Greetings from our CEO & President

In the spirit of “everyday creating,”
To become an essential company for our customers.

We believe that our main businesses, “Photonics/Optics” and “Thermoelectrics,” will greatly contribute as fundamental technologies to support the sustainable society of the future. On the other hand, from the viewpoint of protecting social infrastructure and daily life from inevitable natural disasters, the need for lightning protection, UPS, and metal bonding technology will continue to increase.

While contributing to society with world-class technology, we will continue to be a highly engaged company that is connected with many customers with “emotions” such as “I’m glad to be with Hakusan” and “I wonder what would have happened if it hadn’t been there.” is our wish.

Hakusan Inc. aims for further growth as a company that creates the future through the rapidly growing optical business, research and development activities that create new businesses, and the environmental energy business and special equipment business that challenge new projects.
