About the Company

Based in the merchant town of Sakai, we would like to develop together with our beloved town “Sakai” with the ideal of a trading company that values the country of Japan and develops worldwide.
We hope to promote trade with the world based in the birthplace of Mikunigaoka.
We would like to be a company and people who can connect relationships with suppliers with a thick pipe, develop users in Japan and overseas, develop together, polish the spirit of service, and contribute to society.
From now on, I would like to actively work on environmental issues and aim to procure materials that can contribute to japan’s top technologies.
We have overseas bases in Germany (Munich) and Korea (Seoul), and we are building a business with Chinese staff who should respond to Chinese business at our head office.
We aim to strengthen our overseas business development, including imports and exports.
Our strength is that we can develop the business of all kinds of electronic materials through our network both in Japan and overseas.
In particular, we will specialize in power devices and 5G for next-generation semiconductors.
This year, we entered the 30th anniversary of the company, looking back on our initial intentions, being conscious of carbon neutrality, we would like to cooperate with one company. As a first step, we introduced “Mirai” fuel cell hydrogen vehicle as a company car.　In addition, we will work on BCP measures in preparation for disasters.
We look forward to your continued guidance and encouragement in the future.
