Along with limestone, serpentinite has been found in vast quantities in Kochi Prefecture and was used as a crucial sub-material in the blast furnace steel-making process. Since the latter half of 1955, our company has mined over 36 million tons of high-quality serpentinite and supplied to major blast furnace steel manufacturers for over 50 years.
The skills we have developed in mining, selection, transport and quality control this time has accelerated our entry into the global market, allowing for supplying of an expansive selection of minerals from mines within Japan and abroad.
With a century’s worth of mining expertise, we strive to become the world’s leading supplyer of magnesium-based additives for steel production.

Since August 2012, we have begun a full-scale advancement into the overseas market with our investment in dolomite production for steel manufacturing at Anhui Hong Ri Mining Co., Ltd in Chizhou City of Anhui Province, China. Sending in our technical experts to the field, our focus has been in teaching quality control and production management at the factory with 400,000 to 500,000 tons produced annually. We plan to supply not only to Japanese steel manufacturers but also to China and Southeast Asia.
