Introduction: Japan’s Ambitious Targets and Policy Imperatives
Japan has set ambitious offshore wind capacity targets of 10 GW by 2030 and 30–45 GW by 2040 as part of its broader carbon neutrality goal by 2050. Achieving these goals requires a robust and evolving policy framework covering legal foundations, economic incentives, project selection procedures, and certification systems.

1. Strategic Energy Policy and Long-Term Vision
Offshore wind is positioned as a key pillar in Japan’s long-term energy strategy, including the Strategic Energy Plan and the Global Warming Countermeasures Plan. These documents serve as compasses guiding Japan’s energy mix and decarbonization roadmap.

2. Centralized Approach: Streamlined Policy Implementation
Japan has adopted a centralized approach to streamline the selection and implementation of offshore wind projects. Under this system, the government identifies promotion zones and conducts public tenders, increasing transparency, reducing risk, and improving investor confidence.

3. Legal Framework and the Promotion Zone System
The Marine Renewable Energy Act, often referred to as the Promotion Zone Law, forms the legal foundation for offshore wind development. The act allows the designation of sea areas for exclusive use through public bidding, coordinated by METI and MLIT.

4. Project Selection: Scoring System and Bid Evaluation
Japan uses a scoring system to evaluate public tenders in designated promotion zones. Bids are assessed based on two main components: price and feasibility. The feasibility score further includes detailed criteria such as project execution capacity, financial planning, decommissioning strategies, and stakeholder engagement.

5. Support Mechanisms: FIT and FIP Schemes
Japan has implemented Feed-in Tariff (FIT) and Feed-in Premium (FIP) schemes to support renewable energy deployment. While FIT ensures fixed pricing, FIP introduces market exposure with additional premiums. The shift toward FIP raises the need for more sophisticated risk management.

6. Regulatory and Certification Challenges
Offshore wind projects, especially floating types, must meet strict safety and certification standards. Japan’s regulatory landscape includes construction approvals, environmental permits, and METI certification. Floating projects face additional complexity regarding structural stability and mooring system safety.

7. Policy Evolution and Risk Management
While Japan’s policy framework has advanced rapidly, emerging risks remain. These include transmission bottlenecks, potential suspension of bidding rounds, and changes to financial support mechanisms. Japan’s government continues to respond by updating regulations and improving planning predictability.

Conclusion: What’s Next for Japan’s Offshore Wind Policy?
Japan’s offshore wind policy framework is a layered system that balances centralized control with legal clarity and financial incentives. As the country aims for large-scale deployment, the evolution of this framework will play a critical role in determining success. Stakeholders must stay informed of policy changes, regulatory updates, and market dynamics to navigate this complex landscape.
