Message from the president

Following the words of Robert Jones, “You only fear the inner voice of your conscience, follow that!” we too have continued to challenge ourselves.
All of our employees challenge themselves for the company, and if we work hard every day, we can create a strong technical group. I believe that we can become a company that can contribute to society and become a respected business partner. While we are a young company, I would like to refine our techniques and skills to meet our customers’ expectations and continue to push forward toward our dreams.
