Oiwake Airfield

The primary reason for closure was the expansion and redevelopment of the adjacent Suzuka International Racing Course, which is also owned by Honda. The land occupied by the airfield was required for the construction of new spectator grandstands (specifically the Q1 and Q2 stands), expanded parking lots, and other essential infrastructure to better accommodate the growing scale of international events, most notably the Formula 1 Japanese Grand Prix.

The site of the former airfield has been completely redeveloped and integrated into the Suzuka Circuit complex. The area that once housed the runway is now occupied by the circuit's P8 and P9 parking lots, access roads, and the large Q1 and Q2 spectator grandstands, which provide views of the final 'S' curves and the approach to the main straight.

Oiwake Airfield, also commonly known as Honda Airfield or Suzuka Airfield, was a private airstrip owned and operated by the Honda Motor Co., Ltd. It was constructed in the early 1960s, concurrent with the opening of the Suzuka Circuit in 1962. Its main purpose was to serve Honda's corporate and motorsport activities. The airfield, which featured a single paved runway approximately 850 meters (2,788 feet) long, was used to fly in Honda executives, engineers, VIP guests, and racing drivers directly to the circuit. It also played a role in Honda's early aviation research and development activities. The ICAO code 'JP-2112' is an unofficial identifier used within the flight simulator community; the airfield did not have an official ICAO code as it was a private, unregistered strip.

There are no plans or prospects for reopening Oiwake Airfield. The land has been permanently repurposed and is now a critical and integral part of the Suzuka Circuit's infrastructure. Re-establishing an airfield on the site is considered infeasible due to the existing structures and the operational needs of the racing circuit.
