Airport Closure Information

Last updated: Nov 21, 2025
Closure Date

August 1945. The airfield was abandoned immediately following the surrender of Japan, which marked the end of World War II.

Reason for Closure

Military Demobilization. Asajino Airfield was an Imperial Japanese Army Air Force base. With the defeat and subsequent demilitarization of Japan after WWII, all military installations of this nature were decommissioned. The airfield's operational purpose ceased to exist, and it was abandoned and dismantled.

Current Status

The site has been entirely converted into agricultural land, primarily used as pasture for dairy farming and known locally as the Asajino Daiichi Farm (浅茅野第一農場). While all buildings and military infrastructure have been removed, the faint X-shaped outline of the two former runways is still clearly visible in satellite imagery. A peace monument (平和の碑) and historical markers have been placed near the site by the town of Hamatonbetsu to commemorate its history and pray for peace.

Historical Significance

Constructed by the Imperial Japanese Army between 1942 and its completion in 1944, Asajino Airfield was a major strategic air base during World War II. Its primary role was to serve as a forward base for fighter aircraft to intercept American bombers and defend the northern territories of Japan, including Hokkaido and the Kuril Islands. It was one of the largest airfields in Hokkaido at the time, featuring two intersecting runways. The base was a critical component of Japan's northern air defense network during the final phase of the Pacific War.

Reopening Prospects

None. There are no plans or prospects for reopening the airfield. The land has been privately owned and used for agriculture for over 75 years, and there is no modern strategic or commercial need for an airport at this specific location, especially with Wakkanai Airport (RJCW) serving the region.
