A Word from the President

President Kazuyuki Tominaga

We have been involved in the manufacture of road safety products for many years as a manufacturer. And we think a big transition is currently coming not only nationally, but also globally regarding culture, economy, natural environment, and so on. However, we have to continue to grow and evolve without being overwhelmed by our environment. We integrated our main plant with our second plant on June 2013, and expanded our business globally by establishing the Vietnam plant as an Asian base. We will continue to streamline our company through facility investments, cost reductions, and technical development, and strengthen our competitiveness through product differentiation. In April 2014, which was the 50th anniversary of the foundation of our company, we established the Renewable Energy Division based on our consideration of the future energy situation, and started the manufacture and sale of photovoltaic module (solar panel) systems. We will work together as one for further development without fear of changes, friction, failure, and difficulties as stated in our corporate philosophy.
