Shimonuma

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

Shimonuma Station opened on 25 September 1926 as a general station, when Japanese Government Railways extended the Teshio Line between Horonobe and Kabutonuma. The Teshio Line was absorbed into the Sōya Main Line on 1 April 1930, and the station passed to Japanese National Railways in 1949. Freight handling ended in 1977, parcels in 1984, and the station was unstaffed from 10 November 1984. In July 1985 the old station building was replaced with a converted Yo 3500 brake-van structure. JR Hokkaido took over at the 1 April 1987 privatisation. Since April 2021 Horonobe Town has maintained the station, funded in part by furusato nōzei donations, citing its role as a gateway to the Sarobetsu wetlands.

The station building was repainted in 2017 under Horonobe's My Station campaign in an image evoking Numahikyon, the station's own character created by the town.
