Japan is making significant strides in renewable energy with projects like the Goto Floating Offshore Wind Farm. Located off the coast of Goto City, Nagasaki Prefecture, this ambitious initiative demonstrates Japan’s commitment to innovative offshore wind technologies and sustainable energy solutions. This post explores the project’s scale, implementation, and its broader impact on the local economy and environment.
Project Overview
| Project name | Goto City Offshore Floating Wind Power Project |
| Developer | Goto Floating Wind Farm LLC |
| Stakeholders | Toda Corporation, ENEOS, Osaka Gas, INPEX, Kansai Electric Power, Chubu Electric Power |
| Location | Offshore Goto City, Nagasaki Prefecture |
| Type | Floating Offshore Wind Power (Hybrid Spar-Type, Three-Point Mooring System) |
| WTG | Hitachi |
| Price | 36 JPY/kWh |
| Capacity | 16.8 MW (2.1 MW × 8 turbines) |
| Start of Construction | July 2020 |
| COD | January 2026 – december 2043 |
Notes: Change in COD
According to Toda Corporation, COD of this project was originally scheduled for January 2024, but due to delays in the construction process caused by defects found in the floating structure during construction, an application was submitted to change the public occupancy plan to change the COD to January 2026, and was approved by METI on September 22, 2023.

Key Features of the Project
1. Innovative Technology
The hybrid spar-type floating platform used in this project is uniquely designed to withstand deep waters and typhoon-prone regions. Each turbine, with a capacity of 2,100 kW, incorporates cutting-edge engineering to maximize efficiency and durability.
2. Construction Plan
- Manufacturing:
Steel components are constructed in Nagasaki Prefecture’s shipyards, leveraging local expertise in maritime engineering.
Concrete float components are fabricated locally to boost cost efficiency and involve regional construction firms. - Assembly and Installation:
Components are assembled at the Fukue Port in Goto City before being transported to designated offshore sites for installation.
3. Economic and Regional Impact
The project actively contributes to the local economy through:
- Procurement of construction materials and services from regional businesses.
- Employment opportunities during construction and operation phases.
- Strengthening local supply chains and maritime infrastructure.
4. Environmental and Social Harmony
This project includes measures to monitor and mitigate environmental impacts, such as:
- Ongoing assessments of marine ecosystems, including fish populations and seabird activities.
- Collaborative efforts with local fishermen and stakeholders to ensure coexistence with existing marine activities.
Long-Term Vision
The Goto City Offshore Floating Wind Farm is part of Japan’s broader strategy to achieve carbon neutrality by 2050. By setting a benchmark in floating offshore wind technology, the project aims to attract further investments and inspire similar developments in other regions.
Conclusion
The Goto Floating Offshore Wind Farm exemplifies Japan’s innovative approach to renewable energy. Through technological advancements, local collaborations, and environmental stewardship, the project paves the way for a sustainable and energy-independent future.
