About electricity in Japan

Japan uses 100V with both 50Hz (east of the Fuji River, including Tokyo) and 60Hz (west, including Osaka). Sockets are Type A and B.

Grid & history

Japan’s split-frequency grid is a 19th-century legacy: Tokyo bought German 50Hz generators while Osaka bought American 60Hz ones, and the two never unified. Frequency converters now straddle the boundary. Post-Fukushima, nuclear is partially restarting while gas and coal still dominate.

Availability

Reliability is very high in cities. Typhoons and earthquakes cause regional outages.

Sockets & hotels

Many older sockets are ungrounded Type A, while newer buildings have grounded Type B for high-draw appliances.

Nuclear share fluctuates as more reactors return to service.

Practical tips

US flat-pin plugs (Type A) fit Japanese outlets directly, so most travellers do not need an adapter.
Voltage is 100V, which is slightly lower than the US 120V. Modern chargers handle this without issue, but heating appliances may run weak.
If your gear is frequency-sensitive (clocks, some motors), check whether you will be in 50Hz or 60Hz territory.
