USARYIS HQS OKINAWA

**USARYIS HQS Okinawa** (United States Army Ryukyu Islands Headquarters, Okinawa) was established following World War II as the primary administrative and operational command for U.S. Army forces in the Ryukyu Islands, including Okinawa. Activated in the late 1940s, USARYIS HQS managed base operations, logistics, and defense during the postwar occupation and throughout the early Cold War period. The unit played a key role in supporting regional security, facilitating military construction, and coordinating with local Okinawan authorities. In 1972, with the reversion of Okinawa to Japanese administration, USARYIS was inactivated and its responsibilities transferred to the newly formed U.S. Army, Japan.
