Yontan Airfield

Yontan Airfield. A former military airbase located on the west coast of Okinawa Island in the Ryukyu Islands. Constructed by the Imperial Japanese Army during the Pacific War, it was a primary objective for Allied forces during the Battle of Okinawa. Following its capture, it became a critical hub for United States Army Air Forces operations against the Japanese archipelago and later served various roles under the United States Air Force before reverting to Japanese control.

History

The airfield's construction was ordered by the Imperial Japanese Army Air Service in 1944 as part of the bolstering of the Japanese archipelago's defensive perimeter. Built largely with forced labor from the local Okinawan population and Korean conscripts, it was intended to support kamikaze and interceptor operations against the advancing United States Navy. The rapid American advance across the Central Pacific made Okinawa Island a strategic linchpin, leading to the monumental Battle of Okinawa in April 1945. The initial assault landings by the United States Marine Corps and United States Army's Tenth Army specifically targeted Yomitan and Kadena Air Base to secure operational airfields.

World War II operations

Captured intact by elements of the 6th Marine Division in the early days of the battle, the airfield was immediately put to use by American forces. It was swiftly repaired and expanded by the United States Army Air Forces' 808th Engineer Aviation Battalion, becoming operational for Allied aircraft within days. The base hosted a wide array of units, including fighters from the 318th Fighter Group and bombers from the 41st Bombardment Group, which conducted strikes against targets in Kyushu, Shanghai, and Formosa. It also served as a vital emergency landing field for B-29 Superfortresses returning from missions over the Japanese archipelago, most famously the damaged aircraft involved in the Doolittle Raid earlier in the war. The airfield was a frequent target for Japanese counterattacks, including raids by Giretsu Kuteitai special forces.

Post-war use

After the Surrender of Japan, Yontan was renamed Yontan Air Base and became a permanent installation under the newly formed United States Air Force as part of the United States Civil Administration of the Ryukyu Islands. During the Korean War, it functioned as a crucial staging and logistics base for operations like the Battle of Inchon and the Hungnam evacuation, supporting units such as the 18th Fighter-Bomber Wing. Its role continued through the Vietnam War, where it served as a transit point for personnel and equipment. The 1971 Okinawa Reversion Agreement between the United States and Japan stipulated the return of the facility, with full administrative control reverting to the Government of Japan in 1972.

Current status

Following reversion, the airfield was closed and the land was returned to civilian use. The majority of the former base grounds were developed into the modern Okinawa Comprehensive Athletic Park, a central venue for the 1996 National Sports Festival of Japan. A small section of the original runway remains visible and is maintained as a historical site. The area also hosts the Yomitan Village Office and the Yomitan Sun Beach, with the surrounding region being a center for Okinawan pottery and other cultural activities. No active military flying operations occur at the site.
