The station building, built in 2006, is a timber structure in traditional Japanese style with a skylight.

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.

[6][7] In 2006, Ōkawa town authorities, in response to requests by residents, opened the Bizan Community Hall (眉山ふるさと館, Bizan-furusato-kan) to replace the station building which had been demolished in 2001.
