Nippi Airfield

Economic and land-use conversion. The airfield was located on private land owned by the Nippi Corporation. The company expanded its Yamagata Plant's industrial operations, repurposing the land occupied by the runway for factory-related activities, including access roads and material storage.

The site has been fully absorbed into the Nippi Corporation's Yamagata Plant. Satellite imagery confirms that the former runway area is now an paved internal access road and open-air storage yard for the industrial facility. All aviation-specific infrastructure has been removed, and the land is completely dedicated to industrial use.

Nippi Airfield, known locally as Nippi Yamagata Gliderport (ニッピ山形滑空場), was a private airfield that served as a regional hub for recreational sport aviation. It was not a commercial or military airport. Its primary function was to support glider operations, and it was the home base for the Yamagata University Glider Club (山形大学航空部) and other local enthusiasts. The airfield featured an unpaved grass or dirt runway approximately 800 meters in length.

There are no known plans or prospects for reopening Nippi Airfield. The land has been permanently and completely redeveloped by its owner for industrial purposes, making a return to aviation use infeasible.
