Company Overview

Management Philosophy

Contributing to Society & Exploring New Fields Via New Water Hydraulic Technology

I first learned about water hydraulics while working with an oil hydraulic manufacturer. I was sure that it was the next generation’s driving technology and I established a new business as a manufacturer specializing in water hydraulics.
I will do my best to spread the use of water hydraulics and contribute to the global environment.
