Operational history

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.

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 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)
    Deactivated and redesignated as 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:

  • Fighter units
    • 27th Fighter-Escort Wing (November - December 1950)
      Flew F-84E Thunderjets on armed reconnaissance, interdiction, fighter escort, and close air support missions.
    • 35th Fighter-Interceptor Wing (April - August 1950)
      Flew Lockheed F-80Cs on air defense missions.
    • 339th Fighter-All Weather Squadron (April - August 1950)
      Attached to 35th Fighter-Interceptor Wing and flew F-82F/G Twin Mustang missions over South Korea during the first few months of hostilities.
  • 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-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 1957 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 1957 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 deactivated. 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 6144th TFW (both temporary units) 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 6441st Tactical Fighter Wing, activated in July 1964 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.

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."


Friendship Festival

Each year in August, Yokota Air Base opens the gates to the Japanese community for its annual Friendship Festival. For two days, local residents can learn about Yokota Air Base. Food and events are provided for all ages. Roughly 200,000 visitors show up each year, although non-Japanese visitors may be turned away from the gates for security reasons.

For those 2 days, visitors are able to examine many types of aircraft and even tour some of the large cargo planes from inside.

Hotels and lodging

Kanto Lodge - DSN (315) 224-2000

The Kanto Lodge is one of PACAF's largest hotel operations. Each year, over 130,000 personnel are housed in the Kanto Lodge's eleven on-base facilities. The new, 125-room Temporary Lodging Facility (TLF) opened in the summer of 2001 .


The Department of Defense Education Activity operates schools at Yokota for children of personnel assigned to the base.

  • Joan K. Mendel Elementary School (formerly known as Yokota East Elementary School)
  • Yokota West Elementary School
  • Yokota Middle School: School Dedication Ceremony took place on 13 June 2000. YMS initial year began with only grades 7 and 8, with the upstairs specialty wing housing High School classes until construction modifications to YHS were competed. Class officially began August 2000.
  • Yokota High School

Higher educational opportunities for those in the military and working for the Department of Defense, as well as for family members at Yokota are available through several contracted academic institutions. For example:

  • The Asian Division of University of Maryland University College (UMUC)[1]

The base was the setting of Almost Transparent Blue, a best-selling novel written by Ryu Murakami and published in 1976. It is also the setting of parts of The Yokota Officers Club : A Novel by Sarah Bird.
