Sockets in Japan

Voltage
230 V → 100 V
Voltage drops from 230 V to 100 V. Dual-voltage gear is fine; single-voltage appliances will underperform rather than break.

Japan is high on every Australian traveller's list, and its power setup is unusual. It uses flat Type A/B pins (like the US), while you carry the Australian Type I plug, so an adapter is essential. Japan also runs on just 100V, the lowest mains voltage anywhere, against Australia's 230V.
