Company Overview

From our very first days we have handled the installation and inspection of all types of boilers, water supply construction, and the construction of air conditioning and sanitation facilities. From there we have grown, offering a wider range of construction services including the manufacture, installation and various piping work for petrol and chemical plant equipment. As a nationally certified welding factory, we have grown our business in the nuclear energy sector since 1971. In 1990, we consolidated our operations at our current location in Kurosuno and have been expanding our facilities since.

Future Prospects & Areas of Interest

In the nuclear field, we believe we can contribute to decommissioning efforts (wastewater treatment facilities, fuel rod removal, etc.). For hydrogen, we can provide hydrogen generation equipment units. And for environmental work, we believe we can make contributions to the
construction and maintenance of biomass power generation facilities.
