Tokyo – Japan’s ambitious semiconductor venture Rapidus, backed by roughly $15 billion of public funds, is moving to secure design partners for its upcoming 2‑nanometre (nm) contract chip fab. On Monday the company disclosed collaborations with 17 firms, including U.S. chip‑design software leader Synopsys and India’s Infosys, in an effort to attract the customers needed to fill its high‑tech factory.
Government hopes hinge on customer traction
Prime Minister Sanae Takaichi has positioned the Rapidus project as a cornerstone of Japan’s strategy to rebuild its semiconductor industry and improve supply‑chain resilience amid rising regional tensions. The fab is slated to begin mass production in the second half of the next fiscal year, but the critical question remains: who will actually place orders?
“The biggest question for Rapidus is still who will actually fill the fab,” said Nori Chiou, investment director at White Oak Capital. While the new partnership announcements represent “incremental progress,” Chiou cautioned that they do not yet constitute clear commercial traction.
Intense competition from global leaders
Rapidus will compete directly with established leaders such as Taiwan’s TSMC, South Korea’s Samsung Electronics – which began 2‑nm production last year – and Intel. Akira Minamikawa, an analyst at Omdia, noted that TSMC will continue to dominate the majority of the market, but there remains a niche of customers who cannot secure capacity from TSMC because they are low on its priority list or have smaller orders.
Rapidus CEO Atsuyoshi Koike expressed confidence that market demand is sufficient for an additional leading‑edge manufacturer, stating, “One or two companies are nowhere near enough.” However, some potential customers remain cautious. One executive, who asked to remain anonymous, said, “We’re already having TSMC make our chips, so we can’t switch everything to Rapidus. If it didn’t work out, we couldn’t go back to TSMC, so we have to be cautious.”
Technological hurdles and profitability concerns
Beyond winning orders, Rapidus faces significant technical challenges. The company is working with IBM on pilot operations, but analysts stress that achieving stable, high‑yield production at 2‑nm is extremely difficult. Kazuyoshi Saito of IwaiCosmo Securities warned, “Running a chip fab around the clock, maintaining stable, consistent yields and continuing production in a way that makes the business viable is extremely difficult. Even Samsung has struggled.”
Financial sustainability is also a key issue. Rapidus aims for an initial public offering around the fiscal year ending March 2032, yet a government official highlighted the risk, noting that the Cool Japan Fund, which backs the project, could record investment losses if the fab fails to achieve commercial success.
Potential broader benefits for Japan
Even if customer uptake is gradual, the presence of a domestic leading‑edge fab could bolster Japan’s broader semiconductor ecosystem. Suppliers of materials and equipment may benefit, and the project aligns with other government‑backed initiatives such as Noetra, which is developing foundational AI and robotics models.
Japan’s global semiconductor market share has slipped from about 50 % in the 1980s to less than 10 % today. Rapidus hopes to reverse that trend by providing an alternative source of advanced chips, thereby reducing reliance on foreign suppliers and enhancing national security.
Outlook
Rapidus’ success will depend on converting partnership announcements into actual wafer orders, overcoming the steep technical learning curve of 2‑nm production, and delivering consistent yields that make the operation financially viable. While the government and company remain optimistic, industry observers stress that the next 12‑18 months will be decisive for the fab’s commercial future.
