Coal used as general fuel. In the past, it was widely used in homes as fuel for boilers and stoves, and most of it was consumed for electricity and cement manufacturing, but as the energy revolution progressed, it was replaced by oil and gas. However, after the oil crisis, coal was reconsidered as a cheap and abundant fuel under the policy to move away from oil, and demand has been increasing. Domestic coal production is mainly steam coal, at about 7.87 million tons. Of the total import volume of about 104.84 million tons, about 40% is steam coal.

一般の燃料用に使われる石炭。かつてはボイラー,ストーブなどの燃料用として家庭などに広く用いられ,またその大部分が電力用,セメント製造用などとして消費されていたが,エネルギー革命の進むなかで石油,ガスなどに取って代られた。しかし,石油危機を契機に脱石油政策のもと安価で豊富な燃料として輸入炭を中心に見直されてきており,需要量も増加してきている。石炭の国内生産量は一般炭が主体で約 787万t。また,全輸入量約1億 484万tのうち4割程度が一般炭である。
