Japanese voltage & plugs — using Japanese electronics abroad
Japan uses 100V and Type A plugs. Find out whether Japanese electronics work in your country and when you need a transformer, with a region-by-region chart.
Electricity in Japan
Japan runs on 100V — the lowest in the world — with Type A plugs (two flat pins). To use Japanese products abroad, check two things: voltage and plug shape.
Will it work in your country?
- If the label says 100-240V, it works worldwide — you only need a plug adapter
- If it says 100V only, you need a step-down transformer — plugging into 230V risks damage or fire
- Most laptops, phone chargers, cameras, and game consoles are 100-240V
- Heat-producing items (hair dryers, rice cookers, heaters) are usually 100V-only and need a high-wattage transformer
Voltage & plugs by region
| Country/region | Voltage | Plug | Japanese 100V products |
|---|---|---|---|
| US & Canada | 120V | A/B | Usually fine as-is (avoid prolonged heavy use) |
| UK | 230V | G | Transformer + adapter required |
| EU | 230V | C/F | Transformer + adapter required |
| Australia & NZ | 230V | I | Transformer + adapter required |
| Singapore & Hong Kong | 220-230V | G | Transformer + adapter required |
| Taiwan | 110V | A/B | Usually fine as-is |
| Middle East (UAE, etc.) | 220-240V | G/C | Transformer + adapter required |
Pre-purchase checklist
- Check the product page for supported voltage (100V-only or 100-240V)
- For consoles and video gear, also check region locks (BD/DVD region codes, broadcast standards)
- Choose a transformer rated above the product's wattage
