[3] The station, which is unstaffed, consists of a side platform serving a single track at grade in an area of rural farmland.

There is no station building, only a simple shelter made from disused rails on the platform.

[2][3] The private Miyazaki Light Railway (宮崎軽便鉄道) (later renamed the Miyazaki Railway) opened the station on 20 March 1915 as an additional station on a line which it had laid in 1913 between Minami-Miyazaki and Uchiumi (now closed).

Subsequently, Japanese National Railways (JNR) extended its then Shibushi Line north from Kitagō towards Minami-Miyazaki on the same route and reopened Sosanji as an intermediate station on 8 May 1963.
