About Our Divisions
Squarely focused on the demands of the times,
we provide cutting-edge materials.
Today, modern society demands environmentally-conscious products (energy-saving products represented by electric vehicles, hybrid cars, etc. as well as products utilizing recycling technology). In addition to this, with Japan’s rapid transformation into an aging/welfare society, the development of products to address these issues (such as small sized commuter vehicles and robots for nursing and assistance) continues to progress.
As a manufacturer specializing in the delivery of cutting-edge materials, Santoku has consistently and continually created a wide range of products. With the high demand for cutting-edge materials ever-growing, we have taken it as our mission to deliver high performance, high added value materials and will continue to advance product development that is squarely focused on the needs of the times.
