簡介目錄

2025年，日本離岸風力發電市場規模達24億美元。 IMARC Group預測，到2034年，該市場規模將達到104億美元，2026年至2034年的複合年成長率（CAGR）為17.98%。政府實現碳中和的目標、有利的風力條件、技術成本的下降、能源安全方面的考量，以及透過上網電價補貼（FIT）和競標機制提供的政策支持，都是推動日本離岸風力發電市場佔有率成長的因素。沿海地區的地理條件和產業創新也是離岸風力發電擴張的重要驅動力。

日本離岸風力發電市場的發展趨勢：

宏觀經濟壓力迫使計劃重新評估

由於通貨膨脹加劇、日圓疲軟、利率上升以及持續的供應鏈中斷，日本離岸風力發電產業仍在繼續發展，這體現了該產業在支持日本能源安全和脫碳目標方面發揮的關鍵作用。相關人員在調整其業務框架和投資策略，以應對當前形勢，同時保持清潔能源擴張的勢頭。離岸風電是國家議程上的優先事項，目前的努力旨在平衡眼前的經濟現實與長期的可再生能源目標。這段時期並非發展停滯，而是策略調整期。這些因素正在加速日本離岸風力發電市場的成長。例如，2025年2月，三菱商事株式會社因宏觀經濟變化（包括通貨膨脹、日圓疲軟、供應鏈受限和利率上升）而對其在秋田縣和千葉縣的離岸風力發電計劃進行了審查。 2021年選定的計劃涵蓋能代、三根、男鹿、由利本莊和銚子等區域。三菱商事株式會社在繼續推進專案開發的同時，也重新評估產業計畫並探索未來的發展方向。離岸風電仍然是日本確保能源穩定供應和實現碳中和目標的核心組成部分。

擴大浮體式海上風電領域的創新

日本正透過在秋田縣南部沿海地區啟動一項新計劃，推進其浮體式海上風電裝置容量。該計劃由政府資助，重點是在模組化半潛式平台上安裝高功率渦輪機。它融合了最佳化的錨碇系統、協調的船舶作業以及用於持續性能監測的數位雙胞胎技術。該示範項目旨在降低成本，並為浮體式風電基礎設施的廣泛部署奠定基礎。透過結合技術創新和即時數位監測，日本旨在提升深海域的可再生能源能力。這是日本持續努力擴大清潔能源來源和增強能源韌性的一部分。例如，2024年10月，秋田縣南部沿海地區啟動了一個大型離岸風電計劃。該計劃由丸紅株式會社和日本海洋聯合公司主導，計畫在2029年安裝兩台總裝置容量超過15兆瓦的浮體式風力發電機。該計畫由政府資助，強調透過模組化半潛式結構、最佳化的錨碇系統、數位雙胞胎監測和協調的船舶作業來降低成本。示範試驗將持續到 2031 年 3 月，旨在有效擴大日本浮體式海上風力發電能力。

The Japan offshore wind power market size reached USD 2.4 Billion in 2025. Looking forward, IMARC Group expects the market to reach USD 10.4 Billion by 2034, exhibiting a growth rate (CAGR) of 17.98% during 2026-2034. Government targets for carbon neutrality, favorable wind conditions, declining technology costs, energy security concerns, and policy support through feed-in tariffs and auctions are some of the factors contributing to Japan offshore wind power market share. Coastal geography and industrial innovation also encourage offshore wind energy expansion.

JAPAN OFFSHORE WIND POWER MARKET TRENDS:

Macroeconomic Pressures Prompting Project Reassessment

Offshore wind initiatives in Japan are undergoing strategic realignment due to rising inflation, a weaker yen, elevated interest rates, and ongoing supply chain disruptions. Development plans are being re-evaluated in response to these financial and logistical challenges. Despite these pressures, progress continues, reflecting the sector's vital role in supporting the country's energy security and decarbonization goals. Stakeholders are adjusting business frameworks and investment approaches to navigate the current environment while maintaining momentum in clean energy expansion. Offshore wind remains a priority in the national agenda, and current efforts aim to balance immediate economic realities with long-term renewable power ambitions. This period marks a recalibration phase rather than a retreat from development. These factors are intensifying the Japan offshore wind power market growth. For example, in February 2025, Mitsubishi Corporation reviewed its offshore wind power projects in Akita and Chiba due to macroeconomic shifts, including inflation, yen depreciation, supply chain constraints, and rising interest rates. Selected in 2021, the projects span Noshiro, Mitane, Oga, Yurihonjo, and Choshi. Mitsubishi continues development efforts while reassessing business plans to determine next steps. Offshore wind remains central to Japan's energy stability and carbon neutrality goals.

Scaling Up Floating Wind Innovation

Japan is advancing its floating offshore wind capabilities through a new initiative off the southern coast of Akita. Supported by government funding, the project focuses on installing high-capacity turbines using modular semisubmersible platforms. It incorporates optimized mooring systems, synchronized vessel operations, and digital twin technology for continuous performance monitoring. The initiative serves as a demonstration effort aimed at reducing costs and building a foundation for broader deployment of floating wind infrastructure. By combining engineering innovation with real-time digital oversight, the project is designed to strengthen Japan's ability to utilize deeper offshore areas for renewable energy. This move reflects the country's ongoing efforts to expand clean power sources and increase energy resilience. For instance, in October 2024, Japan launched a major offshore wind initiative near southern Akita. Led by Marubeni and Japan Marine United, the project would install two 15+ MW floating turbines by 2029. Backed by government funding, it emphasizes cost reduction via modular semisubmersible structures, optimized mooring, digital twin monitoring, and synchronized vessel operations. The demonstration will run until March 2031, aiming to scale Japan's floating wind capabilities efficiently.
