Its business scope covers construction and construction material sales as a general trading company, serving major and local general contractors, housing manufacturers, and building material retailers.

The company operates from its headquarters in Fukuoka City, with a first logistics center in Hakata-ku, a Kitakyushu branch, and a Minami-Kyushu sales office in Kirishima, Kagoshima Prefecture. It also has a group company, Eco Plaza Co., Ltd., which handles new construction, renovation, and housing-related product sales and installation. Positioning itself as a regional solution provider, the company emphasizes contributing to the urban infrastructure development of Fukuoka City and Fukuoka Prefecture as a gateway to East and Southeast Asia. It also highlights its role in responding to natural disasters, which are frequent in the Kyushu region, and in proposing advanced construction materials and methods to the local market.
