In February 2024, TSMC opened its first chip fabrication plant in Kumamoto, Japan. Morris Chang, the 92-year-old founder of Taiwan's semiconductor giant, flew in for the ceremony and remarked that the new factory would, he believed and hoped, start a renaissance of semiconductors in Japan. The Japanese government had committed $8 billion in subsidies to make the facility happen. Toyota, Sony, and Denso had all taken equity stakes in the joint venture. Forty-four supplier companies had already begun clustering around the site. None of this happened because TSMC suddenly developed an affection for Kyushu. It happened because the US-China technology war made Taiwan's geographic concentration an existential risk for the entire global semiconductor supply chain, and Japan was the most credible alternative geography on the board. That is the investment thesis in miniature: Japan is not simply a passive beneficiary of supply chain diversification. It is the designated fallback position for the industries the world most needs to keep out of harm's way.
The China-Plus-One strategy is not new. The Japanese government first proposed it to its multinationals as early as 2005, encouraging them to hedge production exposure beyond China. The response at the time was lukewarm. Chinese manufacturing was cheap, efficient, and deeply integrated with Japanese corporate supply chains. The political risk felt theoretical. Then three things happened in rapid succession: the US-China trade war starting in 2018 imposed 25% punitive tariffs on Chinese exports to the United States, destroying the economics of using China as an export platform for the American market; the COVID-19 pandemic of 2020 shut down Chinese production capacity across multiple industries simultaneously and revealed exactly how thin the margin of supply chain resilience had become; and the subsequent technology export controls — coordinated between the US, Europe, Japan, and the Netherlands — transformed supply chain diversification from a corporate preference into a geopolitical obligation. This time, the response from Japanese companies has been anything but lukewarm.1
Why Japan, and not somewhere else
The obvious alternative supply chain geographies — Vietnam, India, Mexico, Malaysia — get considerably more headline attention than Japan when the de-sinicisation story is told. That is partly because the story of cheap labour migration from China to Vietnam reads cleanly as a conventional manufacturing relocation narrative. Japan does not fit that template. Japanese labour is expensive, Japanese real estate is constrained, and Japan's bureaucratic culture does not move at startup speed. The case for Japan as a supply chain beneficiary is not about cost. It is about capability.
Japan controls chokepoints in global manufacturing that exist nowhere else on earth. In semiconductor equipment and materials alone, the numbers are startling: Japan holds approximately 88% of global market share in semiconductor coater and developer equipment, 53% in silicon wafers, and 50% in photoresists.2 These are not commodity inputs. A photoresist is a light-sensitive chemical layer applied to silicon wafers during the patterning process. The chemistry required to produce photoresists capable of working with extreme ultraviolet lithography, the process required for the most advanced chips, took decades to develop and is concentrated in a handful of Japanese companies — primarily JSR, Tokyo Ohka Kogyo, and Shin-Etsu Chemical. The same pattern holds across the equipment ecosystem. Tokyo Electron, the world's third-largest semiconductor equipment company, manufactures tools that have no readily available substitutes. When the US and its allies decided to restrict China's access to advanced semiconductor manufacturing capability, the practical effect was partly delivered through Japanese companies who make inputs that China cannot easily replicate domestically.
This is what makes Japan's position in the de-sinicisation trade qualitatively different from Vietnam's or India's. Vietnam captures relocated assembly operations for consumer electronics. That is real and growing, but it is also competitively contested and subject to the same political risk management that drove diversification from China in the first place. Japan provides the substrate inputs — the materials, the chemicals, the precision equipment — without which the chip itself cannot be manufactured at all. This is a different order of strategic importance, and it commands a different valuation premium over time.
The semiconductor revival: ambition meets subsidy
Japan's semiconductor story has a painful history that makes the current chapter more interesting. In 1988, Japanese companies controlled 51% of worldwide chip sales, dominating memory production and manufacturing equipment. By 2019, that share had declined to approximately 10%, the victim of a combination of the 1986 US-Japan Semiconductor Agreement, which constrained Japanese pricing and opened market access to American competitors, and the failure to adapt to the fabless model that allowed TSMC and Samsung to build scale through contract manufacturing while Japanese firms clung to integrated, vertically-oriented structures.3 The industry that had once defined Japanese technological leadership had become a series of ageing fabs, shrinking market shares, and corporate consolidations that served to manage decline rather than reverse it.
The government response since 2022 has been aggressive by any historical standard. Japan committed 0.71% of GDP — approximately $25.7 billion — to semiconductor subsidies over the three-year period from 2022 to 2025, a proportion significantly higher than Germany's 0.41%, the United States' 0.21%, or France's 0.20%.2 The strategy has two tracks: attracting foreign fabs to build advanced manufacturing in Japan, and building a domestic advanced logic champion from scratch. The first track produced TSMC's Kumamoto plant. The second produced Rapidus.
