A Guide To Electricity
Voltage and frequency are different in Japan.
Japan’s electricity runs on different voltage and frequency compared to other countries.
To ensure correct and safe use of electrical appliances, we will explain about the electricity system in Japan.
- Map of regional frequency differences
- Shape of plug sockets for 100V and 200V
The Kansai Electric Power Company supplies electricity at 100V/60Hz.
Although 200V has been implemented for some appliances, basically the voltage in Japan is 100V.
Appliances brought from overseas might not be used at the voltage in Japan. Note that the plug sockets for 100V and 200V are different in shapes.
The electric frequency is different on either side of the Fujigawa River in Shizuoka Prefecture and Itoigawa City in Niigata Prefecture, with 50Hz in the east and 60Hz in the west. The frequency in Kansai Electric’sservice area is 60Hz.
- Televisions and radios may be used.
- Refrigerators and air-conditioners will work but less efficiently.
- Washing machines and microwave ovens may not be used.
Some appliances cannot be used on different frequencies.
Be careful of using electrical appliances which may not be used in a different frequency area.
• Appliances which may be used in either area
• Appliances which may be used in either area but with lower efficiency
Refrigerators, Electric fans, Air-conditioners, etc.
• Appliances which cannot be used in a different frequency area
Washing machines, Microwave ovens, Fluorescent lights (except inverter-types), Clothes driers, etc.
※ These appliances are shown as general examples. There are exceptions, so it is best to check the operating manual or consult with the manufacturer directly.
