Shipbuilding & Marine Equipment
Ehime Prefecture’s Imabari City boasts Japan’s largest concentration of shipbuilders with 14 manufacturing sites, including Imabari Shipbuilding Co., Ltd. — the number one shipbuilder in Japan and fourth largest in the world in terms of production volume.
Additionally, 160 companies locate near the shipbuilding yards, including marine manufacturers and related companies. From original ship-steering control technologies to marine equipment such as anchor handling winches, local offerings have received favorable assessments in Japan as well as internationally and have been employed in ships around the world. -
Large Plate Rolling & Machining
Ever since the opening of the Besshi Copper Mines in the late 17th century during the Edo period, the renowned Tōyo region has contributed to the development of domestic industries with companies, including Sumitomo Metal Mining Co., Ltd., Sumitomo Chemical Co., Ltd., and Sumitomo Heavy Industries, Ltd., as the site of a corporate “castle town” fostered by the Sumitomo Group. Among these, Sumitomo Heavy Industries in particular has taken on full-scale projects involving foundations for offshore wind power generation. Plant engineering projects have also developed in the area, featuring small and medium-sized enterprises with high technological capabilities involving non-ferrous metals, chemicals, and other fields, centered around the Sumitomo Group’s manufacturing business.

Operation & Maintenance
Ehime Prefecture aims to make market contributions with its superior technological capabilities in the O&M (Operations and Maintenance) sector as well. A number of technologies are expected to facilitate safe and stable operations and maintenance in offshore wind power generation projects. These include cutting-edge non-destructive inspection technologies employing wall-climbing robots for steel structures in conjunction with Phased Array Ultrasonic Testing (PAUT) probes as well as container crane elevator technologies boasting the largest domestic market share.
Ehime’s technology cluster — fostered over the years into a thriving state along the Seto Inland Sea, the site of one of the foremost industrial zones in Japan — is a driving force in offshore wind power generation in Japan and, indeed, the world.
The Unique Potential of Ehime
MESSAGE
Ehime Prefecture is home to a concentration of diverse, nationally preeminent manufacturing companies equipped with outstanding technological capabilities. These include a maritime cluster said to be the largest in Japan, comprising shipbuilding and marine equipment manufacturing companies, large plate rolling and machining operations that support heavy industry in Japan, and maintenance/inspection management for plants and other facilities — powerful drivers of the prefectural economy.
Also, further market expansion is expected in the offshore wind power generation sector in the future, due to factors including the growing momentum to realize carbon neutrality around the world. I consider this a promising market in which local Ehime companies will be able to leverage their impressive technological capabilities. The prefectural government has joined forces with local companies, advancing a variety of initiatives to achieve full-scale entry into the market, including establishment of the Ehime Prefecture Offshore Wind Power Industry Promotion Consortium in May 2024.
Amid these circumstances, we have put together an edition of our Database of “SUGOWAZA” Manufacturing Companies in EHIME, JAPAN specialized for the offshore wind power industry, which is characterized by a broad-based supply chain. Leading-edge technologies and sophisticated techniques from 32 local Ehime companies equipped to demonstrate their capabilities in their respective technology sectors, such as wind turbines, base manufacturing, and O&M.
Our hope is that this database will be of use in matching advanced technologies developed by local companies with offshore wind power industry projects by making them more widely known both within the prefecture and farther afield. If any of the companies listed in the database spark your interest, please do not hesitate to get in touch with the Ehime Prefectural Government’s Industrial Policy Division. I sincerely hope you will make a point of referencing this database, so that it might encourage the growth and further development of Japan’s offshore wind power industry and help create business opportunities for Ehime-based companies.
