Message from the President

Drastic advancements in electronics technology of the 21st century such as computers, cellphones, and digital cameras have brought us significant convenience.
However, living a life that relies heavily on electricity confronts us with climate change in return for the convenience. It would not be an exaggeration to say that generating and storing electricity without losing the convenience and relying on fossil fuels are the common issue for all humanity.
Our technology that realized high-capacity and high-power PAS capacitor before the times has potentialities to make the next leap forward in the field of reliable storage and supply of electricity.
I strongly believe that each step forward in the energy device field of our company is a step to create the future, overcoming a variety of challenges.
Mitsuo Nakajima
President and Representative Director
