Will your plug and devices work?
Same Different
IEC World Plugs. Similar voltage means the 100-127V range, like Japan.
Most phone, laptop and camera chargers accept 100-240V, so they work in Japan once the plug shape fits. The input rating on the charger or device shows whether 100V is included.
Devices made only for 220V do not run properly on Japan’s 100V and need a transformer.

Tokyo is on 50Hz; Osaka, Kyoto, Fukuoka and Okinawa are on 60Hz. Chargers and most electronics work on both, and only appliances marked for 50Hz or 60Hz alone depend on the region.
