Nakajima Airstrip

Economic reasons and land redevelopment. The private owners of the land sold or leased the property for a more profitable venture. The site was subsequently developed into a large-scale solar power plant, a common fate for many small, private airfields in Japan due to land value and energy policies.

The site of the former airstrip has been completely redeveloped and is now occupied by the 'Takasaki Nakajima Mega Solar Power Plant'. The runway, hangars, and any other aviation-related infrastructure have been removed and replaced by extensive arrays of solar panels. The distinct linear shape of the former runway is still visible in satellite imagery, but it is now entirely covered by the solar farm.

Nakajima Airstrip was a private, post-war general aviation facility. It was officially classified as a 'jōgai richakuriku-jō' (場外離着陸場), which translates to an 'off-airfield landing and takeoff site', meaning it was not a fully regulated public airport. Its primary function was to serve the local recreational and private aviation community. Operations included flights by light aircraft, ultralights, and possibly gliders. The name 'Nakajima' derives from its geographical location in the Nakajima-machi district of Takasaki, Gunma Prefecture. While the Gunma region is historically famous as the home of the WWII-era Nakajima Aircraft Company, this specific airstrip was a modern, private facility and not a direct remnant of the historical company's operations.

There are no known plans or prospects for reopening the airstrip. The complete conversion of the land into a significant energy infrastructure project (the solar farm) makes a return to aviation use virtually impossible without the complete removal of the current facility, which is highly improbable.
