History

The line was built as a link line between central and eastern Hokkaido, by Hokkaido Government Railway (北海道官設鉄道 Hokkaidō Kansetsu Tetsudō). The first section originally included as part of the Nemuro Line become classified as the Furano Line in 1913.

The first section of the current Nemuro Line was opened between Kushiro - Shiranuka in 1901. The line was extended westward, reaching Furano in 1907. In 1913 the Furano - Takikawa section opened, shortening the route by 53.5 km.

In 1911, 1st class sleeping accommodation was included on the Hakodate to Kushiro train, and a dining car was added from 1916.

The first section of the line east of Kushiro opened in 1917, reaching Nemuro in 1921.

In 1966, two major deviations opened, the first, east of Kanayama, associated with the construction of the Kanayama Dam, and the second between Ochiai and Shintoku, including the 5,790 m Shinkarikachi tunnel allowing the line to bypass the 1907 Karikachi tunnel and associated 1 in 40 (2.5%) grades.

In 1971, a refrigerated container train was introduced between Kushiro and Tokyo.

In 1981, the Sekishō Line opened between Shin-Yubari and Shintoku, becoming the main route between central and southeastern Hokkaido and shortening the distance for stations east of Shintoku to Sapporo by 43.4 km.

In 1990, a new tunnel and associated alignment opened near Atsunai, and a deviation near Shimanoshita associated with the construction of the Takisato Dam was opened in 1991.
