🚢 Japan once built 40% of the world's ships. Then it fell to just 8%, overtaken by China and South Korea. Now Tokyo is fighting back with a $6.5 billion public-private investment plan, a mega-merger creating the world's 4th-largest shipbuilder, and its first-ever major warship export. Can Japan's shipbuilding industry really stage a comeback?
From Global Dominance to an 8% Market Share
In the 1990s, Japan's shipyards along the Seto Inland Sea produced roughly 40% of the world's ships. Massive tankers, bulk carriers, and container vessels slid down slipways with clockwork regularity, a testament to Japan's legendary manufacturing precision.
The decline, when it came, was swift and brutal. China poured state subsidies into its shipyards and leveraged cheap labor to undercut competitors. South Korea's chaebol conglomerates — Samsung Heavy Industries, HD Hyundai, and Hanwha Ocean — dominated the lucrative LNG carrier and mega-container ship markets with enormous scale and aggressive pricing.
By 2024, world shipbuilding order share told a stark story: China held 71%, South Korea 14%, and Japan just 8%. Annual Japanese shipbuilding output had dropped from roughly 16 million gross tons (GT) in 2019 to around 9 million GT in 2024. Japanese shipping companies, unable to get their vessels built at home, were sending 30–40% of their orders to Chinese yards.
The $6.5 Billion Roadmap: Japan Strikes Back
In December 2025, Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Cabinet Office unveiled the "Shipbuilding Industry Revival Roadmap." The headline target: double annual shipbuilding capacity to 18 million GT by 2035 and reclaim Japan's role as a global maritime manufacturing power.
The plan calls for roughly ¥1 trillion (approximately $6.5 billion) in combined public and private investment over the next decade. Here is how the money breaks down:
The government will invest about ¥380 billion ($2.45 billion), anchored by a "Shipbuilding Revival Fund" aiming for ¥350 billion ($2.26 billion) over ten years. The first three-year tranche of roughly ¥120 billion ($774 million) has already been secured in the supplementary budget. Additional allocations include ¥12 billion for economic security technology programs and ¥15 billion for AI-powered next-generation shipbuilding robots.
The private sector is expected to invest roughly ¥350 billion ($2.26 billion) in new equipment and facilities. Another ¥280 billion ($1.8 billion) will come through public-private coordination using GX transition bonds — Japan's green transformation financing tool — to support zero-emission vessel construction.
The roadmap lays out three phases: Phase 1 (2026–2028) focuses on automation and labor-saving equipment; Phase 2 (2029–2031) covers new facility construction and expansion; Phase 3 (2032–2034) brings the enlarged docks and cranes to full operation.
Critically, the plan also calls for consolidating Japan's fragmented shipbuilding industry into 1–3 major groups by around 2028, pooling design and procurement to eliminate waste and cut costs by 10%.
Mega-Merger: Japan's New Shipbuilding Giant
The consolidation is already underway. In January 2026, Japan's largest shipbuilder Imabari Shipbuilding completed its acquisition of a controlling 60% stake in the second-largest builder, Japan Marine United (JMU).
Imabari acquired shares from JFE Holdings and IHI, which had each held 35% of JMU. The combined entity produces approximately 4.69 million GT annually — surpassing South Korea's Hanwha Ocean (3.70 million GT) to become the world's fourth-largest shipbuilding group, controlling over half of Japan's domestic output.
The merger is strategically brilliant because the two companies' strengths are complementary. Imabari excels at mass-producing commercial vessels like tankers and car carriers. JMU brings expertise in high-value specialty ships — naval frigates, icebreakers, and next-generation environmental vessels. The combination creates a builder with both "scale to compete" and "technology to win."
The two companies had already been collaborating since 2021 through their joint venture Japan Shipyard (NSY), handling commercial ship design and sales. But antitrust rules had prevented them from sharing pricing and cost information. Full integration changes that — they can now operate as a truly unified force against Chinese and Korean competitors.
Historic Warship Export: Japan's Frigate Goes to Australia
In August 2025, Australia selected Japan's enhanced Mogami-class frigate — designated "New FFM" — as its next-generation general-purpose warship, beating out Germany's MEKO A-200 design in the final round. The deal covers 11 frigates worth approximately $6.5 billion, making it Japan's first-ever export of a major defense platform.
Three of the ships will be built in Japan (by Mitsubishi Heavy Industries), with the remaining eight to be constructed in Australia. Deliveries are set to begin in 2029.
Australia chose Japan for several compelling reasons. The Mogami-class features advanced stealth capability, a range of approximately 10,000 nautical miles (18,500 km) without refueling, the ability to operate with half the crew of conventional frigates, and 32 vertical launch cells for missiles — quadrupling Australia's current surface fleet firepower.
But perhaps the most decisive factor was Japan's reputation for delivering ships on time and on budget. Australia's previous frigate program — the British-designed Hunter class — had been plagued by design changes, delays, and ballooning costs, making schedule reliability a top priority.
As one analyst put it: "Japan's shipyards do superb work and deliver products on time and within budget."
