Japan Travel Adapters
Type A and Type B • 100 volts • 50/60 Hz
Japan is an island country in East Asia located in the Pacific Ocean east of the Asian mainland. The capital city is Tokyo. Japan is known for its mix of modern cities, historic temples, and natural landscapes that include mountains, forests, and coastlines.
Japan uses mains electricity supplied at about 100 volts. The country has two different power frequencies depending on the region. Eastern Japan, including Tokyo, uses 50 Hz, while western Japan, including Osaka, Kyoto, and Hiroshima, uses 60 Hz. Wall outlets use Type A sockets, and many locations also provide Type B sockets. Travelers from regions that use different plug types should bring a compatible travel adapter. Visitors should confirm that their electronic devices support 100–240V input or use an appropriate voltage converter if necessary.
For the special Japan voltage question, see our Japan 100V ↔ 120V voltage transformer guide.

Plug types are listed because they are encountered in at least some installations. Presence may be partial, legacy, mixed, or situational. A travel adapter, also spelled travel adaptor, changes plug fit only; a voltage converter, sometimes searched as a voltage convertor, is needed only for devices that are not dual voltage. No plug type is excluded due to limited or declining use.
