Plug types in Japan
- Type A: two flat parallel pins
- Type B: two flat pins plus a round grounding pin
Eastern Japan (including Tokyo) runs at 50Hz and western Japan (including Osaka) at 60Hz; modern chargers handle both. Many older sockets are two-pin only, so three-prong plugs may need a small adapter.
Will my devices work on 100V?
Check the small print on your charger. If it says INPUT: 100–240V, it works anywhere with just a plug adapter. Most phone, laptop and camera chargers are dual-voltage. Hair dryers, curling irons and some kitchen gadgets are often single-voltage and can be damaged on the wrong voltage.
FAQ
What plug type does Japan use?
Japan uses Type A and Type B plugs, with a standard voltage of 100V at 50/60Hz.
Do I need a voltage converter for Japan?
Usually not for phones, tablets, laptops or cameras, because their chargers are almost always rated 100–240V. Single-voltage appliances like some hair dryers and straighteners may need a converter or a dual-voltage model.
What's the difference between a plug adapter and a converter?
An adapter only changes the plug shape. A converter changes the voltage. Most travelers only need an adapter.
Is a universal travel adapter worth it?
If you visit more than one region, yes. One universal adapter covers most plug types, and many have USB ports built in.
