The Korjo Travel Adaptor Plug Japan is for use in Japan*. It can also be used in USA*, Canada*, and several other countries using a flat 2 pin socket. This adaptor only accepts 2 pin** Australian and New Zealand appliances. *Note: Adaptors do not convert voltage - Japan, USA, and Canada are 110V countries - check that your devices are compatible with 110V, or you may need a converter or transformer. ** This adaptor only accepts 2 pin Australian / New Zealand appliances. If you have 3 pin products, we suggest that you take the KA EU adaptor, but be aware that you will probably need to purchase another local adaptor at your destination, to convert from the KA EU pins to the Japanese 2 straight pins. (Australian Electrical Standards do not allow us to manufacture an adaptor that converts a 3 pin earthed plug into a 2 pin, non-earthed plug).
