Yokota Air Base (横田飛行場 Yokota Hikōjō?), (IATA: OKO, ICAO: RJTY) is a United States Air Force base in the city of Fussa, one of 26 cities in the Tama Area, or Western Tokyo.

The base houses 14,000 personnel. The base occupies a total area of 136,413 m2 (1,468,340 sq ft) and has a 3,353 m × 61 m (11,001 ft × 200 ft) runway. Among its facilities are the broadcast center for the American Forces Network Tokyo radio service and a detachment of PACAF's Band of the Pacific.


The host unit at Yokota is the 374th Airlift Wing and is currently used for airlift missions throughout East Asia. The 374th includes four groups: operations, mission support, maintenance and medical. Each group manages a various number of squadrons in order to carry out the wing's mission.

It is not uncommon to see a C-5, KC-10, DC-8, C-17, L-100, civilian charter airline aircraft (Omni International, North American Airlines, World Airways, Ryan International, etc.) and cargo 747s on the Transient Aircraft ramp.

  • 374th Maintenance Group
    The 374th Maintenance Group maintains C-130H1, C-12 and UH-1N aircraft supporting intratheater airlift and distinguished visitor transport for Pacific Air Forces.
  • 374th Mission Support Group
    The 374th Mission Support Group is responsible to the 374th Airlift Wing Commander for command, control and direction of support activities to 374 AW and 32 tenant units to include HQ US Forces Japan and Fifth Air Force.

The newly renovated Air Mobility Command (AMC) Passenger Terminal is on the main part of the base next to the flightline. It is a 5- to 7-minute walk from the Kanto Lodge (see below) and offers Space-Available flights to various destinations in PACAF such as Alaska, Guam, Hawaii, Korea, Okinawa, Singapore, as well as the Contiguous United States.


The facility which houses Yokota Air Base was originally constructed by the Imperial Japanese Army in 1940 as Tama Airfield, and used as a flight test center. During World War II Yokota became the center of Japanese Army Air Forces flight test activities and the base was the site of the first meeting between Japanese and Italian wartime allies.

Tama was first identified by United States military forces in November 1944 by a 3d Reconnaissance Squadron F-13 Superfortress photo-reconnaissance aircraft, flying from Tinian in the Marianas. It was identified as being associated with a nearby Musashino-Nakajima aircraft manufacturing plant. Along with the Showa Air Base to the northwest, and Tachikawa Air Base to the east, it was compared to the aircraft development complex of the USAAF Wright-Paterson Field in Ohio. According to the USAAF intelligence at the time, the three bases conducted all IJA flight testing. In the spring of 1945, XXI Bomber Command attacked the base eight times along with the aircraft manufacturing plant, but each time heavy clouds forced the bombers to attack secondary targets. The Nakajima plant was finally attacked in April 1945, but the Tarma airfield never was bombed.

Postwar years[]

With the end of hostilities and the Japanese surrender in September 1945, a detachment of the United States Army 1st Cavalry Division arrived at the base on 4 September. The airfield's buildings were largely intact, and some 280 of the IJA's most modern aircraft were discovered in hangars. The 1st Cav named the facility Fussa Army Airfield, then renamed it Yokota Army Airfield at the end of September.

The initial USAAF use for the base was for airlift operations when the 2d Combat Cargo Group arrived with four C-47 Skytrain squadrons. When the old runway deteriorated under heavy usage, the runway was repaired and Yokota supported operations of the Douglas A-26 Invader-equipped 3d Bombardment Group by August 1946. Additional construction during the 1940s and 1950s was completed and the base reached its current size around 1960.

On the occasion of extension, the course of Hachiko Line and national highway Route 16 was changed, and Itsukaichi highway was divided.

During the initial postwar occupation years, Yokota hosted the following known USAAF/USAF units:

  • 20th Combat Mapping Group (October 1945 - April 1946) (F-7 (B-24) Liberator)
  • 8th Reconnaissance Group (June 1946 - October 1947) (F-7 (B-24) Liberator)
  • 71st Reconnaissance Group (February 1947 - April 1949)
    (RB-17, RB-29, RF-51, RF-61, and RF-80)

These units performed photographic reconnaissance and mapping of Japan and South Korea.

  • 6th Night Fighter Squadron (1946–47) (P-61A/B)
    Inactivated and personnel, mission and equipment transferred to 339th Fighter Squadron (347th Fighter Group) with F-82F/G Twin Mustangs at Nagoya AB Japan.
  • 3d Emergency Rescue Squadron (July 1947 - April 1950) (SB-17G)
    Flew modified B-17G bombers equipped under their bellies with a 27-foot boat (termed the A-1) that could be dropped by parachute and which contained enough food, water, and clothing for twelve survivors to last for about twenty days in the ocean.

Korean War[]

During the Korean War, Yokota was used for combat missions over North and South Korea. Known units based there were:

