History
Ina-Ōshima Station opened on 13 July 1922 as the terminus of an Ina Electric Railway extension from Kami-katagiri. On 15 January 1923 the line was extended further to Yamabuki, leaving Ina-Ōshima as an intermediate stop. The line was nationalised on 1 August 1943 and absorbed into the Iida Line, passing to the Railway Ministry and then to Japanese National Railways. Freight handling ended on 1 December 1971 and parcel handling on 14 March 1985. The station became night-unstaffed on 1 November 1986, and on 1 April 1987 it passed to JR Central with the privatisation of JNR. A new station building was completed in February 1994, and the station shifted to municipal simplified-consignment operation on 1 April 2013.

Notes
The surrounding district is known locally as Motoōjima or Ōjima, both pronounced with a voiced sound, but the station name is rendered with the unvoiced reading "Ina-Ōshima."
