• JR Nippo Line: Kitsuki ⇄ Hiji

Ōga Station opened on 1 June 1952 as a new intermediate stop on the existing Nippō Main Line, established by Japanese National Railways after local residents had petitioned for a station for roughly three decades. The single island platform sits 103.3 km from the line's starting point at Kokura, in Hiji, Ōita Prefecture. Following the privatisation of JNR on 1 April 1987 the station passed to JR Kyushu. Operations were outsourced to JR Kyushu's station-services subsidiary in later years, and on 1 April 2022 the post was changed from an outsourced station (gyōmu-itaku) to a simple-commission station (kan'i-itaku); a ticket window remains in place.

Trains arriving at the station automatically lower a level crossing that blocks pedestrian access between the station building and the island platform.
