Fujioka (Shizuwa) Airfield

The closure was primarily due to the expiration of the land lease agreement. The airfield was operated by Honda on leased land. When the lease came up for renewal, Honda decided not to extend it, leading to the airfield's decommissioning and return of the land to its owners. The decision was logistical and economic, not the result of an accident, military conversion, or regulatory action.

The site of the former airfield has been completely redeveloped and no longer exists as an aviation facility. It is now the Fujioka Inter-Kita Industrial Park (藤岡インター北工業団地). The area is occupied by various commercial and industrial facilities, including logistics centers, manufacturing plants, and most notably, a large-scale solar power generation plant (a "mega solar" farm) that covers a significant portion of what was once the runway and surrounding grounds. A section of the former runway has been repurposed into a public road within the industrial park, but all other aviation infrastructure has been removed.

Fujioka (Shizuwa) Airfield, also widely known as Honda Airport or Fujioka Jōgai Richakuriku-jō (Fujioka Off-Field Landing and Takeoff Site), was a private airfield located in Fujioka City, Gunma Prefecture (not Tochigi as sometimes misidentified due to proximity). Its primary operator and user was Honda Motor Co., Ltd., through its subsidiary, Honda Airways. The airfield was integral to Honda's operations, serving several key functions:

1. **Corporate Transport:** Used for executive and employee travel between Honda facilities.
2. **Research & Development:** Played a role in Honda's early aviation research before the establishment of the dedicated Honda Airport in Okegawa, Saitama.
3. **Flight Training:** Served as a base for flight training activities.
4. **General Aviation:** The airfield was also accessible to the local general aviation community for recreational flying.

It featured a single asphalt runway, approximately 500-600 meters in length, suitable for light aircraft.

There are zero plans or prospects for reopening the airfield. The site has been permanently and fully repurposed for industrial and energy-generation use. The construction of large, permanent buildings and the installation of the extensive solar farm on the former runway make any future return to aviation activities physically and economically infeasible.
