History
The private Kitakyushu Railway had opened a line between and on 5 December 1923. By 1924, the line had been extended westwards to. The line was extended again with Higashi-Karatsu opening on the east bank of the Matsuura River as the new western terminus on 15 June 1925. On 20 June 1929, the track was extended south down the east bank of the Matsuura River towards. Trains at Higashi-Karatsu executed a switchback before proceeding either south to Yamamoto or east to Nijinomatsubara. When the Kitakyushu Railway was nationalized on 1 October 1937, Japanese Government Railways took over control of the station. The line which served the station was designated the Chikuhi Line. The location of Higashi-Karatsu was inconvenient as the city centre of Karatsu lay on the west bank of the Matsuura River. Passengers wanting to access station in the city centre had to travel a long dog-leg south via Yamamoto or make a road or foot journey across the river. In 1983, the station was moved, opening at a new location to the southeast on 22 March. A through-track was established across the Matsuura River via to. The stretch of track down the east bank to Yamamoto with the intermediate stations of Kagami and Kuri was closed. Along with this change of route, the track from through Higashi-Karatsu to Karatsu was electrified. With the privatization of Japanese National Railways, the successor of JGR, on 1 April 1987, control of the station passed to JR Kyushu.
