How to check your laptop charger
Look for the "Input" rating on the plug, power brick or the handle near the cable:
- 100–240V ~ 50/60Hz – works anywhere in the world with a plug adapter.
- A switch marked 120/230 or 110/220 – dual-voltage: set it to match the country before plugging in.
- 220–240V only – fine in the UK and Europe, but not on Japan's 100V supply.
Plugs in Japan
Yes. You'll need a US-style (type A/B) adapter.
- Type A: Two flat parallel pins (no earth)
- Type B: Two flat parallel pins plus a round earth pin

Common questions
Can I use my UK laptop charger in Japan?
Almost every laptop charger is rated 100–240V (check the small print on the plug or power brick), so it works on the 100V supply in Japan with just a plug adapter. You'll need a US-style (type A/B) adapter.
What voltage is Japan?
100V at 50/60Hz. The UK is 230V at 50Hz.
Do I need a voltage converter for my laptop charger?
No, as long as the label says 100–240V – nearly all do.
