We are sorry, but tokens are only intended for use within Japan. We cannot guarantee that tokens will operate correctly if used overseas. However, because tokens are not connected to any kind of network, there is no technical reason why they could not be used outside of Japan. Any use of a token overseas must be at the customer's own risk.
Also, please note that some countries and regions have restrictions about importing or using tokens. Please check with the embassy of the country you intend to visit before your trip.
