The station serves Ōzai, a village that has now been merged into Ōita City and is typically busy with commuter traffic. It is also the nearest station to the Nippon Bunri University located at the nearby Ōita suburb of Sakanoichi.[1]

The station consists of a side platform and an island platform serving three tracks at grade. The station building is a modern concrete structure with a distinctive saw-tooth roof. It houses a waiting area, SUGOCA card readers and a staffed ticket window. Access to the island platform is by means of a footbridge. Bike sheds and parking are available at the station forecourt. Next to the station building is another footbridge which links the streets on both sides of the tracks.[2] [3] [4] Although it is an unmanned station, automatic ticket vending machines are installed.
Japanese Government Railways (JGR) opened the station on 25 November 1924 as an additional station on the existing track of its Nippō Main Line. With the privatization of Japanese National Railways (JNR), the successor of JGR, on 1 April 1987, the station came under the control of JR Kyushu.
