The OECD Shipbuilding Committee Peer Review of the Japanese shipbuilding industry provides a comprehensive analysis of its structure, market trends, and national strategies. The report highlights Japan’s role as the world’s third-largest shipbuilder and its strategic focus on high-value-added, eco-friendly vessels. While identifying structural challenges like an aging workforce and high production costs, the review emphasizes growth opportunities through Digital Transformation (DX) and Green Transformation (GX), particularly in zero-emission vessel development and smart manufacturing. The report is structured into three parts: a global perspective on Japan’s market standing, an analysis of the integrated shipbuilding and marine equipment ecosystem, and a SWOT-based assessment of the industry’s competitiveness.
Peer Review of the Japanese Shipbuilding Industry 2026
Abstract
Executive summary
In the early 2020s, global shipbuilding completions and orders rebounded moderately from the mid-2010s downturn, but levels remained well below the 2008–2011 peak. Japan’s share of global completions and orders gradually declined to around 11% in 2024, maintaining its position as the third-largest shipbuilding nation after China and Korea. Despite this reduction, Japanese shipbuilders retain strong positions in high-value and technologically advanced vessels, including LNG-fuelled, methanol-ready, and hybrid-propulsion ships, supported by high engineering capacity and rigorous quality standards.
The Japanese government and shipbuilding sector are working together to strengthen the industry's competitiveness through technological innovation, digital transformation, and decarbonisation. Japan is promoting the development of next-generation and zero-emission vessels, while shipbuilders are enhancing productivity through automation and advanced design technologies. At the same time, the industry is seeking to secure skilled workforce, restructure supply chains, and improve operational efficiency to sustain its position to strengthen its position in the global shipbuilding industry.
Japan’s shipbuilding sector continues to face structural cost disadvantages, notably higher labour, land, and energy costs compared with neighbouring competitors. The prolonged appreciation of the yen during the 2010s eroded export competitiveness; however, recent yen depreciation has partially offset these pressures. Japanese yards have responded by shifting toward smart manufacturing and automation, integrating modular construction and digital shipyard management systems to enhance productivity without expanding physical capacity.
Following the global financial crisis, Japan’s orderbook and completions contracted sharply as trade slowed and ship finance tightened. The sector underwent extensive restructuring and consolidation, particularly among mid-sized yards, while leading builders—Imabari, Mitsubishi, and Tsuneishi—maintained output in bulkers, PCCs, and LNG carriers. Through the 2020s, Japanese shipbuilders further diversified into dual-fuel, methanol-capable, and energy-efficient designs, aligning with global decarbonisation trends and ESG-linked investment criteria.
The Japanese marine equipment industry remains a key pillar of industrial competitiveness, characterised by high domestic integration (≈92%), technological leadership, and export strength in diesel engines, outboard motors, propulsion control systems, and energy-saving devices. In 2024, total production value reached JPY 470 billion, with diesel engine output alone valued at JPY 264 billion. Japan’s exports of outboard motors and reciprocating engines account for more than 80% of total marine equipment exports, primarily destined for the United States, Southeast Asia, and Europe.
Japan is pursuing a comprehensive green transition strategy, anchored in the Green Growth Strategy toward Carbon Neutrality by 2050 and the Green Innovation Fund supporting research, development, and demonstration of next-generation vessels. Public programmes promote R&D on hydrogen- and ammonia-fuelled propulsion, fuel-conversion systems, and autonomous operations, ensuring Japan’s continued leadership in clean maritime technologies.
Labour dynamics remain a structural concern. Total shipbuilding employment fell from over 90 000 in 2016 to 70 300 in 2023, with foreign workers now representing 5–10% of the workforce—primarily from the Philippines, Indonesia, and Viet Nam. While the share of skilled and design staff has increased, the inflow of younger workers has slowed, posing challenges for long-term labour sustainability.
Japanese repair yards maintain stable activity levels, primarily serving domestic clients. Between 2018 and 2024, over 96% of repairs were commissioned by Japanese owners. Although energy-saving retrofits remain limited, notable progress includes the world’s first ammonia-propulsion conversion in 2023 by Keihin Dock Co., demonstrating Japan’s capability in advanced retrofitting and alternative-fuel integration.
The shipbuilding industry continues to play a pivotal role in Japan’s manufacturing base and export performance. The sector contributes to regional economies through dense industrial networks in Hiroshima, Ehime, and Nagasaki prefectures, closely linked with the marine equipment, steel, and logistics industries. Japan’s long-term industrial vision emphasises digitalisation, decarbonisation, and global competitiveness, aiming to secure sustainable growth through innovation and international collaboration.
The Japanese government actively supports these goals through Ministry of Land, Infrastructure, Transport and Tourism (MLIT) policies focusing on technological innovation, ship finance facilitation via Japan Bank for International Cooperation (JBIC) and Nippon Export and Investment Insurance (NEXI), and collaborative frameworks between industry and academia. Strategic initiatives such as the Smart Ship Project, Zero Emission Ship Project, and Maritime DX Consortium highlight Japan’s efforts to combine engineering excellence with green and digital transitions.
The SWOT analysis for the Japanese shipbuilding industry is presented in Chapter 5, outlining Japan’s strengths in engineering and technology, weaknesses in cost structure and labour pipeline, opportunities in alternative-fuel markets, and threats from global overcapacity and intensified regional competition. The analysis highlights Japan’s strong technological base and stable industrial ecosystem but also underscores structural challenges such as high production costs and workforce constraints. It suggests that Japan’s future competitiveness will depend on accelerating innovation and adapting to the global transition toward green and digital shipbuilding.
