Key Data


Yokota Air Force Base (YAFB) is situated 45km north-west of Tokyo at the foothills of the Okutama mountains in Japan. It is one of the three United States Air Force (USAF) bases in Japan built near the Tokyo metropolitan area.

The base is owned and operated by the USAF. About 14,000 personnel currently residing in the base.

Yokota Air Force Base history

YAFB was built in 1940 by the Imperial Japanese Army. The base was then known as Tama Airfield. Flight test activities of the Japanese Army Air Forces were carried out at the base during the Second World War. The USAF took over the control of Tama Air Field on 4 September 1945. Upon unveiling the air field as a US facility, the airfield was renamed Yokota Air Base in August 1946.

The base was used for bomber, reconnaissance and air defence missions during the military control of Japan between 1946 and 1950. It was utilised for combat missions over North and South Korea during the Korean War. It was also used for battle and air refuelling missions during the Cold War.

The squadrons deployed at the Yokota base were migrated to Kadena and Misawa Air Base in 1971. The headquarters of the Fifth Air Force (5AF) was shifted to the YAFB in November 1974.

The 316th Tactical Airlift Group, a part of the 374th Tactical Airlift Wing (374 TAW), arrived at the base in 1978. The 374 TAW was moved from Clarke Air Base to Yokota Air Base in 1989. It was renamed as 374th Airlift Wing (374 AW) in April 1992 and became a host unit of the base.

The Japanese Government decided to transfer the Japan Air Self Defence Force to the Yokota base in 2005.
