Shape of 100 V and 200 V plug sockets
Although 200 V is used for some appliances, the voltage in Japan is generally 100 V.
Appliances brought from overseas might not be usable at the voltage in Japan. Note that the plug sockets for 100 V and 200 V are different in shape.
The electric frequency is different on either side of the Fujigawa River in Shizuoka Prefecture and Itoigawa City in Niigata Prefecture, with 50 Hz to the east and 60 Hz to the west. Kansai Electric’s service area uses a frequency of 60 Hz.
