Tachiarai East Airfield

Land redevelopment for economic purposes. The primary reason for the closure was the sale of the land for the construction of a large-scale solar power plant. This redevelopment made the site physically unusable for any aviation activities.

The site is permanently closed and no longer recognizable as an airfield. The southern portion of the former runway and surrounding area is now occupied by the 'Asakura Hiratsuka Solar Power Plant'. The remaining northern section of the former runway is overgrown with vegetation and appears to be fallow or used for agriculture. No airport infrastructure, such as hangars or markings, remains visible or intact.

The airfield was situated on the grounds of the former Tachiarai Army Airfield's East Runway, a historically significant Imperial Japanese Army Air Service base during World War II. The original Tachiarai complex was one of Japan's largest and most important air bases, serving as a major flight training school, an aircraft depot, and a departure point for Kamikaze special attack units. After the war, this specific site was repurposed and eventually operated as Tachiarai East Airfield (JP-2406), a private, unofficial airfield known in Japan as a 'Jōgai Rikōrikujō' (off-airfield landing site). In its final decades, it was primarily used by a local flying club for recreational flying, particularly for ultralight aircraft and motor gliders.

Zero. The construction of the permanent solar farm infrastructure on the land has made the site's reversion to an airfield impossible. There are no known plans or prospects for reopening.
