Thought this info on the Japanese Exchange Teaching program might be useful:

"Each year the JET Programme, with the aid of the Japanese Ministry of Foreign Affairs, recruits thousands of new participants to come to Japan and experience a new and unique way of life. Participants are assigned to be either Assistant Language Teachers (ALTs) who provide language instruction in elementary, junior and senior high schools; Coordinators for International Relations (CIRs) who work in communities on international exchange activities; or Sports Exchange Advisors (SEAs) who promote international exchange through sports.

Participants are placed with local government organisations throughout Japan in every imaginable locality, including large cities, small and medium-sized towns, and rural farming and fishing villages."

If you want any more info on it please let me know
