FAQ

Do Australia plugs work in Japan?

No — Australia Type I plugs don't fit Japan Type A/B sockets. You need a plug adapter.

Not safely if it's single-voltage. Japan runs 100V vs Australia's 230V — use a dual-voltage dryer or a converter.

Is the voltage different between Australia and Japan?

Australia is 230V and Japan is 100V. That difference matters for single-voltage devices.
