Power sockets

Which types of electrical outlets are used in Japan?

Japan uses electrical outlets of type A and B. As these are the same types of plugs used in the United States, you do not need a travel adapter in Japan.

Mains voltage

What is the Electricity Voltage in Japan?

The voltage in Japan is 100 volts.

The voltage, therefore, is lower than the 120 volts in the United States. This difference means that you have to be cautious when using electrical devices purchased in the United States:

You should read the instruction manual of your device and check at which voltage it is safe to use.

If the voltage stated in the user's manual or on the device's power supply differs from the mains voltage in Japan, you should either not use your device there, or buy a voltage converter before departing.

Utility frequency

What is the utility frequency in Japan?

The utility frequency in Japan is not standardized. Depending on the region, sockets in Japan supply electricity at 50 or 60 Hertz.

The frequency, therefore, is sometimes the same as in the United States. That's why it is safe to use all your electric appliances in Japan.
