We are excited to partner with the Renewable Energy Institute to advance offshore wind in Japan through a cost study of fixed-bottom offshore wind and its cost-out potential to 2040.
Our joint work aims to:
🔹Clarify the current cost gap between Japan and Europe for fixed-bottom offshore wind,
🔹Identify the main drivers of this cost gap by offshore wind component,
🔹And demonstrate whether Japan’s higher costs are reducible through regulatory rationalization, market expansion, and supply-chain development.
Japan is poised to become an important offshore wind market in the coming decades. Fixed and floating offshore wind build-out is expected to grow steadily after 2030 to around 14 GW by 2040, according to Aegir Insights’ Market Forecast, making it the second-largest installed capacity in Asia-Pacific after South Korea.

Following Mitsubishi’s withdrawal from its Round 1 auction projects a few months ago, the Japanese government has recently proposed policy changes to improve the business case for the Round 2 and 3 winning projects and help ensure project completion. The package also includes further reforms for future auction rounds, signaling a willingness to support an offshore wind sector under pressure.
Aegir Insights’ clients can get a detailed overview of the Japanese offshore wind market in our new Japan Market Playbook on the Aegir Platform (accessible here).
