Susaki Tatsumi Airfield

The primary reason for closure was the end of World War II and the subsequent demilitarization of Japan. The airfield was a military facility for the Imperial Japanese Navy, and with Japan's surrender, its military installations were dismantled. Following the war, the land was repurposed for extensive urban redevelopment to support the rapid expansion of Tokyo.

The site has been completely and permanently redeveloped. There are no visible remnants of the original airfield, such as runways or hangars. The former grounds are now occupied by a large public park and major sports facilities. Key landmarks on the site today include the Tatsumi-no-Mori Seaside Park (辰巳の森海浜公園), the Tatsumi International Swimming Center (a venue for the Tokyo 2020 Olympics), and other recreational and sports facilities. The area is a fully integrated part of the Koto Ward's urban landscape.

The airfield, known as Susaki Airfield (洲崎飛行場) or Fukagawa Airfield (深川飛行場), was a significant pre-war and wartime aviation facility. Initially established in the early 1930s as a civilian airport on reclaimed land in Tokyo Bay, it was one of the capital's earliest airfields. It was soon taken over by the Imperial Japanese Navy Air Service and became a key naval air station. During World War II, it served as a base for naval aircraft, handling pilot training, aircraft maintenance, and air defense patrols for the Tokyo metropolitan area. Its location in the capital made it a strategic military asset.

None. There are absolutely no plans or prospects for reopening the airfield. The site is now a densely developed and highly valuable urban area consisting of a major park, world-class sports venues, and surrounding infrastructure. Re-establishing an airport at this location is physically, economically, and politically impossible. Tokyo's modern aviation needs are served by Haneda Airport (HND) and Narita International Airport (NRT).