Rapidus is the more audacious bet. It was established in 2022 as a consortium of eight Japanese companies — Denso, Kioxia, MUFG Bank, NEC, NTT, SoftBank, Sony, and Toyota — with the explicit goal of mass-producing 2-nanometer chips by 2027. The technological ambition is startling. Japan's most advanced commercially manufactured chip at the time of Rapidus's founding was at the 40nm node. The company is attempting to jump from 40nm to 2nm in five years, bypassing every intermediate generation of manufacturing process. To make this possible, Rapidus partnered with IBM for technology development and sent over one hundred engineers to IBM's research centre in Albany, New York. The government has committed approximately $11 billion to the project. A pilot production line in Chitose, Hokkaido became operational in April 2025.4
Japan's semiconductor strategy is not a catch-up play. It is an attempt to arrive at the frontier simultaneously with TSMC and Samsung — not by following their path, but by leaping over the generations they traversed.
Whether Rapidus succeeds in mass production by 2027 is genuinely uncertain — the technical challenges are formidable and the commercial viability requires customers who will commit to a new foundry with no track record at scale. But the investment thesis does not depend on Rapidus succeeding. It depends on the ecosystem around it. TSMC's expansion in Kumamoto is already attracting the cluster of 44 supplier companies that began organising before Fab 1 was operational. The material science companies — Shin-Etsu Chemical, Sumco, JSR — are expanding capacity. Tokyo Electron is benefitting from every new fab opening, regardless of operator. The government subsidy programme has a supply chain resilience fund established in February 2024 with initial capital of 2.75 trillion yen, designed to support both chip production and the broader materials and equipment ecosystem.5 The tide is rising for the entire sector.
Corporate Japan's China+1 pivot: what the FDI data shows
Beyond semiconductors, Japanese multinationals across a wide range of industries have been executing supply chain diversification strategies with a seriousness that was absent in the 2005 version of this story. The evidence is visible in foreign direct investment flows, production relocation announcements, and the explicit strategic language coming from corporate boards.
Tamura, an electronics components maker, has been scaling back its China production exposure by up to 30%, with expanded manufacturing capacity going to Europe and Mexico, targeting completion by early 2028. TDK is relocating smartphone battery cell manufacturing from China to India. Murata, one of the world's largest capacitor manufacturers, plans to open its first multilayer ceramic capacitor plant in India in fiscal 2026. Meiko, a printed circuit board supplier for Apple's iPhone supply chain, commissioned a 50 billion yen factory in Vietnam in 2025 to support assembly operations shifting from China to India and Southeast Asia.6 These are not symbolic gestures. They represent capital allocation decisions made at the board level, driven by a combination of US tariff pressure on Chinese-made goods, the technology export control regime, and the genuine operational lessons learned from COVID-era supply chain disruption.
The CEPR analysis of Japanese multinational investment patterns from 2009 to 2022 confirms this directional shift clearly: Japanese companies have been diversifying supply chain exposure away from China toward ASEAN economies without fully abandoning China entirely.7 The practical implication is a dual-track strategy. China remains important as a domestic consumer market — 54% of Japanese Chamber of Commerce members in China planned to maintain or increase investment in 2024, citing the scale of the local market. But the role of China as a manufacturing and export platform for third markets has been diminishing, and the production that is moving is moving into geographies where Japan either has strong existing commercial relationships, manufacturing cost advantages relative to alternatives, or, in the domestic case, government support that makes relocating home economically viable.
The Economic Security Promotion Act: when policy becomes mandate
The 2022 Economic Security Promotion Act is not a well-known piece of legislation outside Japan, but it may be the single most consequential piece of industrial policy enacted in the country in a generation. Passed by the Diet in May 2022, it mandates the Japanese government to secure supply chains for critical materials and maintain the stability of key infrastructure. In concrete terms, it gives METI — the Ministry of Economy, Trade and Industry — explicit authority to intervene in private sector supply chain decisions in the name of national security, provides a legal framework for government subsidies to strategic industries, and creates a security clearance system for private sector access to sensitive technology and government information.5
The significance of this for investors is that supply chain diversification is no longer merely a corporate strategic preference in Japan. It is backed by a legal and financial apparatus that creates sustained incentives for relocation, domestic production expansion, and technology partnership formation. The supply chain resilience fund established under this architecture — 2.75 trillion yen in initial capital — dwarfs anything previously deployed for this purpose. The coordination mechanism between METI, the Development Bank of Japan, JBIC, and NEXI creates interlocking financial support for the full stack of supply chain investment, from equity to export insurance.
METI's own framing of the semiconductor strategy is explicit: it is a national project designed to ensure Japan remains strategically essential and strategically independent amid what they call the conflict for technological hegemony between the United States and China. That language is not bureaucratic boilerplate. It reflects a genuine strategic calculation that the window for establishing Japanese relevance in advanced semiconductor manufacturing is open now, because the geopolitical conditions that make Japan the preferred partner for Western supply chain diversification are present now, and that window will not remain open indefinitely.
