What sources of information should foreigners use to work and build a career in Japan?
For rules such as status of residence and the notification, certification, registration and licensing of schools and organizations, the information published by public bodies such as the Immigration Services Agency of Japan, MEXT and OTIT is the authoritative source. When choosing a school or support organization, first check that it is on the official lists, then compare reviews and ratings from people who actually studied or worked there.
