The initial section of the line opened as an isolated railway connecting coalmines near Ebishima to the port at Rumoi in 1910, and was extended to Mashike in 1921.

The Ebishima - Fukagawa section opened in 1931, in conjunction with the opening of the first section of the Sassho Line, providing connection to Asahikawa.

Former connecting lines[edit]

The Sassho line between Ishikari-Numata and Shin-Totsukawa closed in 1972.

In 1930, the Tome Megumu private railway opened a 17.6 km line branching off at Ebishima to provide a rail line for coalmines in the Showa area north of the junction. This line closed in 1971.

The Teshio private railway opened in 1941, branching off at Rumoi and connecting a coal mine situated 30 km north of the junction until it closed in 1967. A 25km logging line connected to this line at the mine, operating from 1945-58.

The initial southern section of the Hoboro line from Rumoi opened in 1927. The initial northern section from Horonobe on the Soya Main Line opened in 1935, and the sections were linked in 1958. The line closed in 1987. The Haboro Coal Co. opened a 17km line from Chikubetsu on that line in 1941, closing in 1970. A 51.2km line was proposed from Chikubetsu to Shumarinai on the (now closed) Shinmei (Fukagawa - Nayoro) line with construction commencing in 1959. A substantial steel truss bridge was constructed before work was abandoned in 1962.


In 1946, a train derailed near Shaguma due to an avalanche, killing 17 passengers.[citation needed]

Avalanches also caused derailments on the line in 2012 and 2013, fortunately with no deaths.[citation needed]
