Introduction to Japan Plug Types
Japan primarily uses two types of electrical plugs, known as Type A and Type B. These plug types are also used in North America, Central America, and some other countries. Here's a detailed overview of the Japan plug types you will encounter:
Common Sockets in Japan
In Japan, the most common electrical sockets (power outlets) are Type A and Type B.
- Type A: This is an ungrounded socket with two flat parallel pins. Most Japanese outlets are Type A.
- Type B: This is a grounded version of Type A with an additional round pin for grounding. While less common than Type A, Type B sockets can also be found in Japan, especially in newer buildings and facilities.

What Voltage and Frequency is Used in Japan?
- The standard voltage in Japan is 100 volts, which is lower than the North American standard of 120 volts.
- 50 Hz in Eastern Japan (Tokyo, Yokohama, Tohoku, and Hokkaido) & 60 Hz in Western Japan (Osaka, Kyoto, Nagoya, Hiroshima).
Do I Need a Travel Adapter for Charging in Japan?
If you're traveling to Japan from a country that uses a different voltage and/or plug type, you will need a conversion plug or a power adapter to use your electronic devices. Here's what you should consider:
- 1. Plug Adapter: If your devices can handle 100 volts and only the plug shape is different, you'll need a plug adapter. This adapter does not change the voltage; it simply allows your device's plug to fit into the Japanese power outlet.
- 2. Voltage Converter/Transformer: If your devices are not compatible with 100 volts and are designed for a higher voltage (such as 220-240 volts, common in Europe and many other parts of the world), you will need a voltage converter or transformer to step down the voltage to 100 volts.
- 3. Dual-Voltage Devices: Many modern electronic devices, such as laptops, smartphones, and camera chargers, are dual voltage, meaning they can operate on a range of voltages from 100 to 240 volts. For these devices, you only need a plug adapter, not a voltage converter.
Tips for Charging Your Devices in Japan
When traveling to Japan, you'll need a travel adapter to charge your devices because the electrical outlets and voltage may differ from those in your home country. Here's tips for charging your devices:
Smartphones and Computers
Most modern smartphones, tablets, and laptop chargers are designed to handle a range of voltages from 100V to 240V, so you typically only need a plug adapter to charge these devices in Japan.
Hair Dryers
Check if your hair dryer is dual-voltage. If it is, you can switch it to the 100V setting and use it with a plug adapter in Japan. If not, it's usually better to use a dual-voltage travel hair dryer or purchase one locally in Japan that is designed for the 100-volt system.
USB Charger
Source: Amazon
For devices that charge via USB, a universal travel adapter with built-in USB ports can be very convenient.
Power Strip
Source: Amazon
If you have multiple devices, consider bringing a power strip (without surge protection, as it may not work with different voltages) from your home country along with a single travel adapter to plug the strip into the Japanese outlet.

How Voltage and Frequency Differences Affect Devices in Japan
In Japan, the standard voltage supply is 100 volts, which is lower than in many other countries. For example, in the US, the standard voltage is 120 volts, and in most of Europe, it is around 230 volts. The frequency is 50 Hz to 60 Hz. Here's how these voltage and frequency differences can affect devices:
- Foreign Devices in Japan: Devices from countries with higher standard voltages may not work as efficiently when plugged into Japanese outlets. In some cases, they might require a voltage transformer or a power converter to function properly.
- Frequency Difference: The difference in frequency can affect timing devices and appliances with motors. For example, an electric clock designed for 60 Hz may not keep accurate time if operated at 50 Hz. Similarly, appliances like fans and ovens may not function as intended if the frequency is lower.
- Safety Concerns: Using devices at an incorrect voltage can pose safety risks, including electrical shock, short-circuiting, and fire hazards. It's essential to check the voltage specifications on electronic devices and use appropriate transformers or converters when necessary.
Where to Charge Your Devices Easily in Japan?
Charging your devices in Japan is relatively easy, as there are various options available. Here are some places where you can charge your devices:
- 1. Convenience Stores: Many convenience stores like 7-Eleven, FamilyMart, and Lawson have charging stations. Some may offer this service for free, while others might charge a small fee.
- 2. Cafés and Restaurants: Some cafés and restaurants provide power outlets for customers to use. Look for outlets near seating areas or ask the staff if it's okay to charge your device.
- 3. Train Stations: Major train stations often have charging stations or outlets available for public use. These can be found near seating areas or within waiting lounges.
- 4. Shopping Malls: Large shopping centers and department stores sometimes have charging stations or lockers where you can securely charge your phone while you shop.
- 5. Airports: Major Japan airports, including Haneda Airport and Kansai Airport, are equipped with numerous charging stations in the terminal areas.

