Frequently asked

What type of plug does Japan use?
Japan uses Type A and Type B outlets at 100V, 50Hz.
What's the voltage in Japan?
Japan runs on 100V at 50Hz — that's the low-voltage standard. Dual-voltage devices (most phones, laptops, modern chargers labelled "100-240V") work as-is. Single-voltage devices like hair dryers, curling irons, and travel kettles do not without a converter.
Do I need a travel adapter for Japan?
Only if your home country uses a different plug type. Travellers from any country whose plugs aren't Type A/B will need an adapter. Use the table above or the calculator to check your specific pair.
