Hokkaido Colliery and Railway Company (北海道炭礦鉄道, Hokkaidō Tankō Tetsudō)[1] was a company engaged in coal mining, railway operation and shipping in Hokkaidō, Japan.
At this time the company was renamed Hokkaido Colliery & Steamship Co., Ltd. (北海道炭礦汽船, Hokkaidō Tankō Kisen), which continued mining until 1995 and is in business of coal importing from Russia as of 2014.
The section from Oiwake to Shin-Yubari (Momijiyama) is a part of the Sekishō Line (Main section) today while the remainder became the Yubari Branch Line which closed in 2019.
The company leased this section to Japanese Government Railways.
As the Railway Nationalization Act was promulgated, on October 1, 1906, the company's railway (207 miles 51 chains), rolling stock (1,940), steamship (1), personnel (3,673) and other goods and contracts were transferred to the government of Japan, in exchange of 30,997,100 yen worth of government bond.
