On 19 November 2016, JR Hokkaido's president announced plans to rationalise the network by up to 1,237 km, or ~50% of the current network,[1] including proposed conversion of the Nayoro - Wakkanai section of the Soya Line to Third Sector operation, but if local governments are not agreeable, the section will face closure.
One Sōya limited express service operates each way between Sapporo and Wakkanai daily, and two Sarobetsu limited express services also operate each way between Asahikawa and Wakkanai daily.
All-stations "Local" train services operate between Asahikawa and Nayoro, at approximately 1 to 2 hour intervals. All-stations "Local" train services operate between Nayoro and Wakkanai, at approximately 3 to 4 hour intervals. Four Rapid Nayoro services operate between Nayoro and Asahikawa in each direction daily.

The line was originally built as part of a link between mainland Japan and the then Japanese northern frontier of Karafuto (southern half of Sakhalin Island). From Wakkanai Port, a ferry to then Ōdomari (present Korsakov) operated 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 was extended to Nayoro in 1903, and to Wakkanai in 1922 along the route of the later Tempoku Line (天北線, Tenpoku-sen) via Hamatombetsu. The present route via Horonobe was opened as part of 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.
