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 Hokkaido Government Railway in 1898. The line eventually extended to Nayoro in 1903, and a railway to Wakkanai was completed in 1922 along 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 in the war, the line lost its function as a link to Sakhalin, but remained important as a trunk line into the northern part of Hokkaido. The Sōya Main Line gradually lost all of its branch lines, and presently constitutes a long branch from the Hakodate Main Line.
