Yokota AB opened in 1940, under Japanese authority as Tama Air Field. Yokota was used as a test facility for the Japanese Imperial Army. In 1945, Tama Air Field became Yokota AB. The 374th Air Wing formed in Australia in 1942, and was among the first to fight in Korea in 1950. The 374 then served in Vietnam from the 1960's to the 1970's, and arrived in Yokota in 1989.
Yokota is both a US and UN base, and is primarily a UNC airlift hub. Yokota Air Base serves as the host base for Headquarters, United States Forces Japan and Fifth Air Force. The 374th Airlift Wing provides tactical airlift, medical evacuation, and distinguished visitor airlift for the western Pacific, while serving as a key strategic airlift hub for the entire theater.