US-Japan Shipbuilding Cooperation: A New Strategic Pillar
The United States, despite operating the world's most powerful navy, faces a shipbuilding crisis at home. American commercial shipbuilding capacity is estimated at roughly 1/100th of China's, and even military vessel maintenance suffers chronic backlogs.
Against this backdrop, the US and Japan reached an agreement on shipbuilding cooperation as part of their broader trade negotiations. Future plans may include repairs of US naval vessels at Japanese shipyards and sharing of shipbuilding technology. For Japan, this represents a stable, long-term source of demand and a powerful incentive to maintain cutting-edge capabilities.
This cooperation also carries significant implications for economic security. As geopolitical tensions rise in the Indo-Pacific, having allied nations maintain robust domestic shipbuilding capacity is increasingly viewed as a strategic necessity rather than merely a commercial concern.
The Challenges That Could Sink the Plan
Despite the favorable winds, Japan's shipbuilding revival faces serious headwinds.
Labor shortage is the most immediate challenge. Shipbuilding is labor-intensive work requiring skilled welders, pipefitters, and engineers. Japan's declining and aging population has made it increasingly difficult for rural shipyards to recruit young workers. The roadmap addresses this through university partnerships, vocational training programs, and expanded acceptance of foreign workers under Japan's "specified skilled worker" visa system — but these measures will take years to bear fruit.
Scale disadvantage remains a structural problem. Japanese shipyards are significantly smaller than their Chinese and Korean counterparts, unable to build multiple large vessels simultaneously. This drives up unit costs. The roadmap's target of 10% cost reduction through digitalization, robotics, and AI is ambitious but essential.
LNG carrier capability gap poses a strategic concern. Japan has largely exited the LNG carrier market — one of the most profitable segments — where South Korea dominates with specialized cryogenic technology. Rebuilding this capability requires not just shipyard investment but commitments across the entire supply chain, from engine makers to specialized material suppliers.
A Turning Tide
The global shipbuilding market is entering what may be a generational demand cycle. Tightening international emissions regulations will force massive fleet replacement with zero-emission vessels powered by ammonia, hydrogen, or other green fuels. New orders are already being booked for delivery in 2029 and beyond.
As of late 2025, Japanese shipyards held an order backlog of 622 vessels totaling approximately 30 million GT — more than three years of work. Industry leaders are cautiously optimistic, with one trade group chairman describing 2026 as a year of "favorable winds."
However, numbers alone won't determine success. Japan must navigate the consolidation process without losing the regional employment and technical skills that make its shipyards competitive. It must train a new generation of workers while automating where machines can do the job better. And it must find the right balance between commercial efficiency and the strategic imperative to maintain sovereign shipbuilding capacity.
The ¥1 trillion investment represents Japan's biggest bet on shipbuilding in decades. Whether it becomes a genuine industrial revival or remains a political roadmap on paper will depend on whether the nation can align orders, equipment, and people over the next ten years.
In Japan, hopes for a shipbuilding comeback are tempered by anxiety about the enormous gap with China and South Korea. What's the shipbuilding or maritime industry like in your country?

Reactions in Japan
As someone who's worked in a shipyard for 30 years, I feel like only the 1 trillion yen number is getting attention. Young workers are disappearing and veterans are retiring one after another. Before money, we need to figure out the people issue. Equipment means nothing without workers to operate it.
My reaction to the shipbuilding revival roadmap: finally. You could say it's too late, but infinitely better than nothing. Consolidation into 1-3 groups is already set with the Imabari-JMU alliance. The question is how Mitsubishi Heavy Industries fits in. The balance between defense and commercial ships is key.
Seeing China's 71% market share honestly feels hopeless. Like semiconductors, I worry that even with government subsidies, we can't beat China's sheer volume. But doing nothing would only widen the gap further.
The Mogami-class export to Australia could become the symbol of shipbuilding revival. An 11-ship, $6.5 billion order has huge impact. But everything hinges on meeting deadlines. If they stumble here, large overseas contracts will never come again. Mitsubishi Heavy Industries' true capability is being tested.
As someone from Imabari, I'm genuinely happy that Imabari Shipbuilding became the world's 4th largest by acquiring JMU. I grew up watching the shipyard cranes. Shipbuilding is Imabari's pride. But the reality is almost none of my classmates went to work at the shipyard... 😅
Compared to the 4 trillion yen poured into Rapidus for semiconductors, 1 trillion for shipbuilding looks small. But since it supports existing operating companies rather than building from scratch, it's more efficient. The problem is LNG carriers. Taking that specialty back from South Korea is an extremely high bar.
Shipbuilding revival isn't just industrial policy — it's economic security policy. Japan depends on imports for food and energy. People need to understand the danger of losing the ability to build our own ships. Can you buy ships from China during a conflict?
Using GX bonds for zero-emission ship construction support makes sense. No one is mass-producing ammonia or hydrogen-fueled ships yet, so there's a chance to capture first-mover advantage. But Japan tends to lose standards battles, which worries me.
