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

On 19 November 2016, JR Hokkaido's President announced plans to rationalise the network by up to 1,237 km (769 mi), or ~50% of the current network,^[2] including the proposed conversion to Third Sector operation of the Sekihoku Main Line, but if local governments are not agreeable, the line will face closure.

History[]

The principal route between Sapporo and Okhotsk Subprefecture has changed several times. Originally, the route was the Hakodate Main Line to Asahikawa, then the southbound Nemuro Main Line and then the northbound line from Ikeda, via the Abashiri Main Line (網走本線, Abashiri-honsen) to Kitami. The route shortened by 53.5 km (33.2 mi) when the section between Takikawa and Furano on the Nemuro Main Line opened in 1913.^{[citation needed]}

Another route, northbound from Asahikawa to Nayoro, then southeast to Kitami was completed as the Nayoro Main Line (名寄本線, Nayoro-honsen) and Yūbetsu Line (湧別��, Yūbetsu-sen) in 1921.^{[citation needed]}

A third route was a shortcut between Asahikawa and Engaru, straight through the Kitami Pass. The Sekihoku Line (石北線, Sekihoku-sen), completed in 1932, finally completed the main route still used today.^{[citation needed]}

The current Sekihoku Main Line consists of the remnants of these three lines. The section between Shin-Asahikawa and Engaru is from the Sekihoku Line, the section between Engaru and Kitami from the Yūbetsu Line, and the section between Kitami and Abashiri from the Abashiri Main Line.^{[citation needed]}

The first of the abovementioned sections to open was from Abashiri to Kitami in 1912. The Kitami to Engaru line was opened between 1912 and 1915 as a 762 mm (2 ft 6 in) gauge line, but was converted to 1,067 mm (3 ft 6 in) gauge in 1916.^{[citation needed]}

The Asahikawa to Kamikawa section opened between 1922 and 1923, and the Engaru to Shiritaki section between 1927 and 1929. The final section, including the Ishikita tunnel, opened in 1932.^{[citation needed]}

In July 2015, JR Hokkaido announced that it would be closing four stations line (Shimo-Shirataki Station, Kyu-Shirataki Station, Kami-Shirataki Station, and Kanehana Station) in March 2016, due to low passenger usage.^[3]
