Yamanashi Airfield

The airport was closed due to land acquisition for a major national infrastructure project. The planned route for the JR Central's Chūō Shinkansen (a high-speed Maglev train line) passed directly through the airfield's property, necessitating its permanent closure and demolition to make way for the new railway.

The site of the former airfield has been completely transformed and is unrecognizable as an airport. The runway, taxiways, and hangars have been entirely demolished. The land is now occupied by the massive, elevated concrete guideway for the Chūō Shinkansen Maglev line, which is under construction. The former airfield is now an active, large-scale construction site for this high-speed rail project.

Opened in 1970, the airfield was officially known as Futaba Airfield (双葉飛行場, Futaba Hikōjō). It was a private airfield owned and operated by the prestigious Japan Aviation Academy (日本航空学園, Nihon Kōkū Gakuen), which has a campus nearby. For over 40 years, its primary and almost exclusive function was to serve as the flight training facility for the academy's students. Operations consisted entirely of general aviation, primarily light single-engine aircraft such as Cessna 172s, used for ab-initio and advanced pilot training. It was a crucial piece of infrastructure for one of Japan's most prominent aviation schools, training thousands of pilots during its operational life.

There are zero plans or prospects for reopening. The land has been permanently and irreversibly repurposed for the Chūō Shinkansen. The physical construction of the Maglev guideway on the former runway makes any return to aviation use impossible. The Japan Aviation Academy has relocated its primary flight training operations to other airports, notably Noto Airport (RJNW) in Ishikawa Prefecture.
