Company information
Since our founding in 1916 (Taisho 5), we have walked through turbulent times as "Kobe Foundry." During this period, while making iron castings the cornerstone of our business, we have diversified our operations in response to changing times, expanding into various fields such as labor-saving technologies, energy conservation, environmental improvement, and functional materials. Then, in December 1993, marking our 77th anniversary, we took a new step forward as "Nijigi." The name "Nijigi" encapsulates diverse technologies into a seven-colored concept, likened to a rainbow. Just as a rainbow brightly colors the sky and brings refreshing dreams and hopes, we aspire for our future vision to be that of a "company that always shines amidst rapid changes."
