Odate–Noshiro Airport (大館能代空港, Odate-Noshiro Kūkō) (IATA: ONJ, ICAO: RJSR) is an airport in Kitaakita, Akita Prefecture, Japan and is 15.4 km (9.6 mi) west of Ōdate, at 84 m (276 ft) above sea level.

The airport is located in northern Akita Prefecture, primarily serving the city of Noshiro and the surrounding region, which includes tourist destinations such as Shirakami-Sanchi, Lake Towada, and Towada-Hachimantai National Park.

The airport terminal building makes extensive use of the local Akita cedar wood.

However, the low local population density and competition from the Akita Shinkansen and its proximity to the international Aomori Airport have limited profitable airline operations.

[4] The unsecured part of the terminal building also functions as a roadside station, a government-designated rest area along Akita Prefecture Route 324.
