COMPANY TAMAYAKIN
Human Resource Development for Manufacturing,
Company Development for Human Resource Development
Iron is honest
Kei Yamada, the founder and the first president of the company, left behind the words, "Iron is honest," referring to the nature of heat treatment processing, where the workmanship is not apparent from the outside, but the physical characteristics clearly reflect the previous history of heat processing.
In other words, the properties of steel at night in heat treatment reflect the sincere heart of the person working on it, and how to nurture such sincere people has its origin in "company development". We, at Tama Yakin, will continue to strive to pursue good "manufacturing", good "human resource development" to engage in it, and good "company development" as the basis of it.

We, at Tama Yakin, will continue to strive to pursue good "manufacturing", good "human resource development" to engage in it, and good "company development" as the basis of it.
SDGs
Heat treatment furnaces use heaters to heat up to around 1000℃, which consumes a lot of electricity. Therefore, heat treatment is considered to be one of the most electricity consuming processes in metal processing.
We installed solar panels on the roof of our factory in 2020 and are also using self-generated electricity for heat treatment.
We will continue to try to procure clean electricity with low CO2 emissions as one step toward a sustainable society while taking into consideration the global environment.

The form of this logo is a three-dimensional block that tightly combines the initial "T" for "Tama region," the birthplace of our company, and the initial "Y" for "metallurgy," the origin of our business when we started. The blocks are colored in these three colors to form the TAMAYAKIN brand logo, which expresses our hopes for the future.
