About Us

In recent years, we have been actively seeking new and advanced ingredients in the international market
Our lives in Japan have been affected by many changes, both global and domestic: declining population and birthrate, increased life expectancy, growing influx of foreigners, EV shift, social media, IoT, bit coin banking, sharing economy, and AI to name a few.

All members of society need to adjust to these changes. At the company level, these adjustments are a matter of survival, given the competitive tone of the times.

Our company, founded in 1952 as a distributor for Maruzen Oil (now Cosmo Oil Co., Ltd.), has been supplying raw materials for the road paving industry, the construction waterproofing industry, and the ink industry for more than 60 years.

Our company's motto is "The site is first." It reflects our policy of visiting customers regularly and making every effort to supply raw materials effectively and to solve any problems our customers may encounter.

In recent years, we have been actively seeking new and advanced ingredients in the international market in order to inform our customers of the state-of-the-art materials. Japan being an island country, we strive to find new raw material sources by building partnerships with foreign suppliers.

Living in this era of great changes is challenging, but it presents immense opportunities for growth and prosperity. We believe that by making our customers strong, our company will grow stronger as we work together to create a better world.
