Transform our business model from "Processing Special Steel" into "Creating Added Value from Materials" over the next 10 years.

The Mitsubishi Steel Manufacturing Group has evolved over the years as an integrated materials/product manufacturer with core competencies in the production and processing of special steels.
Our history began in 1904, when Tokyo Spring Works, our predecessor, launched the production of small springs for spinning machines. Spring materials in those days were largely imported from Europe and the United States, with token volumes produced domestically. The materials became difficult to procure from the start of the First World War, so, to continue producing springs, Tokyo Spring Works began producing special steel on its own.
Our company thus acted as a true "startup," long before the term was introduced, to produce the materials needed to make springs. Ever since, it's been part our corporate DNA to manufacture everything we need in-house, ranging from materials to finished goods, and to meet the associated challenges as they arise.

The 2016 Mid-term Business Plan we established as our compass for the five years from 2016 is based on the following slogan: Transform our business model from "Processing Special Steel" into "Creating Added Value from Materials" over the next 10 years.
We plan to respond to worldwide change by focusing on the development of new technologies and the creation of new value-added for materials. We're also committed to achieving synergies and additional growth by integrating our business operations and promoting globally competitive manufacturing processes.
To maintain our status as a business group trusted by stakeholders, we will continue making diverse social contributions through environmentally friendly business activities that place a strong emphasis on compliance management.
In all these efforts, we look forward to your continued guidance and support.