Central Tokyo Tokyo|2.87km from city center
This is the hotel I always stay at whenever I visit Tokyo, and it never disappoints.
The location is fantastic. Since the Prince Hotel is right across the street, there are plenty of excellent restaurants and dining options nearby, which is a huge plus.
Transportation is also incredibly convenient. Moving to major districts like Shinjuku, Ginza, and Shibuya by train/subway is fast and easy. If you are looking for a central base in Tokyo with great food and accessibility, I highly recommend staying here.From€163

Ginza/Tsukiji Tokyo|0.49km from city center
This room size is just right for one person without luggage. I'm not sure what tier it falls into in Japan, but in China, it's probably on par with or slightly below a Hilton. I'd be willing to stay here again on my next trip to Tokyo. There's a Kyushu ramen place nearby that's quite good, but I wouldn't really recommend Yuzugumi (Oil Group).From€187

Ginza/Tsukiji Tokyo|0.66km from city center
When doing my research, I was drawn in by the overwhelmingly positive reviews on social media. You can really feel the meticulousness of an established hotel here. The room was well-maintained, the toiletries smelled lovely, and the shower pressure was surprisingly strong. The heated toilet seat was a nice touch. Most of the staff were polite and service-oriented. Many people greeted me good morning when I left, which was a pleasant surprise. Although the breakfast selection wasn't huge, the variety on offer was thoughtfully presented. There was a round-faced female staff member at breakfast who was very enthusiastic. The transportation is quite convenient, with a 7-Eleven and some small shops nearby. While the desserts were a bit too sweet for my taste, they offered great value for money, and the dessert staff were very polite.
However, I must specifically point out that the attitude of a staff member named Abe at the 17th-floor breakfast entrance made me very uncomfortable.
After booking, I had emailed the hotel multiple times to confirm if three adults and one child could stay, and I had selected the correct number of people and paid for four. The response I received was that I would need to pay an additional breakfast fee for the child after check-in. So, when the front desk said we didn't need to pay an extra child's breakfast fee during our first night's check-in, we were surprised. The next day, when we arrived at breakfast, we were told we still needed to pay for the child's breakfast. Because this conflicted with what the front desk said during check-in (though it did align with the email we received before our trip), my husband was trying to explain the front desk's statement (he had only started explaining half a sentence and hadn't finished, with no intention of not paying). This staff member impatiently interrupted him. Even after we clearly stated our numbers, he still pointed his finger and counted us, which seemed very impolite. I believe that in the Japanese service industry, this is considered rude. Afterward, I felt it was unnecessary to explain further, so we let it go.
The second morning at breakfast, we had just arrived at the restaurant entrance. Since everyone was sitting and no one was standing, I didn't realize we needed to get a number. Again, it was this Mr. Abe. Not only did he not greet us, but he very unpleasantly said, 'everyone must wait,' seemingly assuming we didn't want to queue, when in fact, we had no idea we needed to (because this wasn't the case the day before). Before explaining things to us, this staff member always seemed to assume we were rule-breakers and immediately started judging and criticizing. Meanwhile, he treated the European and American guests before and after us with great patience, courtesy, and a big smile, which made me feel discriminated against. I never expected that the most uncomfortable experience of my Tokyo trip would come from what seemed like the least likely place – a well-known hotel. When I recall this hotel, all I can think of is his subtle expression. I hope to receive a handwritten apology from him. I hope that before he discriminates against Chinese guests in the future, he will remember that he is a hotel professional.From€219

Ginza/Tsukiji Tokyo|0.18km from city center
The location is fantastic! It's less than 100 meters from Kyushu Ramen, and Yu-gumi (a popular bathhouse) is also nearby. There's a great yakiniku (grilled meat) restaurant next door with excellent quality meat. You're surrounded by food options, and Don Quijote and Lawson are also very close. It's super convenient to drop off your shopping bags at the hotel after a stroll in Ginza, or just head back for a quick rest if you're tired. Getting to other places is a breeze too, as the subway station entrance is right downstairs. The bed is large, and the bathroom and shower are separate, both quite spacious. For one person, the room size feels just right, but it might be a bit snug for two people or if you have two large suitcases.From€177

