OMNI Features｜Japan's First Commercial Floating Offshore Wind Farm Enters Operation in Goto

Japan's first commercial-scale floating offshore wind farm officially began commercial operations on January 5, 2026, in waters off Goto City, Nagasaki Prefecture. The project marks a major milestone in Japan's offshore wind development, representing the country's first operational floating wind farm deployed at commercial scale.

The Goto Floating Wind Farm consists of eight turbines, each with a capacity of 2.1 MW, delivering a total installed capacity of approximately 16.8 MW. When combined with an existing fixed-bottom turbine developed earlier by Toda Corporation, the site's total capacity reaches roughly 19 MW, supplying electricity to an estimated 16,000 households in the region.

The project is developed, operated, and managed by Goto Floating Wind Farm LLC, a consortium formed by Toda Corporation, ERE Corporation (a subsidiary of ENEOS Holdings), Osaka Gas, INPEX, Kansai Electric Power (KEPCO), and Chubu Electric Power. Toda Corporation led the project's design and construction. Construction commenced in August 2022, utilizing a hybrid spar-buoy floating foundation featuring a steel upper structure and a concrete lower section—the first real-world deployment of this technology globally.

Notably, the Goto project is the first offshore wind farm in Japan to be certified by both the Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism under the Act on Promoting the Utilization of Sea Areas for Renewable Energy Generation Facilities. Japan designated the Goto offshore area as a renewable energy development zone in 2019 and selected the project developer through a public tender in 2021. As Japan advances its energy transition, the government aims to raise wind power's share of electricity generation from around 1.2% in 2024 to 4–8% by 2040, alongside expanding offshore wind capacity to more than 15 GW.
