Common questions
Do I need a plug adapter from Japan to United States?
No. Both Japan and United States use Type A/B sockets, so your plugs will fit.
Will my devices work on United States’s voltage?
United States runs at 120V, 60Hz. Dual-voltage chargers (most phones and laptops) are fine; single-voltage devices may need a converter.
