JNTO FAQ JNTO FAQ If you are traveling from overseas, you may need a plug adapter.
JNTO FAQ JNTO (Japan National Tourism Organization) Certain types of electrical appliances such as dual-voltage hair dryers, travel irons and shavers should work wherever you are in Japan. However, in other cases, a step-down transformer is required to convert the voltage.
JNTO JNTO (Japan National Tourism Organization) In urban areas, it is relatively easy to find devices such as conversion plugs and transformers. They are sold in electronics quarters such as Tokyo's Akihabara and Osaka's Nipponbashi, or at major home appliance mass retailers such as Yodobashi Camera or Bic Camera.
JNTO Kansai Electric Power (English page) Although 200V has been implemented for some appliances, basically the voltage in Japan is 100V.
Kansai Electric Power Kansai Electric Power (English page) 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.
Kansai Electric Power Panasonic アジア 日本 100 50/60 A・B
Panasonic In English: Asia, Japan: 100V, 50/60Hz, plug types A and B.
Frequently asked questions What plug type does Japan use? Type A, with two flat parallel pins (JNTO). Panasonic lists Type A and B for Japan.
What is the voltage in Japan? 100V throughout Japan (JNTO). Kansai Electric Power adds that some appliances use 200V.
Is Japan 50Hz or 60Hz? Both. Eastern Japan uses 50Hz and western Japan, including Nagoya, Kyoto and Osaka, uses 60Hz (JNTO). Gunma, Niigata, Nagano and Shizuoka have areas on each.
Is Japan's plug the same as in the US? For two-prong plugs, yes. Thailand's tourism authority and Beijing's government both describe the flat two-pin plug as US and Japan style. Japan uses 100V; the US 110/120V.
Do I need a voltage converter for Japan? Only for a device whose INPUT does not include 100V and that is not dual-voltage (JNTO). Chargers rated 100-240V work without one.
Where can I buy a plug adapter in Japan? JNTO names Akihabara in Tokyo, Nipponbashi in Osaka, Yodobashi Camera and Bic Camera.
