To drive a car in Japan, you can either obtain an international driver’s license overseas before arriving in Japan or transfer your overseas driver’s license to a Japanese driver’s license. An international driver’s license is valid for one year after entry into Japan or until the international driver’s license expires, whichever comes first. You will not be able to renew your international driver’s license in Japan. To continue driving in Japan after that, you will need to transfer your regular overseas driver’s license, if it is still valid, to a Japanese driver’s license.
