洋上風力を日本の新たな牽引産業にするための条件

――秋田県のケーススタディを中心に――

抄録

The Japanese government expressed the 2050 carbon-neutral declaration toward the world on October 2020. Then, in November of that year, the Offshore Wind Industry Vision set a national goal for electric power generation to be made 10 GW by 2030, and from 30 GW to 40 GW by 2040. And this package of policy decisions is enhancing the expectation feeling of offshore wind power business opportunities in Japan today.

However, Japanese huge windmill makers have withdrawn from that business, and supply chains for the huge windmill manufacturers are undeveloped in Japan. For that reason, the construction and manufacture of huge windmills of offshore wind power systems almost are depending on overseas makers.

Based on the above situations, this article aims to investigate the condition for Japanese offshore wind power to be the leading industry. Accordingly, we try to consider based on the following viewpoint.

First, an examination of the late cause of Japanese start-ups in this field and the withdrawal factor of Japanee huge windmill makers. Second, the explanation of the type of offshore wind power and its potential electric power generation in Japan, and the feature of the required supply chain networks. Third, the case study in Akita prefecture. Fourth, the analysis of success factors in Bremerhaven and Kingston upon Hull. And finally, the proposition of the condition for Japanese offshore wind power to be the leading industry in the light of industrial structurization and cluster formation.
