Shift from “Processing Special Steel” to “Creating Added Value from Materials”
The history of the Mitsubishi Steel Group began with Tokyo Spring Works, the first spring manufacturer in Japan, established in 1904. Since then, in the course of a history of over 100 years, we have advanced as a company “Processing Special Steel.” As we look toward the next 100 years, we will contribute to the progress of society by responding to changes in the world and growing into a company “Creating Added Value from Materials.”
