must-have addition to your packing list since they can serve a variety of purposes.

Secure your luggage so nothing breaks open mid-transit, deter theft, easily identify your bag at the arrivals terminal, tether bags together for easy maneuvering through busy places, create a makeshift handle if anything breaks, and more! Pretty much anything you could use a rope or adjustable belt for, you can use this strap for. It fits on nearly any bag and has unlimited uses, plus a built-in contact card in case anything gets lost.

9. Water Bottle with Built-In Filter

While tap water is supposedly safe in Japan, I never risk it when traveling. Even when it’s bacteria-free, tap water often still contains harmful heavy metals and other pollutants. That’s why I love traveling with my Grayl bottle. It can filter out viruses, bacteria, heavy metals, pesticides, microplastics, and chemicals. You’ll always have a convenient source of clean water, save money, and reduce plastic waste – triple win!

10. Quick-Dry Travel Towel

From snorkeling the Keramas Islands to relaxing in the hot springs of a local onsen, you’ll appreciate having a fast-drying travel towel on hand. They are compact and lightweight, so they’re easy to throw in any daybag. I always prefer to bring my own towel on excursions because you never really know how clean are the ones they give out on tours. This one dries 10x faster than cotton and is very multi-purpose.

11. Hanging Toiletry Bag

Bathrooms in Japan can range from luxurious to slightly strange. You’ll enjoy the heated seats and high-tech gadgets, but you may not love the limited countertop space or squat toilets (a hole in the ground). Regardless of what bathroom situation you’re up against – use this hanging toiletry bag to stay organized. With a 360-swivel hook, it can hang on any door, wall, or shower pole to create a handy shelf-like system for your self-care items.

This bag is our favorite because it’s designed in Hawaii by an ethical company supporting women’s education. It’s made by travelers who were looking for a better product, so they designed their own! It has 4 inner pockets for larger items like skincare, haircare, and makeup, as well as 3 external compartments for smaller items like cotton rounds and jewelry.

12. Activated Charcoal

The cuisine of Japan is incredible! But you’ll also be facing a lot of street food and raw fish. To combat any potential food poisoning, bring these activated charcoal supplements to expel any toxins from your system quickly. Traveler’s diarrhea is common for anyone abroad, but these will help you get back on your feet more quickly.

13. TSA-Approved Luggage Locks

When flying to Japan, your checked luggage will be out of your hands for many hours. To decrease the likelihood of anyone stealing your belongings in transit, secure your bags with luggage locks. They’re also useful for locking lockers at tourist sites and hostels and are a smart way to keep pickpockets out of your daybag. This 2-pack of TSA-approved locks is durable and won’t cause you any delays through security. You can count on them for your trip to Japan and all of your trips to come!

14. Packable “Just in Case” Bag

From kimonos to tea to handmade art – you will definitely want to bring back some stunning souvenirs from your adventures! The “just in case” bag is the perfect solution to overpacking since it can count as your personal item on the flight home. It fits neatly under your plane seat and allows you to skip those pesky carry-on fees! Fill it with gifts for yourself and loved ones.

15. Cooling Towel Set

Summers can get hot in Japan, and if you’re outside doing any physical activity, it’ll feel even hotter. From hiking at the base of volcanoes to city walking tours, a cooling towel is a refreshing relief whenever you sweat. All you have to do is get the towel wet and wring out excess water, and it instantly becomes ice-cold. Place it around your neck, shoulders, or forehead, and enjoy the cooling relief. It’s deluxe!

16. Travel Sheets

It’s a long journey to Japan and you may find yourself sleeping in some strange places like planes, trains, buses, hostels, and capsule hotels. In case you don’t have sheets (or they’re not as clean as you’d like) – these travel sheets are a wise precaution. They’re super lightweight but will help you rest, even in the strangest of places.

What’s the electricity and power supply like in Japan?

As one of the world’s most technologically advanced countries, Japan doesn’t experience unexpected power outages very often. Like any country, Japan is susceptible to power outages caused by heavy storms or natural disasters.

Following major earthquakes in 2011 and 2018, blackouts crippled large parts of the country.

Do I need a voltage converter for Japan?

Whether you need a US-to-Japan voltage converter depends on the devices you plan to bring. You’ll need to check the tiny writing by the plug on each device to see its rated voltage. If the lower end of the range for a given device is above 100V (110-120V is common in the US), you’ll need a converter.

Plugging an American-made 120V device into a Japanese outlet probably won’t destroy it, harm you, or start a fire. But the device may not function or might not work as well as usual, and it could cause minor damage. If you’re bringing anything that isn’t rated for use at 100V, play it safe and get a US-to-Japan voltage converter.

2. What is the weather like in Japan?

Japan is made up of four main islands and several smaller ones, and weather patterns throughout the country vary considerably. The northernmost island of Hokkaido is the coldest (with average highs below freezing in the winter) and receives the most snow; the northern part of Honshu, Japan’s main island, has similar weather. The southern islands and even the central and southern parts of Honshu (including Tokyo) are notably warmer year-round. These areas get infrequent snow, and temperatures usually stay above freezing, even in the winter.

