We operate our business across a wide range of value chains, from steel manufacturing and steel product sales to steel processing, parts manufacturing, maintenance, and recycling.

Building value chains through material supply, processing, and manufacturing

In steel manufacturing, we are working to expand our business base in Japan and overseas through investment in Yamato Kogyo Co., Ltd., the largest independent electric furnace manufacturer in Japan, and are building a steel product supply framework in emerging countries experiencing rapid growth. We have also established a solid sales network through Mitsui & Co. Steel, Ltd., Regency Steel Asia Pte Ltd, MM&KENZAI Corporation, and Nippon Steel Trading Corporation, which engage in the trading of steel products.

In the field of steel processing services, we own approximately 30 processing centers in North America, which we acquired through investment in Steel Technologies LLC of the U.S. In 2024, we established a new electrical steel sheet processing company, Polska-Mit Steel sp. z o.o., in Poland, further expanding our existing operations in the Netherlands, China, Czech Republic, and Canada. This will expand the supply chain for transformers and electric vehicles through processing, inventory management, and inspection services. In the area of parts manufacturing, downstream in the supply chain, we invested in Gestamp Automoción, S.L., an auto parts manufacturer with over 100 locations worldwide, as well as in GRI Renewable Industries, the world’s largest manufacturer of towers for wind power. Through these and other investments in the manufacturing industry, we are building value chains that extend beyond steel product trading and processing.

Building a sustainable and stable supply foundation through strategic business development

As the aging of infrastructure is increasingly becoming a global social issue, and amid growing interest in circularity, we have strengthened our maintenance business that contributes to extending the lifespan of structures and facilities through our investment in SHO-BOND & MIT Infrastructure Maintenance Corporation in 2019 and in Structural Technologies, LLC, an infrastructure repair company, in 2023.

In the energy sector, in addition to the acquisition of all shares of STATS (UK) Ltd. in 2023, which manufactures pipeline repair equipment and provides engineering services, we strengthened business development that contributes to a stable supply foundation through the acquisition of Global Energy Service Holding Ltd. in 2025, a UK-based company engaged in steel processing, equipment manufacturing, and base port operations for the energy industry.

To build a low-carbon / de-carbonized society, in addition to contributing to material supply, we are working with the Mineral & Metal Resources Business Unit to develop a closed-loop recycling model in collaboration with manufacturers and customers. Through these initiatives, we are working to solve the problems faced by every stakeholder in the supply chain.
