The station is served by the Nagasaki Main Line and is located 39.6 km from the starting point of the line at Tosu. In addition the station is also the starting point of the Sasebo Line.^[3] Besides the local services on both lines, the following JR Kyushu limited express services also stop at the station:^[4]

• Kamome - from Hakata to Nagasaki
• Midori - from Hakata to Sasebo
• Huis ten Bosch - from Hakata to Huis ten Bosch

The station consists of a side and two island platforms serving five tracks at grade. There is a passing loop between platforms 1 and 2 and several more passing loops/sidings south of the station beyond platform 5. The station is a hashigami structure where the station facilities are located on a bridge which spans the platforms and which has entrances to the south and north of the tracks. Located on the bridge are a waiting room, a staffed ticket window and the ticket gates. Elevators give access to the bridge from both the south and north station entrances. After the ticket gates, elevators lead down to the various platforms.^[3][2][4]

The private Kyushu Railway had opened a track from Tosu to Saga on 20 August 1891. In the next phase of expansion, the track was extended westwards with Takeo (today Takeo-Onsen) 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 Haiki to Nagasaki. On 1 March 1913, the station was renamed Hizen-Yamaguchi. On 1 December 1934, the stretch of track from Hizen-Yamaguchi through Takeo, Haiki to Sasebo was designated the Sasebo Line and Hizen-Yamaguchi replaced Haiki as the starting point. A new track branching from Hizen-Yamaguchi through Hizen-Ōura 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.^[5][6] On 23 September 2022, the station was renamed Kōhoku.

In fiscal 2016, the station was used by an average of 1,212 passengers daily (boarding passengers only), and it ranked 140th among the busiest stations of JR Kyushu.^[7]
