The private Kyushu Railway had, by 1909, through acquisition and its own expansion, established a track from Kokura to Yanagigaura down the east coast of Kyushu. The Kyushu Railway was nationalised on 1 July 1907. Japanese Government Railways (JGR), designated the track as the Hōshū Main Line on 12 October 1909 and expanded it southwards in phases over the next 13 years, establishing Shigeoka as its southern terminus on 26 March 1922. At the same time, JGR had been expanding its Miyazaki Main Line north from Miyazaki, reaching Ichitana, just 9 km south of Shigeoka by July 1923. The link up between the two lines was achieved on 15 December 1923, establishing through traffic from Kokura in the north to Miyakonojō. The entire stretch of track was then renamed the Nippō Main Line. On the same day,
Sōtarō was opened as a signal box on the linking track. On 1 March 1947, Sōtarō was upgraded to a full station. The station has been unattended since 1972. With the privatization of Japanese National Railways (JNR), the successor of JGR, on 1 April 1987, the station came under the control of JR Kyushu.[5][6]
