History
Ōnogō began life as a signal box opened on 20 June 1942 along the existing Dosan Line track. The facility was closed on 1 September 1945 but reopened on 10 July 1946, and on 1 June 1947 it was upgraded to a full passenger station under Japanese National Railways. Following the 1987 privatisation of JNR, control passed to JR Shikoku and JR Freight. A private siding to a Sumitomo Osaka Cement factory carried limestone from Tokano Station, but freight operations ended on 1 October 1992. The station became fully unstaffed in September 2010. Some limited-express Nanpū and Ashizuri services have stopped at the station since the 2013 timetable revision.
