In July 2020, the Agency for Natural Resources and Energy (ANRE) under the METI and the Ports and Harbours Bureau under the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) designated the planned project area as one of four “promising sea areas for which preparations for organizing the council and other actions will start” under the Act on Promoting the Utilization of Sea Areas for the Development of Marine Renewable Energy Power Generation Facilities.
In April 2019, Japan’s Act of Promoting Utilization of Sea Areas in Development of Power Generation Facilities Using Maritime Renewable Energy Resources came into effect, focusing on wind power in maritime areas.
Japan aims to install 10GW of offshore wind power by 2030 and between 30 and 45GW by 2040 as part of plans to achieve carbon neutrality by 2050 that Japan's prime minister Yoshihide Suga announced in October 2020.