  • Bombardment units
    • 325th, 326th, 327th Bombardment Squadrons (92d Bombardment Group) (July - October 1950)
      Deployed squadrons from Spokane AAFld (later, Fairchild AFB), Washington. Flew B-29 Bombing missions over North Korea.
    • 98th Bombardment Wing (343d, 344th, 345th Bomb Squadrons) (August 1950 - July 1954)
      Group, then Wing deployed from Spokane AAFld (later, Fairchild AFB), Washington. Flew B-29 Bombing missions over North Korea. Two after arriving at Yokota, the squadrons a bomb mission against marshalling yards at Pyongyang, North Korea. The 98th BG engaged primarily in interdiction of enemy communications centers but also supported UN ground forces. Interdiction targets included marshalling yards, oil centers, rail facilities, bridges, roads, troop concentrations, airfields, and military installations.
  • Reconnaissance units
    • 31st Strategic Reconnaissance Squadron, Photographic (July–August 1950)
      Flew combat missions to provide FEAF Bomber Command with target and bomb-damage assessment photography.
    • 91st Strategic Reconnaissance Squadron, Medium, Photographic (December 1950 - December 1954)
      Assigned to 407th Strategic Fighter Wing (1953–54) See 91st Intelligence Squadron
      Absorbed the personnel and resources of the 31st Strategic Reconnaissance Squadron in Japan. Using RB-29, RB-45, RB-50 and RB-36 aircraft, it performed target and bomb-damage assessment photo and visual reconnaissance for FEAF Bomber Command, flew other special photographic missions, and conducted electronic "ferret" reconnaissance to determine frequency, location, and other characteristics of enemy ground radar. The squadron also performed shipping surveillance over the Sea of Japan near the Siberian coast and leaflet drops over North Korea. Beginning in late 1952, rotating aircrews of the Philippine-based 581st Air Resupply and Communications Wing augmented the 91st SRS in flying leaflet missions.
    • 512th Bombardment Squadron (January - August 1950)
      Operated the B/RB/WB-29 aircraft and flew weather reconnaissance missions.
    • 56th Weather Reconnaissance Squadron (September 1951 - July 1972)
      Replaced the 512th Bomb Squadron in their weather reconnaissance mission. They operated WB-29, WB-50, WC-135B and RB-57 aircraft used to sample airborne nuclear debris as well as weather patterns in the Pacific.
      • In fact, the 56th was first the 56th Strategic Recon Squadron. It became the 56th WRS later. And, for several years the only aircraft were modified B-29s.

About 1956 the B-29's began to be replaced with B-50's, and the unit continued to fly two missions a day, plus flying into any typhoons in the South Pacific. In 1956 the 56th lost a plane coming back from a mission, as it crashed into a hill not far from the base. All on board were killed.

Cold War[]

With the hostilities in Korea ending in 1953, Yokota Air Base returned to a peacetime Cold War status. Two major wings were stationed at the base during the 1950s, the 67th Reconnaissance Wing (1956–60) flying RF-80s, RF-84s and lastly RF-101s. The 35th Fighter-Interceptor Wing (1954–57) flew F-86 Sabres from the base. A Tactical Air Command air refueling unit, the 421st Air Refueling Squadron Flew KB-29s,and later KB-50Js from Yokota from 1953-65. All of these units were under the command of the 41st Air Division.

The 35th TFW was reassigned in 1957 and the 67th TRW in 1960. Worldwide DOD Budget restrictions in the late 1950s caused several PACAF wings based in Japan to be reassigned or inactivated. These tactical fighter units were replaced by the Martin B-57 equipped 3rd Bombardment Wing where it trained in bombardment, reconnaissance and aerial refueling operations. The Air Defense Command 40th Fighter-Interceptor Squadron (December 1961 - May 1962) equipped with the Convair F-102 Delta Dagger stood an air defense mission.

The 6102d Air Base Wing assumed host unit status for the base, being replaced by the 441st Combat Support Group in 1964.

The Vietnam War resulted in an increased combat and airlift aircraft presence at the base. Yokota was used for ferrying B-52s to Southeast Asia along with being a base for US-based deployed F-105 Tactical Fighter Squadrons (35th, 36th, 80th). The 610th Military Airlift Support Squadron (1966–78) was created by Military Airlift Command to service the large increase in transiting airlift. The 65th Military Airlift Support Group (1969–71) was a headquarters organization for MAC airlift support squadrons in the Pacific and Far East.

The F-105 squadrons deployed frequently to USAF-operated bases in Thailand to fly combat missions over North and South Vietnam, and to South Korea for alert missions. Initially the fighter squadrons were under the command of the 41st Air Division, shortly after reassigned to the 6441st Tactical Fighter Wing, activated in April 1965 to control the F-105 squadrons after their parent organization, the 8th Tactical Fighter Wing, relocated to George Air Force Base, California, to become a McDonnell Douglas F-4 Phantom II unit. With the reassignment of the 347th Fighter Wing to Yokota in 1968, the 347th assumed responsibility for all tactical fighters until its reassignment to Kunsan AB, South Korea, in March 1971.

In 1971, all combat squadrons were transferred to Kadena and Misawa Air Base and Yokota became a non-flying station hosted by the 475th Air Base Wing. The 475th had no numbered flying squadrons, but operated a few T-39 Saberliners and UH-1 helicopters, along with supporting transient MAC cargo and passenger aircraft. Assigned flying squadrons returned to Yokota in 1975 when the 345th Tactical Airlift Squadron was assigned with its C-130Es.

Headquarters, Fifth Air Force was transferred to Yokota on November 11, 1974, being transferred from Fuchu AS, Japan.

Post-Cold War[]

In 2005, the Japanese government announced that the headquarters of the Japan Air Self-Defense Force would be moved to Yokota.

The Tokyo Metropolitan Government has advocated opening Yokota to civilian flights, as a method of relieving traffic at Haneda and Narita Airport.


Tents used to house Operation Tomodachi troops

In April 2010 Colonel Frank Eppich, the United States Air Force commander of base, banned screenings of the film The Cove at the base theater. A base spokesman said that The Cove was banned because using a base venue to display the film could be seen as an endorsement of the film. The spokesman added, "We have a lot of issues with Japan...and anything done on an American base would be seen as an approval of that event."[3]

Personnel and aircraft from the base assisted with Operation Tomodachi following and during the March 2011 Tōhoku earthquake and tsunami and Fukushima I nuclear accidents. The base also served as an important hub for airlifted assistance during the disaster recovery efforts. During the crisis, around 600 American family members voluntarily departed the base for locations outside Japan.[4]
