The Karatsu Kogyo Railway had opened a track from Miyoken (now ) which, by 25 December 1899, had reached Azamibaru (now ). On 23 February 1902, the company, now renamed the Karatsu Railway, merged with the Kyushu Railway which undertook the next phase of expansion. The track was extended east, with opening as the final eastern terminus on 14 December 1903. Ogi opened on the same day as an intermediate station on the 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 line which served the station was designated the Karatsu 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.
