Toyonuma

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

Toyonuma Station began on 20 March 1922 as the Railway Ministry's Toyonuma signal post (shingosho), established between Naie and Sunagawa, and was reclassified on 1 April of the same year as Toyonuma Signal Station (shingojo), the first of that name. The first signal station was abolished when the Naie–Sunagawa section was double-tracked in December 1926, but a second signal station was opened at the present location on 10 February 1942 when a 2.1 km dedicated line for Toyo Koatsu Kogyo was built, and it began handling freight to and from that dedicated line. It was upgraded from a signal station to a general station and began passenger service on 20 February 1947, becoming a hub for coal shipments to Toyo Koatsu Kogyo and, after the war, to Hokkaido Electric Power's Sunagawa Thermal Power Station. The station became unstaffed in November 1986; at the 1 April 1987 privatization and division of Japanese National Railways it became a station of both JR Hokkaido and JR Freight, and the JR Freight station was abolished in April 1990. The "Kitaca" IC card became usable there on 16 March 2024.

In response to flood damage from torrential rains in 1961 and 1962, the station building rebuilt in August 1964 was raised on a high floor with a waiting room, and — uniquely between Iwamizawa and Takikawa — was built facing away from the national highway.
