Since our founding in 1951, Tamaya Metal has upheld “integrity” as our guiding principle, delivering “safety and peace of mind” to society through our heat treatment technologies. The components we handle are widely used—from automobiles and precision machinery to aerospace and defense—and their quality is directly linked to people’s lives and safety. That is why we have never allowed compromise, continually striving for the highest standards of quality.

Heat treatment is a specialized process whose results are not easily visible from the outside; the sincerity of the process itself determines the outcome. The founder’s words, “Iron is honest,” reflect this very philosophy. Pouring our heart and expertise into the unseen aspects of our work has been the unchanging foundation of Tamaya Metal, and the reason we have earned our customers’ trust to this day.

Looking ahead, we aim to remain a “trusted presence” that stands firm even as times change. We strive to contribute to our customers’ growth, be a company our employees and their families can be proud of, and give back to our local community. We believe that this continual accumulation of trust will be the driving force that carries Tamaya Metal into the next 100 years.

Connecting the trust we have built over the years to the future, we will continue moving forward.
