Power Plugs in Japan
Japan uses Type A and B outlets identical to North America, but runs on a unique 100V system - the lowest voltage of any developed nation. The country is also split between 50Hz (eastern Japan including Tokyo) and 60Hz (western Japan including Osaka). While US and Canadian plugs fit without adapters, Japan's cash-based society and unique infrastructure make it unlike anywhere else.

Complete Guide to Power Plugs in Japan
Japan uses Type A and Type B power plugs and electrical outlets. The standard voltage is 100V with a frequency of 50Hz. This is similar to North American standards, making it easier for US and Canadian travelers.
Do You Need a Travel Adapter for Japan?
Japan uses plug types that may be compatible with your devices, but we still recommend carrying a universal travel adapter for convenience.
Voltage Converter vs. Plug Adapter
It's important to understand the difference: a plug adapter only changes the physical shape of your plug to fit Japan's outlets, while a voltage converter actually changes the electrical current. Japan's 100V is compatible with most devices.
Tips for Travelers to Japan
- Your US/Canadian plugs fit, but Japan's 100V means devices charge about 15% slower than at home
- Eastern Japan (Tokyo) runs 50Hz, western Japan (Osaka/Kyoto) runs 60Hz - most modern devices handle both automatically
- Many budget hotels and traditional ryokans have limited outlets - a small power strip is invaluable
- Train station lockers and convenience stores (konbini) often have charging spots - useful in a pinch
