Japan uses Type A and Type B power plugs and operates on a 100V electrical system. Travelers from the US, Canada, or Mexico usually won’t need a plug adapter, while visitors from Europe, the UK, Australia, and many other countries will.

 

Most modern electronics like smartphones, laptops, and cameras are dual-voltage, so they work safely in Japan. High-power appliances such as hairdryers or straighteners may require a voltage converter.

 

A universal travel adapter is recommended to keep all your devices charged. Being prepared ensures a smooth and worry-free trip while exploring Japan.

What type of  Sockets and Plug Types are used in Japan

Plug type A and B

Japan uses a standardized system for power outlets, making it relatively easy for travelers to navigate. Knowing the right Japan plug types before you arrive ensures your devices stay powered throughout your trip.

 

Primary Plug Types in Japan: Type A and Type B

 

Type A Plug (NEMA 1-15): This is the most common plug type in Japan. It has two flat, parallel pins and is ungrounded, meaning it does not include a third pin for grounding. This design is the same as the Type A plugs used in North America, making it convenient for travelers from the US and Canada.

 

Type B Plug (NEMA 5-15): Less common in Japan, the Type B plug has the same two flat, parallel pins as Type A, plus a third round grounding pin. This provides a safer connection for devices that require grounding, such as some laptops or high-power appliances.

 

What This Means for Your Devices

 

Most wall outlets in Japan found in homes, hotels, and public spaces are designed for Type A plugs. While some Type B devices may fit into a Type A socket, it is not always safe. The lack of grounding can pose risks for certain electronics, so it’s important to check your devices and bring the appropriate Japan power plug adapter if necessary.

Do You Need a Plug Adapter for Japan?

Whether you need a Japan plug adapter depends on the plug types and voltage used in your home country.

 

Travelers from the United States, Canada, or Mexico

Good news! The Type A and Type B plugs used in these countries are the same as in Japan. You can connect your devices directly to most Japanese outlets without a physical adapter. However, be mindful of the voltage difference, which can affect certain electronics.

 

Travelers from Europe, the UK, Australia, Asia, or Other Regions

If your home country uses plug types like C (Europlug), G (UK plug), I (Australian plug), or others, you will need a Japan plug adapter. These plugs will not fit into Japan’s Type A sockets, so bringing an adapter is essential for charging your devices safely.

 

Recommended Japan Plug Adapter

A universal international travel adapter is highly recommended. These compact devices feature interchangeable heads that allow you to connect your home country’s plugs to Japanese outlets. Make sure the adapter explicitly supports Type A and Type B plugs for maximum compatibility.Even if you forget a 

 

  • Major Electronics Retailers: Stores like Bic Camera, Yodobashi Camera, or Yamada Denki carry a wide range of adapters.
  • Airport Shops: Narita, Haneda, and Kansai International Airports have kiosks selling travel essentials, including adapters.
  • Convenience Stores: Some larger Lawson or 7-Eleven locations in tourist areas and near train stations stock basic adapters.

What Makes Japan’s Electrical System Different?

Understanding the Japan voltage and electrical frequency is essential if you want to keep your devices safe while traveling.

 

  • Japan Voltage: 100V
  • Japan uses a 100V electrical system, which is lower than most countries around the world:
  • North America: 120V
  • Europe, the UK, Australia: 220–240V

If you plug a 240V device (like many European hair dryers or kettles) into a 100V outlet in Japan, it may run weakly—or not work at all. On the flip side, plugging a 100V Japanese device into a 240V outlet abroad can permanently damage the appliance.

 

Japan Electrical Frequency: 50 Hz & 60 Hz

Japan is unique in having two different power frequencies:

  • 50 Hz in Eastern Japan (Tokyo, Yokohama, Tohoku, Hokkaido)
  • 60 Hz in Western Japan (Osaka, Kyoto, Hiroshima, Nagoya)

For most travelers, this frequency split won’t matter. Modern electronics—such as smartphones, laptops, tablets, and camera chargers—are designed to handle both 50Hz and 60Hz. Only older or motor-based appliances (like analog clocks or older electric shavers) may be affected.

Do You Need a Voltage Converter for Japan?

A voltage converter is different from a plug adapter. While an adapter only changes the plug shape, a converter changes the electrical voltage to match your device’s requirements. Whether you need one depends on the voltage rating of your electronics.

 

Step 1: Check Your Device’s Voltage Rating

Look at the label on your charger or power brick and find the line that reads “INPUT: 100–240V” or something similar.

 

If Your Device Says “INPUT: 100–240V”

Great news—your device is dual-voltage and fully compatible with Japan’s 100V power system.
You do not need a voltage converter. You only need a plug adapter for Japan (Type A or B).

Most modern electronics fall into this category, including:

  1. Smartphones and tablets (iPhone, Samsung, iPad, Android devices)
  2. Laptops and chargers (MacBook, Windows laptops, USB-C chargers)
  3. Digital cameras and battery chargers, including mirrorless and DSLR systems
  4. Portable power banks and USB chargers
  5. Bluetooth speakers, earbuds, e-readers, smartwatches, and other low-wattage digital devices
  6. USB charging blocks, which are nearly always dual-voltage
  7. These devices are engineered for worldwide travel and automatically adjust to the voltage in Japan.

 

If Your Device Says “INPUT: 110–120V” or “220–240V” Only

Your device is single-voltage.
If it is only compatible with 220–240V, it will not work properly in Japan, and may fail or become damaged if plugged into a 100V Japanese outlet without a converter.

In this case, you will need a voltage converter to safely use the device in Japan.

This includes certain appliances such as:

  • Specialty electronic tools
  • Older laptop chargers
  • Some household appliances not designed for travel

 

Important Warning for High-Power and Heat-Producing Appliances

High-wattage devices are the most likely to be incompatible, including:

  • Hair dryers
  • Curling irons & straighteners
  • Electric kettles
  • Clothing steamers
  • Travel irons

These appliances:

  • Are often single-voltage
  • Require a large amount of power
  • Can overheat or burn out if used with small, cheap travel converters
  • May even trip hotel circuits if the wattage is too high

For these high-power items, the safest options are:

 

Buy a dual-voltage travel version specifically designed for international trips.Use the appliance provided by your hotel or accommodation (most Japanese hotels supply hair dryers). If absolutely necessary, purchase a high-wattage voltage transformer, though these are heavy, expensive, and not ideal for travel.