I used to think shipbuilding was an old-fashioned industry, but seeing AI-powered autonomous ships and zero-emission vessels, it's totally high-tech. If the media presented it in a cooler way, it could help with recruitment too.
They casually mention expanding foreign worker acceptance, but shipyards are often in small rural towns. Housing, language support, daily life assistance... shipbuilding companies alone can't handle all this. Without local government cooperation, it'll remain a plan on paper.
The shipbuilding sector — JMU's net profit jumped 5.4x and they have 3 years of backlog secured, so near-term looks solid. But policy-driven stocks can get ahead of themselves on expectations, so be careful. Might be worth accumulating for the medium-long term though.
This reminds me of Meiji-era shipbuilding development. There's history of Mitsubishi taking over the Nagasaki Shipyard and growing it hand-in-hand with the government. Back then it was also 'catch up with the West.' It's ironic we're doing the same thing 150 years later, but Japan was supposed to be good at this public-private catch-up model.
From a shipping company perspective, Japanese shipyards are trusted for quality and fuel efficiency. But long delivery times and higher prices are issues — we end up ordering from China. If the 1 trillion yen truly improves cost competitiveness, that's welcome. But if it's 10 years away...
Our town is a shipyard town. When shipbuilding thrives, local shops and restaurants come alive too. Including related industries, the ripple effect on the regional economy is immeasurable. I wish more attention was given to the regional revitalization aspect of the roadmap.
More tax money again. Semiconductors, space, shipbuilding — everything gets 'government support.' What about the fiscal situation? We keep hearing about 'selection and concentration' but it feels like they're spraying money everywhere. Show clearer justification for spending 1 trillion yen on shipbuilding.
As a former US Navy officer, Japan strengthening its shipbuilding capacity is strategically critical for America. Our shipyards are drowning in repair backlogs, and being able to rely on allied shipbuilding infrastructure is a realistic necessity. US-Japan shipbuilding cooperation is Win-Win for both sides.
I work in Korean shipbuilding. Honestly, Japan seriously reinvesting in shipbuilding is a threat. But isn't $6.5 billion a drop in the bucket against China? China pours more than that into shipbuilding every year. Japan's real competitor isn't Korea — it's China.
As an Australian, the Mogami selection is very welcome. We were fed up with the Hunter-class delays. I trust Japanese shipyards to deliver on time. If they can't, Japanese defense exports will never be trusted again.
Chinese perspective: no matter how much Japan invests, the gap won't close. China accounts for 70% of global orders and shipbuilding is a national strategic industry. Japan's revival will likely remain limited in practice.
From the Norwegian maritime industry, Japan's investment in zero-emission vessels is noteworthy. Practical ammonia-fueled ships are a top priority in Scandinavia too. Japan's technical capability and reliability could be a differentiator in green shipping.
India is also working on strengthening shipbuilding capability, but we're still far behind Japan and Korea. Japan emphasizing cooperation with the Global South is a good sign. If it includes technology transfer, that would be a huge opportunity for India.
As a German shipbuilder, losing the Australian frigate contract to Japan hurt. The MEKO A-200 was a proven design, but we couldn't beat Mitsubishi on delivery certainty. I have to admit Japan's production management capability is truly impressive.
UK defense analyst here. The Mogami adoption by Australia could reshape Asia-Pacific security architecture. Japan and Australia using the same naval platform dramatically improves interoperability. This is a development NATO should be watching closely.
As a Filipino, Japan's strengthened shipbuilding and expanded defense exports are reassuring. With South China Sea tensions rising, allies having strong shipbuilding capability contributes to regional stability. I hope the Philippines can acquire Japanese-built vessels in the future too.
Korean-American here. Frankly, Japan's shipbuilding revival is both positive and negative for Korea. In terms of preventing Chinese dominance, Japan's effort is welcome. But if they seriously enter the LNG carrier market, it directly hits Korean interests. It's a delicate balance.
From an industrial policy perspective, Japan's shipbuilding roadmap is well-designed. The phased approach combined with the fund mechanism allows scaling investment based on results — that's rational. I think it's a model the EU's industrial policy could learn from.
Turkey also has a thriving shipbuilding industry but on a different scale from Japan. What's interesting is Japan trying to offset labor shortages with automation and robots. Turkey competes on cheap labor, but it makes you wonder which approach wins long-term.
From Singapore's maritime hub, Japan's shipbuilding revival will also impact the ship repair and maintenance market. If Japan increases building capacity, after-service networks should strengthen too. For Southeast Asian shipping companies, it means more options.
As French, I recall the 2016 submarine competition. Australia chose France over Japan then, but ultimately cancelled. Japan winning the frigate contract now likely reflects lessons learned from that experience. International defense exports require politics, technology, and diplomacy all at once.
A significant portion of Panama-flagged vessels were built in Japan. As a shipowner whose vessels transit the Panama Canal, I can tell you Japanese-built ships command premium prices even second-hand. The quality and reliability gap is real. This revival is good news for global shipping.
