The private Kyushu Railway had opened a track from to on 20 August 1891. In the next phase of expansion, the track was extended westwards with Takeo (today) opening as the new western terminus on 5 May 1895. Hizen-Yamaguchi (then known as Yamaguchi) was opened on the same day as an intermediate station along the new stretch of track. When the Kyushu Railway was nationalized on 1 July 1907, Japanese Government Railways (JGR) took over control of the station. On 12 October 1909, the station became part of the Nagasaki Main Line, which at that time, ran through Takeo and to . On 1 March 1913, the station was renamed Hizen-Yamaguchi. On 1 December 1934, the stretch of track from Hizen-Yamaguchi through Takeo, to was designated the Sasebo Line and Hizen-Yamaguchi replaced Haiki as the starting point. A new track branching from Hizen-Yamaguchi through to Nagasaki built from 1930 to 1934 was designated the Nagasaki Main 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. On 23 September 2022, the station was renamed Kōhoku.
