Sekihoku Main Line (石北本線 Sekihoku-honsen) is a Japanese railway line in Hokkaidō, operated by Hokkaido Railway Company (JR Hokkaido}} between Shin-Asahikawa in Asahikawa and Abashiri Station in Abashiri. The name comes from Ishikari Province (石狩国) and Kitami Province (北見国), names of ancient provinces along the line.[1]

Historically, the route between Sapporo and Okhotsk Subprefecture has changed for many times. Originally, the route took Hakodate Main Line to Asahikawa, then took southbound Nemuro Main Line and branched off from Ikeda, through Abashiri Main Line (網走本線 Abashiri Honsen) to Kitami. The route shortened a little when Nemuro Main Line opened the shortcut segment between Takikawa and Furano in 1913.
Another route, northbound from Nayoro to Kitami was completed as Nayoro Main Line (名寄本線 Nayoro Honsen) and Yūbetsu Line (湧別線 Yūbetsu-sen) in 1921.
The third route was a shortcut between Asahikawa and Engaru, straight through the Kitami Pass. Sekihoku Line (石北線 Sekihoku-sen), completed in 1932, finally opened the link route still used today.
The current Sekihoku Main Line is consisted of what these three lines have left. The section between Shin-Asahikawa and Engaru is from Sekihoku Line, the one between Engaru and Kitami from Yūbetsu Line, and the one between Kitami and Abashiri from Abashiri Main Line.
The Okhotsk limited express train, named after the Sea of Okhotsk, runs from Sapporo to Abashiri four times a day in summer, six times a day in winter.[2] The limited rapid train Kitami operates between Asahikawa and Kitami, with one return service daily.
As for the local service, the line is roughly divided into three segments. In the segment between Asahikawa and Kamikawa, the line functions as a commuter rail of Asahikawa City. There is one local train service per one to two hours. The segment between Kamikawa and Engaru is a sparsely populated area. Between Kakikawa and Shirataki, a local train runs one lap per day. For the segment between Engaru and Abashiri, there is one local train service per one to two hours.
