USACC-J, Fort Buckner, Okinawa

The United States Army Communications Command - Japan (USACC-J), headquartered at Fort Buckner, Okinawa, played a vital role in managing and operating military communications for U.S. Army forces in the Pacific region. Established during the Cold War era, USACC-J provided secure and reliable communications support for joint and combined operations, particularly during periods of heightened regional tension. As a subordinate of the U.S. Army Communications Command, the unit oversaw signal operations, maintenance, and technology integration across Okinawa and mainland Japan. Over time, USACC-J’s mission evolved with advances in communications technology, contributing significantly to U.S. military readiness and coordination throughout the Asia-Pacific until its functions were reorganized under new commands.
