[3][2] The private Miyazaki Light Railway (宮崎軽便鉄道) (later renamed the Miyazaki Railway) opened the station on 31 October 1913 as an intermediate station on a line it had laid between Minami-Miyazaki and Uchiumi (now closed).

The station closed when the Miyazaki Railway ceased operations on 1 July 1962.

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

With the privatization of JNR on 1 April 1987, the station came under the control of JR Kyushu.
