The Okinawa Reversion Agreement (Japanese: 沖縄返還協定, Hepburn: Okinawa henkan kyōtei) was an agreement between the United States and Japan in which the United States agreed to relinquish in favor of Japan all rights and interests under Article III of the Treaty of San Francisco, which had been obtained as a result of the Pacific War, and thus return Okinawa Prefecture to Japanese sovereignty. The document was signed simultaneously in Washington, DC, and Tokyo on June 17, 1971, by William P. Rogers on behalf of United States President Richard Nixon and Kiichi Aichi on behalf of Japanese Prime Minister Eisaku Satō.[1] The document was not ratified in Japan until November 24, 1971, by the National Diet.[1]
