Japan → United Kingdom

No. Your Type A and Type B plugs from Japan will not fit United Kingdom's sockets. You'll need a travel adapter.

The voltage in United Kingdom is 230V. This is higher than Japan's 100V. Check if your device supports dual voltage (100-240V).

No, you don't need a voltage converter. The voltage difference (100V to 230V) is safe for most modern devices, especially laptops, phones, and chargers which typically support 100-240V dual voltage.

United Kingdom uses Type G sockets. You will see these socket types in hotels, airports, and public places throughout the country.

Yes, most modern electronics (iPhones, laptops, tablets, cameras) are dual-voltage (110V-240V), so they will work in United Kingdom. Since United Kingdom uses 230V (within the 100-240V range), your device will work fine. You'll need a plug adapter to fit the wall socket.

You can buy a Type G travel adapter online (Amazon, eBay) or at the airport. Look for adapters specifically designed for United Kingdom or universal adapters that include Type G. Check our Amazon link above for the best options.

If you don't use an adapter, your plug physically won't fit into United Kingdom's sockets. Additionally, if the voltage is different (100V vs 230V) and your device isn't dual-voltage, you could permanently damage your device or cause a fire hazard. Always use the appropriate adapter and check voltage compatibility.
