TOKYO, Oct 20: Japan’s efforts to revive its semiconductor industry are facing a strategic challenge as the country prepares to support up to $21 billion in investment for two chip factories in the United States, raising questions about whether overseas commitments will strengthen or weaken its domestic technological ambitions.
The planned investment is part of a broader pledge under which Japan committed to invest $550 billion in the United States as part of a trade arrangement with the administration of US President Donald Trump. The agreement was reached in July 2025 in exchange for lower tariffs, with Washington retaining the authority to select projects eligible for investment.
The latest plans involve two semiconductor manufacturing facilities in New York state announced by GlobalFoundries, a chipmaker majority-owned by Abu Dhabi’s sovereign wealth fund, Mubadala Investment Company.
While the projects could support semiconductor manufacturing in the United States and create opportunities for Japanese equipment suppliers, analysts have questioned how much they will contribute to Japan’s own technological development.
The debate reflects a broader shift in global semiconductor policy. Governments increasingly view chip production as a matter of economic security because semiconductors are essential to artificial intelligence, telecommunications, automobiles, industrial machinery and defence systems.
Japan, which once held a dominant position in the global semiconductor industry, is seeking to rebuild its manufacturing base while maintaining close economic and security ties with the United States.
Balancing trade relations and industrial development
Japan’s participation in US semiconductor projects demonstrates the difficulty of separating trade diplomacy from industrial policy.
The investment pledge was designed to strengthen economic ties with Washington and secure more favourable tariff treatment. However, the selection of projects by the US president means that Japanese investment commitments do not necessarily translate into additional manufacturing capacity within Japan.
Nori Chiou, investment director at White Oak Capital, said the investment could increase US semiconductor production without providing Japan with the advanced technology or domestic manufacturing capabilities it seeks.
The concern is particularly important because Japan is attempting to reduce vulnerabilities in its supply chains and strengthen its position in strategically important industries.
Semiconductor production depends on a complex international network of equipment manufacturers, materials suppliers, chip designers and fabrication plants. Disruptions affecting one part of this network can create difficulties for companies and industries across several countries.
Establishing more manufacturing capacity at home could help Japan strengthen its control over essential technologies. Overseas investments, meanwhile, may improve commercial relationships and provide access to international customers without necessarily delivering the same benefits to domestic production.
A Japanese government source described the US investment commitment as a way to preserve the bilateral relationship, suggesting that the strategic value of the arrangement extends beyond its immediate industrial returns.
Japan’s economic relationship with the United States is closely linked to broader security cooperation. Maintaining that partnership remains important for Tokyo, even as policymakers seek to ensure that domestic companies retain access to critical technologies.
Lessons from Japan’s semiconductor history
Japan’s current strategy also carries historical significance.
During the 1980s, Japanese companies were among the world’s leading semiconductor manufacturers. Their strong market position generated trade tensions with the United States, and Japan subsequently agreed to restrictions affecting semiconductor exports.
The experience remains relevant to Japanese policymakers as they attempt to restore the country’s technological competitiveness while managing relations with Washington.
The global chip industry has changed considerably since that period. South Korea and Taiwan have become major semiconductor manufacturing centres, while US companies retain influential positions in chip design, computing architecture and advanced technology development.
China has also invested heavily in developing its semiconductor capabilities, making the industry increasingly important to international competition.
For Japan, rebuilding its position requires sustained investment in research, production facilities, skilled workers and supporting industries. Government assistance can encourage companies to undertake expensive projects, but it cannot guarantee that new facilities will achieve commercial success.
The country must also determine which parts of the semiconductor supply chain it can realistically strengthen and where partnerships with foreign manufacturers provide greater economic value.
Domestic chipmaking remains a priority
Despite its overseas commitments, Japan has continued to support projects intended to expand semiconductor production within its own borders.
One of the most prominent initiatives is Rapidus, which aims to begin mass-producing advanced chips in 2027. The project represents an ambitious attempt to establish domestic capabilities in cutting-edge semiconductor manufacturing.
However, the initiative has attracted scepticism within the industry, reflecting the technical and financial difficulties associated with developing advanced production processes.
Building a semiconductor fabrication plant requires substantial capital, specialised equipment, highly trained personnel and reliable access to materials. Even after construction is completed, manufacturers must refine production processes and achieve sufficient yields before operations become commercially competitive.
