DeepWind delivers key updates on Japan’s offshore wind sector in English every week.
This article provides a full digest of the major developments in 2025.
August
- Policy: Floating wind target clarified – 15 GW by 2040, EEZ development to accelerate
- Industry: Mitsubishi-led Consortium Exits Three Offshore Wind Projects
- Technology: MODEC Secures AiP for TLP Floating Wind Concept
August 2025 marked a turning point where Japan’s offshore wind market advanced on three fronts: clearer policy direction, industry suprising, and new design progress.
September
September 2025 highlighted both the challenges of Japan’s offshore wind business environment and the government’s additional support measures. Triggered by Mitsubishi Corporation’s withdrawal, re-tendering efforts accelerated in Akita and Chiba, while surveys revealed significant impacts on local supply chains. In response, the government moved to extend sea area utilization beyond 30 years and revise tender rules to ensure long-term project viability.
At the same time, regional initiatives advanced steadily. Kitakyushu announced plans for a floating wind hub at Hibikinada, while Fukui Prefecture estimated an economic ripple effect of ¥123 billion and nearly 7,000 new jobs from the planned Awara offshore wind project.
On the technology front, the unveiling of a new cable-laying vessel and international collaboration between Japan’s floating wind consortium and Scotland’s EMEC reflected progress in infrastructure and R&D capacity. Even under rising costs and uncertain market conditions, Japan is pushing forward with both fixed-bottom and floating wind opportunities.
October
October 2025 marked a turning point for Japan’s offshore wind industry, with Akita once again at the center of attention.
The World Offshore Wind Summit Japan 2025 highlighted themes such as floating technology, supply chain development, and workforce training—signaling that Japan’s offshore wind sector is entering a new phase of maturity.
From an industrial perspective, several key developments stood out: Furukawa Electric’s new subsea cable plant, DENZAI E&C’s assembly base in Akita, and FibreMax’s plan to establish a production hub all underscored Japan’s growing capacity to localize manufacturing and installation activities. Together, these moves suggest the gradual emergence of a regional industrial cluster across Tohoku and Hokkaido.
At the same time, the restructuring of the Choshi offshore wind project illustrated the challenges of developer transitions and project continuity. Yet, Japan’s domestic ecosystem is strengthening—exemplified by FLOWRA’s ¥6 billion national R&D program for floating wind and expanded O&M collaborations among local engineering firms.