Suidobashi/Tokyo Dome Tokyo|3.75km from city center
I stayed at the Tokyo Dome Hotel from January 31st to February 3rd, 2026. The hotel's location is excellent, right next to Tokyo Dome, and it's just a 3-5 minute walk to either the subway or JR station. The lobby is spacious, and check-in and check-out are handled conveniently via self-service machines. Compared to other hotels in Japan, the rooms here are quite roomy and bright. We booked a twin room, and it was a very generous 33 square meters. The hotel features transparent glass observation elevators, offering views of the Tokyo Skytree. Do note that room prices at this hotel fluctuate significantly based on events at Tokyo Dome, with rates potentially doubling or more.From€80

Tokyo Tower Area Tokyo|2.41km from city center
The hotel indeed has an unparalleled location, but the front desk was truly disappointing. It felt like the Japanese staff treated Chinese guests differently, perhaps due to over-promotion.
I specifically booked a room with a full panoramic view of Tokyo Tower and even emailed two weeks in advance, requesting a high-floor room if possible. The hotel replied they would try to accommodate. Upon arrival, I was told the famous room 17 wasn't available unless I paid extra to upgrade to an even higher floor. This was somewhat expected, so I wasn't too upset.
What truly annoyed me was that the panoramic room I specifically booked was for a high floor, clearly stated as floors 19-28. Despite my advance request, they only gave me a room on the 19th floor. I immediately complained that the floor was too low, but the front desk pretended to check twice, claiming there were no higher floors or available rooms, unless I paid more. Rooms below the 18th floor were clearly cheaper by over 500 yen, so booking a high floor had been pointless.
After repeatedly refusing to pay extra and refusing to check in, the front desk finally agreed to switch me to a room on the 28th floor, in the exact same position. This hotel clearly had available rooms but deliberately tried to induce customers to pay more. Keep this in mind.From€215

Akasaka Tokyo|2.21km from city center
Room and bed were very comfortable, immaculately clean and modern. 2 mins walk from train station, if you need lift access to train then a 6 mins walk, we had a stroller.
Breakfast was a bit of a zoo, we went during Christmas, very busy! But tables were spacious so even though there were so many people you don’t feel cramped. Good variety of food selection. We had dinner at the Japanese teppanyaki restaurant. Delicious, especially the tuna salad.
I found the lobby staff a little lack of personality, at check in, no mentioning of where breakfast will be, what time check out is. Just checked you in and that’s it, no personal notes in the room. When I expressed I’ve lost my phone at the shop in Tokyo, no sign of empathy (it was a western male staff) no gesture of helpfulness, very cold and robotic. This goes for concierge also, he is an older western gentleman, he needs to use Google translate also which is frustrating cause I could do exactly the same research with Google translate.
Overall, hardware is solid, need to fine tune the staff, sprinkle a little bit of personality in them.From€383

Odaiba Tokyo|5.01km from city center
Good service, but maintenance and consistency could be improved.
I stayed for 3 days and 2 nights. While the overall service and location are good, a few details made the experience fall short of true 5-star standards.
Pros:
• The washroom is spacious and clean, with strong shower pressure that feels great after a long day out.
• The anti-slip mat is a thoughtful touch since the bathtub can get slippery.
• Toiletries and body lotion are of decent quality.
• The in-room iron is convenient, no need to request one.
• The room includes a small balcony and is non-smoking friendly.
• The complimentary slippers are comfortable and well-made.
• Staff are polite and helpful throughout my stay.
Cons:
• The bathroom mirror fogs up completely after showering — it would be great if anti-fog mirrors were installed.
• My room key card was disabled after the first night, requiring a trip to the front desk for reactivation.
• The cupboard doors are old and difficult to open, making noticeable noise.
• Breakfast is decent but repetitive. During peak times, guests were directed to a temporary seating area where food wasn’t replenished promptly.
• After housekeeping, my used towels were removed but not replaced.
• The carpet feels dusty, suggesting it could use a deep clean or refresh.
Overall:
The staff are courteous and professional, and the basic comfort level is good. However, for a 5-star hotel, the property feels a little dated and service consistency needs improvement. With some attention to maintenance and small operational details, this could easily become a much better experience.From€193

