Onakayama

Departure data for this station is not available on this site.

Ōnakayama Station opened on 1 December 1946, in response to residents' requests, as Ōnakayama provisional stopping place (bureau-designated) on the state railway's Hakodate Main Line, handling passengers only. It passed to Japanese National Railways in 1949, and was upgraded to a full passenger station on 15 January 1950, becoming Ōnakayama Station and beginning parcel handling. On 4 September 1962, with the double-tracking of the Kikyō–Nanae section, the present down-side platform was completed and a footbridge was installed. The station was unstaffed on 1 November 1984, and passed to JR Hokkaido at the division and privatization of Japanese National Railways on 1 April 1987. In 2013 the old station building was demolished and rebuilt, with the new building entering service on 12 December of that year; on 26 March 2016, in step with the opening of the Hokkaido Shinkansen, the Goryōkaku–Shin-Hakodate-Hokuto section was electrified; and on 16 March 2024 the Kitaca IC card became usable at the station.

The name Ōnakayama comes from two predecessor villages that merged here — Ōkawa, named after the Ōkawa river running through it, and Nakajima, named after Nakajima Tatsusaburō, the colonisation officer of the Hakodate magistrate's office in 1858 — whose names were combined for the new village.
