Fisheries Rights and Offshore Wind Power in Choshi City, Chiba Prefecture, and Yurihonjo City, Akita Prefecture - From April 2004 to the 2020s

Fisheries Rights and Offshore Wind Power in Choshi City, Chiba Prefecture, and Yurihonjo City, Akita Prefecture - From April 2004 to the 2020s

1. Introduction of the Concept in 2004
When offshore wind power development was first considered in 2004, coordination with fisheries activities posed a significant challenge in Japan's coastal areas.
In Choshi City, Chiba Prefecture, Mitsubishi Corporation Group planned to install 31 wind turbines, proposing to use the turbine foundations as artificial reefs.
This initiative aimed to enhance cooperation with local fishermen by providing habitats for squid, rays, and other marine life.

2. Progress and Developments in the 2020s
Today, several large-scale offshore wind power projects are underway in Japan.
Off the coast of Yurihonjo City, Akita Prefecture, 65 GE turbines are being installed, targeting a total capacity of 845 MW, with the goal of commencing operations by December 2030.
The project covers 13040.4 hectares, with expectations for both renewable energy supply and regional economic contributions.

Another project off the coast of Noshiro City, Akita Prefecture, plans to install 38 turbines, aiming for a total capacity of 494 MW.
In addition, activities such as releasing juvenile sea bream and abalones have been carried out to preserve the ecosystem, promoting coexistence between fisheries and energy development.
In Choshi City, 31 turbines are already in operation, supplying sustainable energy while minimizing impacts on fisheries.

3. Challenges and Measures for Coexistence
Addressing natural disasters, such as typhoons and earthquakes, is a crucial issue for offshore wind power.
Within designated promotion areas under the Renewable Marine Area Utilization Act, guidelines considering the impact on marine ecosystems have been developed through consultation with fishermen.
Regions such as Karatsu City in Saga Prefecture are also working towards balancing fisheries conservation with energy development.

4. Prospects for the Future
The Japanese government aims to expand offshore wind power projects across various regions to achieve carbon neutrality by 2050.
Key areas, including Choshi City, Yurihonjo City, and Karatsu City, are expected to play pivotal roles in promoting the coexistence of wind power and fisheries, paving the way for a sustainable future.
