[3] The station, which is unstaffed, consists of a side platform serving a single track at grade.

The platform is located on the opposite side of the track from the access road and is reached by means of a level crossing.

In a later phase of expansion, the track was extended west from Yamamoto to Imari, which opened as the western terminus on 1 March 1935.

With the privatization of Japanese National Railways (JNR), the successor of JGR, on 1 April 1987, control of the station passed to JR Kyushu.
