[edit] History

The line was originally built as a link line between Mainland Japan and the then Japanese northern frontier Karafuto (southern half of Sakhalin Island). From Wakkanai Port, ferry to then Ōdomari (present Korsakov) served until the end of World War II.

The first segment of the line from Asahigawa (present Asahikawa) to Nagayama was built by the Hokkaidō Government Railway (北海道官設鉄道 Hokkaidō Kansetsu Tetsudō?) in 1898. The line eventually extended to Nayoro in 1903, and a railway to Wakkanai was completed in 1922 in the route of the later Tempoku Line (天北線 Tenpoku-sen?) via Hamatombetsu. The present route via Horonobe was first made as the Teshio Line (天塩線 Teshio-sen?).

After Japan's defeat of the war, the line lost the function as a link to Sakhalin, but remained important as a trunk line into the northern part of Hokkaidō. The heavily declining population of the surrounding area in recent decades, however, have made networked railway lines disappear one by one. The Sōya "Main" Line lost all branch lines, presently it is a long branch from Hakodate Main Line.
