History
The private Miyazaki Light Railway opened the station on 31 October 1913 as the northern terminus of a line to Uchiumi on the east coast of Kyushu. On 20 March 1915 the Miyazaki Prefectural Railway also opened a line from southwards to with this station as an intermediate stop. On 25 October 1916, the track at Kiyotake was linked up with the Japanese Government Railways Miyazaki Line which had been extended northwards from. The Miyazaki Prefectural Railway was nationalized and JGR designated the track to Miyazaki as part of the Miyazaki Line and later, on 21 September 1917, the Miyazaki Main Line. By 1923, the Miyazaki Main Line track had reached north to link up with the track of the Nippō Main Line at. On 15 December 1923, the entire stretch of track from Shigeoka through Miyazaki to Yoshimatsu, including Minami-Miyazaki, was designated as part of the Nippō Main Line. The Miyazaki Railway line between Minami-Miyazaki and Uchiumi closed on 1 July 1962. Using the route, Japanese National Railways extended its then Shibushi Line north from. A link up with Minami-Miyazaki was achieved on 8 May 1963 and JNR redesignated the entire stretch from Minami-Miyazaki to Shibushi as the Nichinan Line. With the privatization of Japanese National Railways, the successor of JGR, on 1 April 1987, Minami-Miyazaki came under the control of JR Kyushu. Throughout its history, the station has changed names several times. It was named Akae at its opening on 31 October 1913. On 1 July 1915, it was renamed Ōyodo. On 1 April 1942, its name was changed again to Minami-Miyazaki.
