Japan Commits $944M More to Rapidus Chip Venture

Japan is preparing to inject another ¥150 billion ($944 million) into Rapidus Corp., the domestic chip startup positioned as the country's answer to Taiwan Semiconductor Manufacturing Co. in the race for advanced semiconductor production.

The Ministry of Economy, Trade and Industry plans to request the additional funding in its fiscal 2027 budget, according to a person familiar with the deliberations who spoke on condition of anonymity. The Nikkei first reported the budget request, though METI representatives were not immediately available to confirm the details.

An escalating commitment

The new allocation represents a substantial escalation in Japan's bet on Rapidus, which was established to manufacture cutting-edge logic chips domestically. The startup has been working to develop 2-nanometer gate-all-around wafer technology, a next-generation architecture that represents one of the most challenging frontiers in semiconductor manufacturing.

Rapidus faces formidable competition. TSMC dominates the contract chipmaking market with decades of manufacturing expertise, established customer relationships with major tech companies, and proven ability to execute at scale. The Taiwanese giant already produces chips at the 3-nanometer node and is advancing toward 2-nanometer production.

Why it matters

Japan's continued investment in Rapidus reflects a strategic calculation that extends beyond commercial returns. Advanced semiconductor manufacturing has become a national security priority for major economies, particularly as AI applications drive demand for cutting-edge chips. By building domestic foundry capacity, Japan aims to reduce dependence on foreign suppliers and secure access to critical technology for its electronics and automotive industries. The question is whether government funding alone can overcome TSMC's substantial lead in process technology, manufacturing scale, and ecosystem partnerships.

The broader context

The additional funding comes as governments worldwide are pouring resources into domestic chip production. The United States has committed tens of billions through the CHIPS Act, while the European Union has launched similar initiatives. These efforts reflect a fundamental shift in how advanced economies view semiconductor supply chains—less as purely commercial concerns and more as strategic assets requiring state support.

For Rapidus, the challenge extends beyond securing capital. The company must attract top engineering talent, build relationships with equipment suppliers, and convince potential customers to take a chance on an unproven foundry. Success will require not just matching TSMC's process technology, but doing so reliably and at competitive cost—a combination that has eluded many well-funded competitors.

The fiscal 2027 budget request signals that Japan's government remains committed to the Rapidus experiment despite the long odds. Whether that commitment can translate into a viable competitor in the global foundry market remains an open question.
