Travel Plug Adaptor for Japan

The electrical sockets used in Japan are type A and type B. These are 2 variants of the same socket - one earthed (with an earth pin) and the other unearthed. You will therefore need a UK 3 pin to type A/B plug adaptor in order to connect your devices.

Please be aware that whilst a travel adaptor will allow you to physically plug a UK plug into a different socket it will not change the voltage or frequency of the supply.

Warning triangle Voltage - The mains voltage in Japan is 100 V which is incompatible with most UK appliances (UK voltage is currently specified as 230 V +10% / - 6%). Check any appliances that you wish to use carefully to see what voltage is specified. Items such as laptops will often specify "100 - 240V" either on the equipment or the power supply (if it has one). If not then you will need a transformer to operate your appliance.

Frequency - Both 50Hz and 60 Hz are in use in Japan . The UK operates at 50 Hz so if the area that you are travelling to runs at this frequency it will not cause any issues. If the area that you are going to operates at 60 Hz it makes little practical difference as most travel appliances will run at either frequency. Some items with motors, such as hairdryers and some clocks will run a little faster than intended but it is not likely to be problematic. Check your device - it may say 50/60 Hz which indicates that it is compatible with either frequency. If you are in doubt or have expensive equipment check with the manufacturer first as some equipment may be damaged by running on an incorrect frequency.

Special considerations - "Eastern Japan 50 Hz (Tokyo, Kawasaki, Sapporo, Yokohama, and Sendai); Western Japan 60 Hz (Okinawa, Osaka, Kyoto, Kobe, Nagoya, Hiroshima). Older buildings have non-polarized sockets, in which case American polarized plugs (one prong wider than the other) would not fit. Many buildings do not have the ground pin. Sockets and switches fit in American-sized standard boxes."
