Critical Power Guide for Japan (2026)
The electrical standard in Japan is unique. It uses Type Type A/B (100V), which is not compatible with most global universal adapters unless they are specifically designed for it.
Why Japan is Different
Unlike standard Europlugs, Type Type A/B (100V) has a specific grounding pin alignment. For example, in Switzerland (Type J) or Brazil (Type N), the pins look like European ones but are arranged in a hexagon or specific offset that prevents standard round plugs from fitting safely.
Voltage Safety (Official IEC Data)
According to the International Electrotechnical Commission (IEC), Japan operates on 100V. View Official IEC World Plug Map.
What to Buy
- Do NOT force it: Forcing a Type C plug into a Type Type A/B (100V) socket can damage the internal shutters.
- Certified Adapters: Ensure your adapter is grounded if you are using a laptop or medical device (CPAP).
