What we support is safe and seamless maritime operation.

Toyo Sangyo Co., Ltd. is a professional maritime service company supporting a wide range of marine operations.

We primarily provide husbanding and attendance services, as well as the collection and transportation of waste oil, bilge water, and other ship-generated waste, when foreign naval vessels—including those of the U.S. Navy—cruise ships, and ocean-going vessels call at Japanese ports, mainly in Yokohama and Yokosuka.

In addition, we offer a range of support services for government vessels, including those operated by the Japan Maritime Self-Defense Force and the Japan Coast Guard.
