Japan just threw another $4 billion at its biggest semiconductor bet in decades. The country’s Ministry of Economy, Trade and Industry approved 631.5 billion yen in fresh funding for Rapidus Corp. on Saturday. That brings total government backing for the startup chipmaker to roughly $16.3 billion.
Rapidus is trying to do something that sounds almost reckless on paper. A company founded in 2022 with zero advanced manufacturing experience wants to mass-produce 2-nanometer chips by fiscal year 2027. That’s the same cutting-edge node that TSMC, the world’s dominant chipmaker, only began volume production on last year.
An external technical committee inspected the Rapidus foundry in Chitose, Hokkaido before the latest funding was approved. The committee signed off on the company’s technological progress. Industry Minister Ryosei Akazawa visited the site on Saturday and reaffirmed the 2027 production target.
Why Japan is betting big on Rapidus 2nm chips
The money isn’t charity. It’s national security math. TSMC controls around 90% of the world’s leading-edge chip production. Almost all of it sits in Taiwan. One disruption to that island’s supply chain and the global AI industry hits a wall. Every GPU, every cloud inference call, every frontier AI model runs on chips fabbed at those nodes. Japan wants an alternative. So does everyone else.
The US has the CHIPS Act. Europe has its own subsidy programs. South Korea backs Samsung. Japan has Rapidus.
The latest $4 billion goes toward Rapidus’s work with Fujitsu, its first commercial anchor client. Fujitsu is developing AI and high-performance computing chips that will be among the first manufactured at the Hokkaido facility. Toyota, Sony, NEC, SoftBank, Denso, Kioxia, NTT, and MUFG are also backing the project as corporate investors.
In February, Rapidus raised about 160 billion yen from private companies. The government holds an 11.5% stake and a golden share giving it veto power over key management decisions. Prime Minister Sanae Takaichi has stressed that semiconductor self-sufficiency is a matter of national security. The recent flare-up in tensions between Japan and China has only sharpened that urgency.
NEDO, the ministry’s subordinate research body, is also now supporting semiconductor design projects involving Fujitsu and IBM Japan. That signals Japan isn’t focused on manufacturing alone. It wants to rebuild a full chip ecosystem, from design to fabrication.
How Rapidus stacks up against TSMC, Samsung and Intel
On paper, Rapidus has made surprising progress. Its 2nm process, called 2HP, has hit a logic density of 237.31 million transistors per square millimeter. TSMC’s N2 node sits at 236.17 million. Intel’s 18A process trails at 184.21 million. Those are early-stage specs, not production-proven numbers. But they got people’s attention.
Rapidus launched its 2nm pilot line in April 2025 using ASML’s most advanced High-NA EUV lithography machines. It taped out a gate-all-around test chip that met key electrical benchmarks. The company is now transitioning from pilot to its IIM-1 mass production facility in Chitose. Advanced packaging trial production started this month.
Rapidus wants to hit 25,000 wafer starts per month once mass production kicks off. TSMC is pushing its own 2nm lines toward 100,000. Big gap. But Rapidus isn’t chasing TSMC on volume. The whole model is different. Faster turnaround. Smaller batches. Custom work for clients iterating on chip designs quickly. Think of it as a boutique foundry, not a factory floor.
There’s already a second fab in the pipeline too. Rapidus says it will build another facility in Hokkaido, this one aimed at 1.4nm chips. Construction could start in fiscal 2027. Production is penciled in for 2029. The company is working with Imec, the Belgian semiconductor research center, on the underlying tech for that node.
None of this is guaranteed. Analysts have called the timeline aggressive. TSMC took seven years to go from research to volume production on its 3nm node. Rapidus is trying to compress a similar leap into roughly five years. The technology is one challenge. Getting yields high enough to make production commercially viable is another. Attracting customers beyond Fujitsu will be the real test.
But Japan’s government has made clear it’s willing to keep writing checks. Rapidus is targeting an IPO around fiscal 2031 and plans to secure about 3 trillion yen in private financing, partly with government loan guarantees. If it hits its milestones, some analysts estimate Japan could capture up to 20% of the global market for leading-edge logic chips by the early 2030s.
For now, the race is still TSMC’s to lose. But Japan is no longer watching from the sidelines.
