Hokkaido Colliery and Railway Company

Hokkaido Colliery and Railway Company (北海道炭礦鉄道) was a company engaged in coal mining, railway operation and shipping in Hokkaidō, Japan.

The company was established in 1889 when the state-owned Horonai Coal Mine (幌内炭鉱) and Horonai Railway were sold to the company. The company developed coal mines and transported coal to consumers by its own railways and a fleet of steamships.

The railway of the company was nationalized on October 1, 1906 under the Railway Nationalization Act. At this time the company was renamed Hokkaido Colliery & Steamship Co., Ltd. (北海道炭礦汽船), which continued mining until 1995 and is in business of coal importing from Russia as of 2014.
