Yamakoshi

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

Yamakoshi Station opened on 3 November 1903 as Yamakoshinai Station, a general station of the private Hokkaido Railway, when its Mori–Nepu section was completed. It was renamed Yamakoshi on 15 October 1904 to match the local district name. The line was nationalised in July 1907 and absorbed into the Hakodate Main Line on 12 October 1909. The Noda-oi–Yamakoshi section was double-tracked on 29 August 1969 and the Yamakoshi–Yakumo section on 26 September 1969. The building was rebuilt on 8 September 1920 and again on 6 October 1989. Freight handling ended in 1960, parcels in 1984, and the station was unstaffed from 1 November 1986. JR Hokkaido inherited it at the 1987 privatisation.

Beside the platform stands a waiting room shaped like an Edo-period barrier (sekisho), built to honour the nearby ruins of a Tokugawa-era checkpoint and known locally as 'Japan's northernmost sekisho'.
