Plug fit
Adapter required
UK Type G plugs do not fit Type A or Type B sockets directly.
Voltage
Check your appliance
Japan uses 100V, while the UK uses 230V. Check the voltage on your appliance before you plug it in. A single-voltage UK appliance may need a suitable voltage converter.

Will my UK devices work in Japan?
- Many phone, tablet and laptop chargers are marked 100–240V, 50/60Hz. If yours is, it should normally work with Japan's electricity supply. You will still need a plug adapter.
- Hairdryers, straighteners and other appliances marked for one voltage only need extra care. Check the voltage on the label before you use them.
- Japan uses 50Hz in the east and 60Hz in the west. Some appliances with motors, timers or clocks can be affected by the difference.
Using UK plugs in Japan
A travel adapter changes the plug shape so your UK plug can connect to a Japanese socket. It does not change Japan's 100V electricity supply.
Check the voltage on your appliance before you travel. Devices marked 100–240V, 50/60Hz should normally work with a suitable adapter, but single-voltage UK appliances need checking.
Common questions
Do I need a plug adapter for Japan from the UK?
Yes. Japan uses Type A and Type B sockets, so your UK Type G plug will not fit directly. Take a UK-to-Japan travel adapter.
Do I need a voltage converter in Japan?
Possibly. Japan uses 100V, while the UK uses 230V. Devices marked 100–240V should normally work without a voltage converter, but a single-voltage UK appliance may not. Check the label before you plug it in.
Can I charge my phone or laptop in Japan?
Usually, yes. If the charger is marked 100–240V, 50/60Hz, it should normally work in Japan with the correct plug adapter.
Is the electricity supply the same everywhere in Japan?
The voltage is 100V nationwide, but the frequency differs. Eastern Japan uses 50Hz and western Japan uses 60Hz. Most modern chargers handle both, but appliances with motors, timers or clocks may need checking. Type A sockets are the most common, while three-pin Type B sockets are less common.
