Message from President

We will contribute to society toward the creation of a dream-inspired future

Our company was founded in 1932 when Japan marked the beginning of its diamond tool industry. Since then, we have supported many manufacturing sites by leveraging the physical properties of diamond to our technologies and produced useful merchandise that help people to live a good life.

The products and service that we have delivered to the world, including semiconductors, electronic devices, information communication devices, automobiles, healthcare, and construction, are consistently being used at the forefront of production activities in variable industries of cutting-edge fields, winning high confidence from valuable customers.

The social environment has changed dramatically in the last half century with ongoing global warming, globalization of industrial structure, and advancement in the knowledge economy. Rapid sophistication of artificial intelligence began in the field of information communication technology, which is now beginning to spread deeply into our daily lives. Similar technological innovation will widely develop across every scene and environment in the coming years.

With the years of experience we have acquired working for various industries in dramatically changing societies and cultures, we have defined “continuing refinement of original discoveries and ideas to create new opportunities with a wide perspective” as our business policy . Taking this approach, we will commit and contribute to pioneering technological revolution in these turbulent times.

Yosuke Hamada
