Japan-U.S. Friendship Commission: “The Japan-U.S. Friendship Commission is a U.S. federal government agency. The Commission was established as an independent federal government agency by the United States Congress (P.L. 94-118)  in 1975 to strengthen the U.S.-Japan relationship through educational, cultural, and intellectual exchange. The Commission is a grant-making agency that supports research, education, public affairs and exchange with Japan. Its mission is to support reciprocal people-to-people understanding, and promote partnerships that advance common interests between Japan and the United States. The Commission also serves to maintain expertise on Japan Studies throughout U.S. academic and professional institutions. It generally does not operate its own programs. It supports academic and non-profit organizations that conceptualize and execute U.S.-Japan training, research and exchange programs.”
