🇯🇵Power in Japan.

Japan uses Type A and B outlets identical to North America, so US and Canadian travelers can plug in without any adapter. But Japan's electrical system has a fascinating quirk: it runs on just 100V, the lowest voltage of any developed nation.

Your devices will work fine but may charge about 10-15% slower than at home. Even more unusual, Japan is split between two frequencies: eastern Japan (Tokyo, Yokohama, Sendai) runs on 50Hz, while western Japan (Osaka, Kyoto, Hiroshima) runs on 60Hz.

This dates back to the 1890s when Tokyo imported German 50Hz generators and Osaka imported American 60Hz ones. Most modern electronics handle both frequencies automatically.

When working remotely from Tokyo's bustling cafes or Kyoto's traditional accommodations, secure your internet connection on public WiFi networks. Having mobile data ready when you land at Narita or Haneda helps with navigation through Japan's complex train systems and instant translation of station signs.

§ 06 · Type A plugs
A

The plug used in Japan.

Eastern Japan (including Tokyo, Yokohama, and northern regions) operates on 50Hz frequency, while western Japan (Osaka, Kyoto, Hiroshima, and southern areas) uses 60Hz. The dividing line roughly follows the Fuji River and Itoigawa-Shizuoka geological fault. Most hotels and public spaces use standard Type A outlets, though some newer buildings include Type B grounded outlets for safety.
