Japan offshore wind project ambitions have reached a landmark milestone as Oga Katagami Akita Offshore Green Energy LLC (OKAOGE) signed a historic contract with Kajima Corporation on October 23 for the 315 MW Akita Offshore Wind Project. As part of the agreement, wind turbine foundations will be manufactured, purchased, transported, and installed, initiating full-scale construction for one of Japan’s biggest offshore wind projects. This offshore wind project in Japan is a significant step toward the nation’s carbon-neutral and clean energy goals.
Renewable Energy Meets Local Revitalization
The offshore wind project in Japan prioritizes coexistence with nearby fisheries and coastal communities in addition to producing clean energy. OKAOGE seeks to advance sustainable regional revitalization, creating jobs and stimulating economic growth across Akita Prefecture.
The company intends to create a self-sustaining agricultural and fisheries sector by utilizing ITOCHU Corporation’s commercial infrastructure and working with nearby companies, guaranteeing that the advantages of renewable energy effectively reach the local community.
Building Japan’s Offshore Wind Workforce
With 86% of its workforce hired from Akita, OKAOGE is poised to become the largest offshore operations and maintenance (O&M) company in Japan. In addition to providing a trained workforce to support future offshore expansions throughout Asia, this initiative will bolster Japan’s domestic offshore wind industry.
With Kajima Corporation on board, the Japan offshore wind project is entering a new era of growth, technological innovation, and industry leadership.
Shaping the Future with Akita Winds
Under the vision “Shaping the Future with Akita Winds—A New Step Towards Clean Energy,” OKAOGE combines technology, sustainability, and community engagement to advance Japan’s renewable energy ambitions. As the 315 MW Akita Offshore Wind Project approaches operation in June 2028, it symbolizes Japan’s commitment to offshore renewable energy and the empowerment of local economies.
