Common questions
Do I need a plug adapter from China to Japan?
Yes. Japan uses Type B sockets, which China plugs do not fit, so pack a suitable adapter.
Will my devices work on Japan’s voltage?
Japan runs at 100V, 50/60Hz. Dual-voltage chargers (most phones and laptops) are fine; single-voltage devices may need a converter.
