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

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.

Japanese Government Railways (JGR) assumed control of the station and designated the track which served it as part of the Chikuhi Line.

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