簡介目錄

2025年，日本離岸風力發電市場規模達9.6575億美元。展望未來，IMARC Group預測，到2034年，該市場規模將達到26.4522億美元，2026年至2034年的複合年成長率（CAGR）為11.85%。這一市場成長主要歸功於日本專屬經濟區（EEZ）內浮動式風力發電離岸風力發電開發的擴張。 2024年相關法律修正案的訂定，使得日本專屬經濟區內大片深海域適宜興建漂浮風電場。此外，成功完成的多輪大型競標吸引了許多國內外業者的參與，也展現了強勁的市場勢頭，是支撐日本離岸風力發電市場佔有率的關鍵因素。

日本離岸風力發電市場的發展趨勢：

將離岸風電開發擴展到專屬經濟區（EEZ）

在日本，由於法律改革擴大了專屬經濟區（EEZ）內領海以外的開發機遇，離岸風力發電裝置容量正經歷變革性成長。 2024年1月，日本政府核准了《海上可再生能源發電設施開發利用海域促進法》的重大修訂，允許在22公里領海邊界以外的專屬經濟區內指定和競標離岸風力發電區域。這項修訂意義重大，因為日本的專屬經濟區面積約為其陸地面積的12倍，領海面積的10倍，涵蓋了該國大部分離岸風力發電潛力，僅浮體式設施的裝機容量就估計超過400吉瓦。此次改革引入了分階段核准流程，部分借鏡了英國的做法。開發商首先獲得長達30年的租賃權，然後在與當地社區和漁業相關人員協商後，獲得最終的建設許可。這個法規結構充分考慮了日本的地理挑戰，包括其深水近岸海域和陡峭的大陸棚。傳統的固定式離岸風電設施只能在有限的海岸區域內安裝。專屬經濟區（EEZ）的擴大對於浮體式海上風電技術尤其重要，而漂浮式離岸風電技術對於實現日本雄心勃勃的離岸風力發電目標至關重要，即到2030年達到10吉瓦，到2040年達到30-45吉瓦。包括世界風力發電理事會在內的相關人員對此進展表示歡迎，認為這對於增強日本的能源獨立性和韌性以及創造重要的全球產業機會至關重要。

透過產業合作開發浮體式海上風電技術

日本離岸風電市場的成長正得益於前所未有的產業合作，而這種合作的重點在於開發浮體式海上風電技術。 2024年3月，日本成立了浮體式海上風電技術研究協會（FLOWRA），這是一個由14家創始公司組成的專業聯盟。到2024年7月，該協會已發展至21家公司，其中包括日本電力集團（JERA）、關西電力、東京燃氣、東北電力和丸紅海上風電開發株式會社等主要電力公司。 FLOWRA的夥伴關係模式旨在解決單一開發商無法獨自應對的根本性挑戰，例如設計能夠抵禦日本惡劣天氣和海況的基礎設施、建造合適的港口基礎設施和供應鏈，以及應對複雜的法規結構。該協會已與美國能源局、國家可再生能源實驗室、國家海洋能源管理局和英國海上可再生能源彈射器等海外機構建立了正式合作關係，從而促進技術轉移和知識交流。同時，日本能源公司正進行策略性國際投資，以獲取浮體式海上風電技術的營運經驗。 2024年8月，東京瓦斯收購了位於葡萄牙的浮體式海上離岸風電場WindFloat Atlantic 21.2%的股份，這是該公司首次直接投資海外浮體式海上風電計劃。這項策略性投資將使東京燃氣獲得浮體式海上風電場營運和維護方面的實務經驗，並將其應用於日本國內市場的發展。這些合作舉措體現了日本國內能源產業普遍意識到，浮體式海上風電是日本能源轉型中的關鍵技術。

The Japan offshore wind energy market size reached USD 965.75 Million in 2025 . Looking forward, IMARC Group expects the market to reach USD 2,645.22 Million by 2034 , exhibiting a growth rate (CAGR) of 11.85% during 2026-2034 . The market is driven by the expansion of offshore wind development into Japan's Exclusive Economic Zones following legislative reforms in 2024, which unlocked vast deepwater areas suitable for floating wind farms. Furthermore, successful completion of major auction rounds attracting both domestic and international players demonstrates strong market momentum, supporting the Japan offshore wind energy market share.

JAPAN OFFSHORE WIND ENERGY MARKET TRENDS:

Expansion of Offshore Wind Development into Exclusive Economic Zones

Japan is experiencing transformative growth in offshore wind capacity through legislative reforms that expand development opportunities beyond territorial waters into the country's Exclusive Economic Zones. In January 2024, the Japanese government approved a major legal reform amending the Act on Promoting the Utilization of Sea Areas for Development of Marine Renewable Energy Power Generation Facilities, allowing designation and tendering of offshore wind areas in the EEZ beyond the 22-kilometer territorial waters boundary. This legislative milestone is critically important because Japan's EEZ is approximately 12 times larger than its landmass and 10 times the size of its territorial sea, containing the vast majority of the nation's offshore wind potential estimated at over 400 GW for floating installations alone. The reform introduces a structured two-stage approval process modeled partly on UK practices, where developers first secure leasing rights for up to 30 years, then engage in stakeholder negotiations with local communities and fisheries before receiving final construction permits. This regulatory framework addresses Japan's unique geographic challenges, as the country's deep coastal waters and steep continental shelf make traditional fixed-bottom installations feasible only in limited nearshore areas. The EEZ expansion is particularly significant for floating offshore wind technology, which is essential for Japan to achieve its ambitious targets of 10 GW of offshore wind capacity by 2030 and 30-45 GW by 2040. Industry stakeholders, including the Global Wind Energy Council, welcomed this development as crucial for increasing Japan's energy autonomy and resilience while creating important global industrial opportunities.

Advancement of Floating Offshore Wind Technology Through Industry Collaboration

The Japan offshore wind energy market growth is being accelerated through unprecedented industry collaboration focused on floating offshore wind technology development. In March 2024, Japan launched the Floating Offshore Wind Technology Research Association, a specialized consortium of 14 founding companies that expanded to 21 members by July 2024, including major utilities JERA, Kansai Electric Power, Tokyo Gas, Tohoku Electric Power, and Marubeni Offshore Wind Development Corporation. FLOWRA's collaborative approach addresses fundamental challenges that individual developers cannot solve alone, including designing infrastructure capable of withstanding Japan's severe weather and sea conditions, developing adequate port infrastructure and supply chains, and navigating complex regulatory frameworks. The association has already established formal partnerships with overseas organizations including the U.S. Department of Energy, National Renewable Energy Laboratory, Bureau of Ocean Energy Management, and the UK's Offshore Renewable Energy Catapult, facilitating technology transfer and knowledge exchange. Concurrently, Japanese energy companies are making strategic international investments to gain operational expertise in floating wind technology. In August 2024, Tokyo Gas acquired a 21.2 percent stake in Portugal's WindFloat Atlantic floating offshore wind farm, marking the company's first direct investment in an overseas floating wind project. This strategic investment allows Tokyo Gas to gain practical experience with floating wind operations and maintenance that can be applied to Japan's domestic market development. These collaborative initiatives reflect recognition across Japan's energy sector that floating offshore wind represents a critical technology for the nation's energy transition.
