The Chōsen Anthracite Company, Ltd. was a kabushiki kaisha in colonial Korea that operated collieries around Korea. It was founded in 1927 by the Mitsubishi zaibatsu of Japan by integrating the anthracite mining operations around Heijō, eventually becoming the largest coal-producing company in Korea - 74.9% of the coal distributed in Korea was produced by the Chōsen Anthracite Company.
