Hashioka Station opened on 21 February 1897, when the Sanuki Railway's line between Takamatsu and Marugame opened. Operations were transferred to the Sanyō Railway on 1 December 1904, and the station was nationalized and became a station of the government railway on 1 December 1906. Delivery handling was discontinued on 1 October 1969, freight handling on 1 June 1970, and baggage handling on 14 March 1985, in that order. An overpass was installed and put into service on 3 September 1971, and the station became one of Shikoku Railway Company (JR Shikoku) at the division and privatization of Japanese National Railways on 1 April 1987, with station number Y03. A platform was added as part of station improvement work in 2002, and the ICOCA IC card became usable from 1 March 2014. On 16 March 2024 the station became unstaffed all day, and the charging machine was also taken out of service. It is the principal station of the former Kokubunji-chō and is served by the rapid service "Sunport."

Because platform 1 shares its station-building-side track with platform 0, the station has a nationally unusual configuration of five platforms for four tracks, which allows rapid and local trains to connect at the same platform.