The costs and risks are particularly high when a company attempts to enter a segment dominated by established international manufacturers.
Japan is also supporting other businesses and projects. The government has backed AI robotics company Noetra and provided subsidies to Taiwan Semiconductor Manufacturing Company, Micron Technology and Kioxia to establish or expand chipmaking capacity in Japan.
These measures indicate that Tokyo’s approach is not limited to creating a single national champion. Instead, it is attempting to build a broader industrial ecosystem that includes foreign manufacturers, domestic suppliers and companies developing new technologies.
The strategy could help Japanese businesses gain access to manufacturing expertise while supporting local employment and investment. Its effectiveness will depend on how successfully these projects integrate with domestic research, production and supply networks.
Financing presents another challenge
The planned US factories will also require Japan to arrange substantial financing at a time when the country’s public finances face significant pressure.
The Japan Bank for International Cooperation and commercial lenders are expected to provide loans, with guarantees from Nippon Export and Investment Insurance.
However, Japanese banks have been reluctant to participate because of the cost of securing the large quantities of US dollars required for overseas investment. Tokyo has been looking to JPMorgan and other US banks for assistance, according to earlier Reuters reporting.
Financing the projects alongside other announced investments could increase the demands on public institutions and private lenders.
Japan has one of the highest debt-to-GDP ratios among developed economies, while Prime Minister Sanae Takaichi’s plans for fiscal expansion have attracted investor attention.
The government has outlined ambitions for approximately $2.3 trillion in public-private investment through fiscal 2040 across 17 strategic sectors, including semiconductors and artificial intelligence.
That programme reflects the view that government policy must support industries considered essential to long-term economic security. However, competing priorities mean policymakers must weigh the benefits of each project against its financial costs and expected returns.
A semiconductor factory may strengthen strategic supply chains, but the scale of investment makes careful assessment of commercial viability essential.
Can overseas investment strengthen Japan’s supply chain?
Japanese officials have argued that investing in the United States and expanding domestic industry are not necessarily conflicting objectives.
Industry Minister Ryosei Akazawa has maintained that overseas investment can coexist with efforts to stimulate growth at home. He has also described Japan as an important partner for the United States in economic, security and technological matters.
Japanese companies could benefit from the US projects through equipment sales and participation in supply chains. Tokyo Electron, a major manufacturer of semiconductor production equipment, is among the Japanese businesses positioned to benefit from continued investment in chip manufacturing.
GlobalFoundries chief executive Tim Breen has also identified Renesas Electronics as a prospective customer for the facilities.
Such commercial links could create value for Japanese firms even if the factories are located abroad. The benefits, however, would differ from those generated by expanding manufacturing capacity and developing advanced production expertise within Japan.
One possible approach is to integrate chips manufactured in the United States into Japan’s broader industrial supply chain rather than seek to produce every category of semiconductor domestically.
That model could provide greater flexibility and reduce dependence on any single production location. It would also recognise the international character of the semiconductor industry, in which no country operates entirely independently across every stage of production.
Nevertheless, the approach would require Japan to maintain strong domestic capabilities in areas where it has strategic advantages and ensure that overseas partnerships do not undermine its long-term industrial objectives.
Atsushi Osanai, a professor at Waseda University, suggested that Japan may ultimately have to treat the investment as a cost of maintaining its relationship with Washington, regardless of the project’s outcome.
A test of Japan’s technology strategy
The proposed investment highlights a difficult choice facing governments that seek both economic security and stable international trade relations.
For Japan, supporting US semiconductor manufacturing may help protect a vital diplomatic and commercial partnership. It could also generate opportunities for equipment suppliers and businesses participating in international chip supply chains.
At the same time, Tokyo must ensure that its domestic ambitions receive sufficient funding, technical expertise and policy support to become viable.
The success of Japan’s semiconductor revival will not be measured solely by the amount of money committed to overseas projects. Progress will also depend on whether domestic manufacturers can develop competitive products, establish reliable production processes and secure customers in a rapidly changing market.
With artificial intelligence increasing demand for computing power, semiconductors are likely to remain central to economic policy and international competition.
Japan’s challenge is to use its overseas commitments to complement, rather than replace, its domestic industrial strategy. Whether the current approach achieves that balance will become clearer as the US factories advance and Japan’s own semiconductor projects move towards production.
