Wakkanai Kouwanshisetsu Co., Ltd. is a company that mainly operates shipbuilding and repair businesses in Wakkanai City, the northernmost part of Japan.

We have set up three upper cranes for shipbuilding and repair of vessels less than 500 tons, and have installed 4,000-ton dry docks and floating docks that have a capacity of about 20 ships and can handle large ferries, meeting the expectations of our customers. By the way, as a port closest to Sakhalin, in recent years, we have been repairing and renovating large work boats engaged in the development of Sakhalin oil and gas resources, and have a reputation for high-level technology. In addition, in the onshore division, in addition to large tanks and pressure vessels, chemical machinery, power plants, large steel construction, etc., we also carry out inspection equipment for heavy vehicles, and their achievements are being evaluated.
