We are committed to building strong relationships with our suppliers, developing users at home and abroad, taking pleasure in developing together, refining our spirit of service, and being a company and people who can contribute to society.
From now on, we would like to actively address environmental issues and aim to procure materials that can contribute to Japan’s top technology.
We have overseas offices in Germany (Munich) and Korea (Seoul), and our head office is staffed with Chinese staff who should be able to handle Chinese business to build our business. The Company aims to strengthen its overseas business development, including imports and exports. Our strength is our ability to develop all kinds of electronic materials business through our network, both domestically and internationally.
We will especially specialize in power devices and 5G, the next generation semiconductors. This year, as we enter our 30th anniversary, we are looking back at our original intentions and want to do what we can to help even a single company, with an awareness of carbon neutrality. As a first step, we have introduced the fuel cell hydrogen vehicle ” MIRAI”as a company vehicle.　In addition, we will continue to work on BCP measures in preparation for disasters. We appreciate your continued guidance and encouragement.
