日本国とアメリカ合衆国との間の相互協力及び安全保障条約
In 1962, after the conclusion of the Treaty of Mutual Cooperation and Security between the United States and Japan, the base was returned to the control of the Japanese government and reestablished as a training facility for the post-war Japan Ground Self-Defense Force. It has been home to the JGSDF 34th Infantry Regiment, which has been active in various disaster relief operations throughout Japan since that time.
