US administration of the Ryukyu Islands (centered on Okinawa) separated from Japan after WWII — the United States Military Government of the Ryukyu Islands (1945-1950), then the United States Civil Administration of the Ryukyu Islands (1950-1972) — overseeing a local Government of the Ryukyu Islands under American veto.
Reverted to Japanese sovereignty on 15 May 1972 under the Okinawa Reversion Agreement, though major US military bases remained on the islands.
Covers the US military governments' and civil administration's rule over Okinawa from 1945 to the 1972 reversion.
