The station building is a wooden structure of western design and houses a waiting area and a staffed ticket window.

It staffs the ticket booth which is equipped with a POS machine but does not have a Midori no Madoguchi facility.

By 1928, the track had been extended eastward and had linked up with the Inukai Line (犬飼線) which had been built westward from Ōita.

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.
