President's Message

Shinichiro Eno
Shinichiro Eno

Guided by the voice of our customers.
Our obsession with technology grows stronger & stronger.

Since our foundation, based on the spirit of independence, we have refused to get caught up in the latest fads. Instead, we have stubbornly pursued original technology and the implementation thereof. The needs of society are sometimes hard to find, so we have been listening directly to the voices of our customers, which lays the foundation for our R&D endeavors. Our R&D activity must continue to be focused on components with challenging technical aspects and high added value.

I believe one of the best ways to continue meeting customer expectations and needs is by having a clearly defined technical development path and having our feet planted firmly on the ground.

If living is to make continuous improvements, the fact that one can continue to improve oneself through work is a wonderful thing indeed. I believe our company becomes stronger when each individual employee has a personal sense of fulfillment derived from the contributions to society realized from our developed product. This ultimately leads to increased customer satisfaction.

We will continue to move forward one step at a time.
