Message from the
Representative Director

We are committed to continuously applying the technical expertise and customer-focused know-how we have cultivated over the years to connect people responsibly and contribute to building a safe and secure society.
As we navigate changing times, we will continue to identify what should be passed on to the next generation and what needs to change, progressing step by step and prospering together.
To meet the demands of an information and communications society undergoing rapid transformation, we must quickly respond to change, engage in cross-sector discussions to find solutions, and collaborate to deliver results. Rather than relying solely on technology for societal growth and sustainability, our entire team will work to ensure that society grows and prospers together with our customers.

Our company embraces the principle of “valuing the three MYs”:
My Customer (Customers)
My Family (Employees and their families)
My Company (The Company)

In other words, if our customers are satisfied and our employees find their work fulfilling, the company will naturally be healthy, earn customers’ trust, and be a reliable support for employees and their families.
We will pursue sustainable growth and development.

Yoshitaka Mitsuhashi,
Representative Director
