Plug adapter or voltage converter?

Two checks: the shape of the plug, and whether INPUT on the label includes 100V.

Flow chart: a plug with two flat pins fits; otherwise bring a Type A plug adapter. INPUT that includes 100V needs no converter.

Figure by japan-japan.com from JNTO: Plugs and Electricity.

  1. Plug: two flat parallel pins fit Japan's Type A outlets. Any other shape needs a plug adapter.
  2. Voltage: read INPUT. A range such as 100-240V includes Japan's 100V.
  3. Frequency: 50Hz in the east, 60Hz in the west. 50/60Hz on the label works in both.

INPUT does not include 100V? JNTO says a device that is not dual-voltage needs a converter to change the voltage.

How to read INPUT on a charger: 100-240V includes Japan's 100V, 220-240V does not. 50/60Hz works in east and west Japan.

50Hz in the east, 60Hz in the west

14 prefectures are on 50Hz, 29 on 60Hz and 4 (Gunma, Niigata, Nagano and Shizuoka) have both. The voltage is 100V on both sides.

Map of Japan's prefectures by frequency: 50Hz in the east, 60Hz in the west, both in Gunma, Niigata, Nagano and Shizuoka.

What JNTO and Japan's power companies say

The official wording on voltage, plugs and where to buy adapters.

JNTO (Japan National Tourism Organization)The voltage used throughout Japan is uniformly 100 volts, A.C. There are two kinds of frequencies in use—50 Hertz in eastern Japan and 60 Hertz in western Japan (including Nagoya, Kyoto and Osaka).JNTO
JNTO FAQPower outlets use Type A plugs.JNTO FAQ
JNTO FAQIf 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

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.

Can I charge my phone on the shinkansen?

Yes, at seats with an outlet. Every seat has one on N700S, W7, E7 and E8, according to the JR companies.

How many visitors to Japan come from 220–240V countries?

73% of 2025 visitors from the top 20 countries and regions: 29,223,624 of 40,182,282 (JNTO).

Where these numbers come from

Mains voltage, frequency and plug shape in Japan and the top 20 visitor countries and regions of 2025, from JNTO and each country's tourism boards, governments and power companies; Japan's 50Hz and 60Hz areas by prefecture from the 10 general transmission and distribution companies; seat outlets on the shinkansen from the JR companies.
