Company Profile| OS Electronics

Corporate Profile



When it was established in 1963, we were engaged in the manufacturing and sales of transistors under the name of OS Seiki Co., Ltd.

Since then, we have provided superior products and technologies to many customers in the field of electronics for more than half a century as a technology trading company.

What has been handed down since the company's founding is a thorough customer-focused attitude.

To be close to the customers who are responsible for manufacturing, and to provide creative support for solving the problems. Always pay attention to "Words make moves", clarify what needs to be done, explain it to customers, and translate it into action.

We believe that the trust and achievements of OS Electronics up to the present day can be attributed to the fact that we have not ended up as a businesslike, but have deeply thought about the bonds between people, and have achieved results with our customer-first stance.

Although the times have changed, the foundation of the relationship of trust remains unchanged.

As an electronics trading company, it is a matter of course that we gather and share technological information of the new age. We intend to continue to strive to be a "unique electronics technology trading company."

Thank you,

Takanobu Shoji
Chief Executive Officer