Japan's rare earth vulnerability: the risk hiding in the thesis
The supply chain diversification thesis for Japan is compelling but not without genuine risk, and intellectual honesty requires naming it clearly. Japan's dependence on China for rare earth imports has not decreased — it has increased, from approximately 50% in 2014 to 70% in 2022, despite repeated government efforts to diversify sourcing.8 China has been progressively tightening its export control regime for strategically critical minerals — restricting exports of germanium, gallium, graphite, and antimony over the 2022-2024 period. Japan reports a disproportionately high number of products with critical supplier concentration compared to its G7 peers, particularly in machinery, organic chemicals, rare earths, and electrical components.
This is not a fatal objection to the investment thesis, but it is a real vulnerability. A Japanese corporate that has successfully diversified its manufacturing footprint away from China as an export platform remains exposed to input cost shocks if China decides to weaponise its rare earth position. The government is aware of this and has been pursuing diversification of critical mineral supply chains aggressively — bilateral agreements with Canada, Australia, and several African countries for rare earth supply security are in various stages. But execution is slow and the exposure remains real in the interim. For sector-specific positions within the Japan supply chain thesis, the mineral import dependency profile of individual companies is a variable worth understanding carefully.
The allied technology axis and Japan's diplomatic positioning
One dimension of Japan's supply chain beneficiary thesis that is frequently undervalued is the diplomatic one. Japan's 2022 National Security Strategy marked a significant shift in how the country publicly frames its geopolitical position, with explicit acknowledgement of the US-China technology rivalry and Japan's alignment with the Western camp. The coordination of semiconductor export controls — Japan joining the US and the Netherlands in restricting advanced chip manufacturing technology exports to China — was a concrete expression of that alignment with real commercial consequences for Japanese equipment companies (short-term revenue headwinds from China) and long-term strategic consequences (deep integration with the US-led technology ecosystem).
The G7 Hiroshima communiqué of May 2023 explicitly referenced supply chain resilience and de-risking from China across critical technology sectors. Japan hosted that summit and shaped much of its language on economic security. The CPTPP, which Japan has led since the United States withdrew in 2017, provides a trade architecture across eleven Pacific nations that is expressly designed to deepen economic integration among countries outside China's direct sphere of influence. Japan's bilateral investments with ASEAN nations are increasingly structured not just as manufacturing diversification plays but as elements of a broader effort to create durable, politically resilient supply networks across the Indo-Pacific.
For investors, the diplomatic positioning matters because it creates durability. The semiconductor export controls, the Economic Security Promotion Act, the TSMC and Rapidus investments, the rare earth diversification efforts — none of these would persist through a change of government if they were merely political preferences. They are now embedded in legal frameworks, treaty commitments, and bilateral capital relationships that create constituencies for their continuation. The supply chain beneficiary thesis for Japan is not a trade you need to time against an election cycle. It is a structural position that compounds over a decade.
How to position for this thesis
The Japan supply chain thesis is not a single trade. It is an investment landscape with several distinct layers, each with a different risk/return profile and time horizon.
The cleanest expression of the thesis is through the materials and equipment companies whose market position is already established and whose revenue will grow with every new fab construction globally, regardless of whether Rapidus succeeds or TSMC's Kumamoto expansion reaches 2nm. Shin-Etsu Chemical, Sumco, JSR, Tokyo Electron, and Disco Corp represent different points in this stack. Their exposure to the de-sinicisation trade is structural rather than speculative — it does not depend on any particular project succeeding, only on the global fab construction cycle, which is sustained by the combined chip investment programmes of the US, Europe, Japan, Taiwan, and South Korea running simultaneously. These companies have pricing power, high barriers to entry, and decades-long customer relationships that are not competitively challenged in any realistic scenario.
The more speculative layer is the direct semiconductor manufacturer play — Rapidus, and by extension the equity stakes held by its corporate parents. This is genuinely high-risk, high-reward. A successful Rapidus would be transformative for Japan's technology sector and would likely catalyse a rerating of the entire semiconductor ecosystem around it. A Rapidus that struggles to achieve commercial-scale production by 2027 would be an expensive lesson, though the government has demonstrated it will continue funding the project regardless of short-term setbacks. The government subsidy backstop makes this a different risk profile than a private sector technology bet, but the commercial viability question is real.
The third layer is the broader beneficiary ecosystem — the logistics companies, the real estate developers, the staffing firms, the utilities — all of which are benefitting from the concentration of semiconductor investment in specific geographies like Kumamoto and Hokkaido. This layer requires local market knowledge and sector-specific analysis, but it is where some of the least-contested valuation gaps exist.
Japan's position in the global supply chain realignment is not a story about Japan choosing to be important. It is a story about the world discovering that Japan was always critical, and that it can no longer be taken for granted.
