As a Japanese entity headquartered in Yokohama-shi, Kanagawa, the company operates under an X6 corporate structure with no federal certifications on record. While geographically based outside the United States, it maintains a dedicated presence in the U.S. defense supply chain, serving as a specialized offshore provider for high-value, technically demanding vessel sustainment work.
