MESSAGE
From the President
"The power to give shape to ideas."
Material Inc.
President Ryunosuke Hosogai
Manufacturing that connects to the future.
"Value the ties between people, and remain a company our customers need." That has been our conviction since founding. Starting as a material supplier, we have grown into an integrated operation, from precision machining on machining centers through to quality assurance.
Our role is not just to make and deliver. It is to worry over our customers' problems with them, think with them, and propose the best answer. "The power to give shape to ideas" means giving shape to our customers' wishes, to our employees' challenges, and to the future of manufacturing in our region. Change what must be changed; stubbornly protect the trust that must be kept.