Ginza/Tsukiji Tokyo|0.31km from city center
Honestly, aside from the price, this hotel has no flaws. It has its own natural hot spring, free to use after 3 PM as long as you follow the communal bathing rules. After a thorough rinse, you can enjoy a relaxing soak. From 5 PM onwards, there's even complimentary alcohol served on the first floor.
Every day, you can choose free pajamas and pillows, with various softness and firmness options available. There's an ice machine on each floor, where you can also get iced water.
Fresh and clean bath towels and other linens are provided daily.
The service is incredibly attentive and meticulous. Every time you leave, someone at the front desk wishes you a safe journey. When checking out, someone at the door will open it, bow, and wish you a safe trip.
Downstairs, there's a ramen shop open until 4 AM, so even if you miss dinner sometimes, you're in the central Ginza area, with countless restaurants open until the early hours just a few steps away.
The K S Higashi-Ginza Station is right at the doorstep. Across the street is the Higashi-Ginza Line of the Hibiya Line, and just one more street over is the Ginza Station of the Ginza Line, making transportation extremely convenient.From€63

The hotel's location was excellent, and the rooms were very spacious, exceeding my expectations. The hotel was immaculately clean, truly spotless. Each floor has six rooms that share a common lounge area. After each use, staff would come to clean it thoroughly, restoring it to its pristine condition, which was incredibly thoughtful. Every staff member at the hotel was extremely kind and friendly. I particularly loved the rooftop hot spring; after a soak, they even provided ice-cold milk, which was a lovely touch.

Shinjuku Area Tokyo|5.43km from city center
I really wanted to love this hotel, but it fell flat in several ways.
What I didn’t like:
The twin room is tiny—shockingly small—and there’s no tub, which is odd given the “onsen” branding.
The onsen itself isn’t worth the hype. It’s very small and almost always crowded, so it doesn’t feel relaxing at all.
The hotel uses central air per floor, meaning your room temperature depends on what other guests want. You can end up freezing at 2 a.m. with zero control.
Location isn’t great. It’s farther from the train stations than advertised, and you feel it after long days exploring.
They gave me a hard time about letting my friend come up to my room just to drop off her bags while we went on a side trip.
Small gripe, but the toilet was disappointing for Tokyo—cold seat, no automatic features. My hotel in China had a fully automated heated seat that opened when you walked in, so this felt like a downgrade.
What was good:
7-Eleven is right outside the door, super convenient.
Cute coffee shop about a block away.
Staff were friendly and tried to be helpful.
Overall:
Not a great stay. I wish I had booked somewhere with better room comfort, easier transportation access, and more nightlife around. I wouldn’t choose this property again.From€149

Onyado Nono's quality is consistently reliable across all its branches. This particular one, located in bustling Asakusa, is incredibly convenient for travelers. The hotel is just a short walk behind the temple, with numerous food stalls and supermarkets nearby. One of the supermarkets even has a 24-hour basement food section, which is incredibly convenient! The only minor drawback is that, being in a popular tourist area, the streets can get a bit noisy at night.From€90

Odaiba Tokyo|4.46km from city center
Cleanliness: No issues.
Ambiance: I had a room with a view of Ariake Arena, which was generally nice. The bedroom is right as you enter, so all bedrooms are quite spacious. The bathroom is at the very back. If you don't like the bed being right by the entrance, you might want to avoid this. Also, the bedroom doesn't get much natural light because the bathroom is on the outside with a window (a transparent glass bathroom).
Service: If you're coming to the hotel from outside the building, there are absolutely no signs, elevators, or escalators to get to the hotel lobby on the 2nd floor. You have to carry your luggage up the stairs to reach the hotel's main entrance. It's hard to imagine a hotel of this caliber having such an arrangement.
Facilities: It's hard to believe that a hotel at this price point and level doesn't come standard with a bathtub.
To clarify a misconception: no room in this hotel offers a direct view of Big Sight.From€60
FAQs about Japan Plug Type
What is the voltage and frequency used in Japan?
The standard voltage in Japan is 100 volts, which is lower than in many other countries. The frequency is 50 Hz in Eastern Japan (including Tokyo, Yokohama, Tohoku, and Hokkaido) and 60 Hz in Western Japan (including Osaka, Kyoto, Nagoya, Hiroshima).Do I need a voltage converter for my devices in Japan?
If your device is not rated for 100 volts and is not dual-voltage (100-240V), you will need a voltage converter to safely use it in Japan.Can I use my Type B plug in a Type A socket?
You can physically fit a Type B plug into a Type A socket because the two flat pins are the same. However, since Type A sockets in Japan are not grounded, the grounding pin on the Type B plug will not function.Is it safe to use electrical appliances in the bathroom?
As in many countries, it is generally not safe to use electrical appliances near water due to the risk of electric shock. Use appliances in the bathroom only if they are specifically designed for that environment and follow all safety instructions.
