Message from the President

Illuminating the Earth’s Resources
Manufacturing That Begins With Copper, but Goes Beyond
Sustainable Manufacturing Practices

Since our founding in 1898, Kiyomine Metal Industry has consistently worked with copper as a core material. From traditional tableware and musical instruments to modern automobiles and smartphones, our products have supported everyday life across generations.
Our journey has not always been easy. As the environment, society, and technology continue to evolve, we’ve faced the daily challenge of discerning what must change—and what must remain unchanged.

Today, our thinking goes beyond manufacturing. We ask ourselves: “Is it enough to simply produce, consume, and discard?”
We are reimagining manufacturing for the next generation. Copper is a metal that can be created, used, and endlessly renewed. We strive not only to produce, but to circulate resources and connect them to the future.
What we’ve learned from copper, we aim to apply to all of Earth’s resources—steadily and responsibly.

We are joined by passionate individuals who love manufacturing and want to be involved beyond the act of creation—who seek to redefine consumption itself.
The future of our company is still being shaped. And we cannot do it alone. It is something we build and circulate together with like-minded partners inside and outside our organization.

We look forward with excitement to what we can achieve together next.
