The Mitsubishi Steel Manufacturing Group has evolved over the years as an integrated manufacturer spanning everything from materials to finished products.

Our history began in 1904, when Tokyo Spring Works, our predecessor, launched the production of small springs for textile machinery. At the time, spring materials were largely imported from Europe and the United States. However, with the outbreak of the First World War, procurement of those materials became increasingly difficult. To sustain production, Tokyo Spring Works began manufacturing special steel itself as the material for springs. This is the origin of the Mitsubishi Steel Manufacturing Group’s manufacturing approach of connecting materials to products.

For more than 120 years, we have continued to refine the expertise and technologies that span the full spectrum from materials to products, thereby supporting the foundations of society and industry. Throughout our history, we have repeatedly encountered major shifts in our operating environment, including the impact of war, changes in demand following the end of the war, economic fluctuations, and the advance of globalization. Yet we have continued to take on challenges time and again. I believe this has been possible because the belief embodied in the Mitsubishi Steel Manufacturing Group’s Purpose : “Turning our passion into reality, We take on challenges to support a sustainable future.” has been passed down from generation to generation. We will continue to contribute to our customers and society through our unique manufacturing approach, connecting materials to products in pursuit of a sustainable society.

We are currently moving forward with various measures under the 2026 Mid-term Business Plan, which covers the three fiscal years from fiscal 2026 through fiscal 2028 , as we work toward realizing our vision for 2030.

At a time of growing global uncertainty, the business environment surrounding us is also reaching a major turning point. Under this Mid-term Business Plan, we will advance the restructuring of our core businesses to rebuild our earnings base and generate cash. At the same time, we will allocate management resources on a priority basis to strategic businesses that will serve as future drivers of profit growth, shifting them from the growth-building phase to the monetization phase.

Furthermore, these initiatives cannot be advanced without the capabilities of our human resources / our people. By developing talent and putting in place systems that support their growth, we will enhance our ability to execute as an organization and further reinforce our path to sustainable growth.

By pursuing these measures as one united group with the aim of enhancing corporate value, we will strive to meet the expectations of all our stakeholders.

We sincerely ask for your continued guidance and support.
