Message

Since our establishment in 1957, we have been involved in "manufacturing" in a wide range of social fields.

At the time of establishment, our main business was lignin sales, but we entered the automobile industries to respond to changes in the economy and society. And we have grown together with our customers while responding to various needs, mainly selling materials necessary for manufacturing iron castings.

In the coming era, the business environment will change at a tremendous speed and become more complex.

Even in such a situation, we value “He that would know what shall be, must consider what has been”, adapt to changes in the environment, work on businesses that benefit society, and aim to be a company that always walks with you all.
