Okuma Diamond Device Inc.

Social implementation of technologies brought together beyond organizational boundaries
into the next growth industry.

Through the decommissioning project for the Fukushima Daiichi Nuclear Power Plant, we will bring together technologies that transcend organizational boundaries and implement them in society.
In particular, communication satellites, radars, and post-5G mobile phone base stations have areas that can only be solved by diamond.
Diamond semiconductors will become essential.