Outside of Hokkaido, most of the country experiences high temperatures and intense humidity in the summer, with heavy rainfall between late spring and early fall. Typhoon season peaks in August and September, primarily affecting the southern regions of the country, including Okinawa.

5. How to see the cherry blossoms in Japan?

Asher Fergusson

In Japan, power plugs and sockets (outlets) of type A and type B are used. The standard voltage is 100 V at a frequency of 50 / 60 Hz.

• Yes, you need a power plug travel adapter for sockets type A and B in Japan.
• You also need a voltage converter.
• Be extra careful with certain devices because of the difference in frequency.

Do your power plugs fit in Japan?

In Japan, they use power sockets (outlets) of type A and B. In the United Kingdom, you have plugs G. You need a power plug adapter in Japan for sockets type A and B. The plugs of your electric devices don't fit without.

Buy a power plug (travel) adapter

We don't sell power plug adapters. We refer you to Amazon, where you will find a great selection of travel adapters.

• Find travel adapters at AMAZON.CO.UK

You need to look for a power plug adapter for sockets type A and type B. Alternatively, choose a world travel adapter that fits multiple sockets, in case you travel more often.

Voltage converter needed in Japan?

The standard voltage in Japan (100 V) is much lower than the voltage level your devices typically operate at in the United Kingdom (230 V). Additionally, be aware that the frequency in Japan differs.

• You need a voltage converter in Japan.
• Try to find a voltage converter that can also change the frequency.

A voltage converter will ensure a safe input voltage level for your devices in Japan. You can find voltage converters at Amazon.

• Find voltage converters at AMAZON.CO.UK

A suitable voltage converter can sometimes be hard to find. Some suggest that it is possible to cautiously use your electric devices in Japan without a converter. While they most likely won't be damaged, they may not function optimally. A low voltage can lead to overheating and a reduced lifespan. The wrong frequency can also cause unexpected behavior. If you want to try without a converter (at your own risk), exercise special caution with motorized devices and those containing electronic chips, such as clocks, shavers, and medical devices. If you don't want to take any chances, use a voltage converter in Japan.

To be sure, check the label on your devices. Some devices never need a converter. If the label states 'INPUT: 100-240V, 50/60 Hz' the device can be used in every country in the world. This is common for devices with chargers like tablets/laptops, photo cameras, cell phones, toothbrushes, etc. For these devices you will only need a power plug adapter.

Mount Fuji view to be blocked as tourists overcrowd popular photo spot

Fujikawaguchiko town official says choice to erect huge barrier is ‘regrettable’ and last resort

A huge barrier to block views of Mount Fuji will be installed at a popular photo spot by Japanese authorities exasperated by crowds of badly behaved foreign tourists.

Construction of the mesh net – 2.5 metres (8ft) high and the length of a cricket pitch at 20 metres – will begin as early as next week, an official from Fujikawaguchiko town said on Friday.

“It’s regrettable we have to do this, because of some tourists who can’t respect rules,” leaving litter behind and ignoring traffic regulations, he told Agence France-Presse.

It is the latest direct action in Japan against over-tourism after residents of Kyoto’s geisha district banned visitors from small private alleys this year.

Record numbers of overseas tourists are travelling to Japan, where the number of monthly visitors exceeded 3 million in March for the first time.

Mount Fuji, Japan’s highest mountain, can be photographed from many spots in the resort town of Fujikawaguchiko. This viewpoint is particularly popular because the majestic – and active – volcano appears behind a Lawson convenience store, which are ubiquitous in Japan.

Due to this visual juxtaposition, “a reputation has spread on social media that this spot is very Japanese, making it a popular photo location”, said the town official, who declined to be named.

The mostly non-Japanese tourists are overcrowding a stretch of pavement next to the Lawson shop, he said.

After traffic signs and repeated warnings from security guards were ignored, the town in Yamanashi region decided on the huge screen as a last resort.

The measure is also meant to protect a nearby dental clinic against tourists who sometimes park there without permission and have even been seen climbing on to the roof of the clinic to get the perfect shot, the official said.

The town wished it had not been forced to take action, the official said, adding that the current plan was for the screen to stay up until the situation improves.

Japan has been a booming tourist destination since pandemic-era border restrictions were lifted, and the government has been working hard to boost visitor numbers. But this has not been universally welcomed, including in Kyoto, where people have complained of snap-happy tourists harassing the city’s immaculately dressed geisha.

This summer, hikers using the most popular route to climb Mount Fuji will be charged ¥2,000 each (£10.50, $13.35, A$20.50), with numbers capped to ease congestion.

Other destinations are also struggling with over-tourism. On Thursday, Venice began charging day-trippers to enter the city, while last week tens of thousands of people across the Canary Islands called for a freeze on visitor numbers .
