The short answer

Japan uses plug types A, B at 100 V, 50/60 Hz. US plugs fit, so most US travelers need no adapter.

Japan uses type A and B plugs, the same flat-pin shapes as the US and Canada, at 100 V. Most American chargers and small devices work in Japan without an adapter or converter.

What you need, by where you're from

"Converter" applies only to single-voltage devices. Chargers marked 100-240V need an adapter at most.

Adapters for Japan

Two-prong US plugs fit as they are. For three-prong plugs in two-slot outlets, a three-to-two prong adapter from any hardware store is enough.

Visiting several countries?

A universal adapter covers types A, C, G and I. It won't fit Switzerland, India or South Africa well.

Worth knowing before you go

  • Many Japanese outlets are two-slot only, with no ground hole. A three-prong US plug needs a small three-to-two prong adapter.
  • Some older outlets have two slots of the same size, so a polarized US plug (one blade wider than the other) won't go in. The same three-to-two prong adapter usually solves this.
  • Eastern Japan, including Tokyo, runs at 50 Hz; western Japan, including Osaka and Kyoto, at 60 Hz. Chargers don't care; some clocks and older motorized devices do.
  • At 100 V, US hair dryers and straighteners run a little cooler than at home but work. Visitors from the UK, Europe or Australia need a type A adapter and should check their devices accept 100 V.
  • Eastern Japan (including Tokyo) runs at 50 Hz and western Japan (including Osaka and Kyoto) at 60 Hz. This only matters for devices with motors or clocks.

Frequently Asked Questions

Do I need a plug adapter for Japan from the US?

Not for two-prong plugs. Pack a three-to-two prong adapter for three-prong plugs, because many Japanese outlets have no ground hole.

Will my US hair dryer work in Japan?

Usually, yes. Japan runs at 100 V against 120 V in the US, so a US dryer works but runs slightly weaker. No converter is needed.

What adapter do I need for Japan from the UK or Europe?

A type A adapter. Also check the device label accepts 100 V; most phone and laptop chargers (100-240V) do.
