Rapidus explained: Japan's state backed 2nm chip project and its money

Rapidus is a Japanese company, founded in August 2022 and backed by the government and private investors, that plans to mass produce advanced 2 nanometre logic chips in Hokkaido from 2027. Reported public support runs to roughly 2.4 trillion yen. It has a pilot line running, but no confirmed mass production yet.

This post explains the project in plain terms: what the company makes, how it is paid for, what has been announced and when, and which claims are still unproven. Every figure is labelled by who reported it and when. Where sources give different totals, both are shown. Nothing here is investment advice, and Rapidus is a private company, so its numbers are not audited public filings.

• Founding capital: 7.3 billion yen (as reported by Pulse 2.0 and, for eight companies, by Digitimes, November 2024).
• Early 2026 round: 267.6 billion yen, made of 100 billion yen from a government agency and 167.6 billion yen from 32 private companies (Rapidus announcement, reported by Pulse 2.0, 27 February 2026).
• Latest government equity step: 150 billion yen from the Information-technology Promotion Agency, completed 5 June 2026 (Rapidus, 5 June 2026).
• Total government equity so far: 250 billion yen (Argus Media, 5 June 2026).
• Subsidies planned: 631.5 billion yen in fiscal 2026 to 2027 and about 300 billion yen in fiscal 2027 to 2028 (Argus Media, 5 June 2026).
• Total government backing: about 2.4 trillion yen after an extra 631.5 billion yen approved on 11 April 2026 (TrendForce, 13 April 2026, citing Yomiuri Shimbun).
• Earlier subsidies: 920 billion yen through three budget amendments from 2021 to 2023 (Digitimes, 29 November 2024).
• Pilot line began operating: April 2025 (Rapidus website, October 2026).
• First working 2nm gate all around transistors: 18 July 2025 (Rapidus website, October 2026).
• Mass production target: second half of fiscal 2027 (Rapidus, 11 April 2026). Argus describes it as fiscal 2027 to 2028.

Japan's fiscal year runs from April to March, so "fiscal 2027" means April 2027 to March 2028.

What Rapidus is trying to build

A logic chip is the kind of chip that does computing, as opposed to memory chips that store data. Processors in phones, servers and AI accelerators are logic chips. The "2 nanometre" label describes a manufacturing generation, a way of naming successive processes. It is no longer a literal measurement of any single feature on the chip, so treat it as a generation marker rather than a ruler.

What sets this generation apart is the transistor design. Rapidus describes its process as 2nm GAA, which stands for gate all around. In older designs the control electrode touched the current channel on a few sides. In a gate all around design it wraps the channel, which gives tighter control and helps cut power leakage. Rapidus says it achieved the first successful operation of 2nm GAA transistors on its pilot line in Chitose, Hokkaido, on 18 July 2025. That is the company's own statement of a laboratory scale milestone. It tells you the process can make working transistors, not that it can make millions of good chips cheaply.

The gap between those two things is the whole story of a new factory. A pilot line proves the recipe. Mass production proves yield, the share of chips on a wafer that work. Yield is hard to reach, and it decides whether a foundry, a company that makes chips designed by others, can make money. Rapidus has not published yield figures, and this post does not guess at them.

The company calls its manufacturing site the Innovative Integration for Manufacturing hub, or IIM, with the first building known as IIM-1. It sits in Chitose, Hokkaido. The company also describes a business model it calls RUMS, for Rapid and Unified Manufacturing Service, built around short turnaround times from design to finished chips. It pairs that with AI assisted design tools it calls Raads.

Why Japan wants this

Japan's government sees a gap at the leading edge of chip making. Digitimes, reporting in February 2024, said Japan could then produce logic chips only down to 40 nanometres, and otherwise imported advanced chips or had them made abroad. The reporting treats that as a security concern as well as an industry one.

Argus Media notes that Japan designated semiconductors a critical material in 2022 on economic security grounds. In a statement quoted by Argus on 5 June 2026, trade minister Ryosei Akazawa called the Rapidus project "a national undertaking that must succeed for the benefit of Japan." That is a political commitment and a strong one, so it helps to see how much money sits behind it.

Japan's cabinet also treats chips as part of its AI plan. The second AI Basic Plan, adopted on 14 July 2026, says Japan intends to remain "indispensable" in semiconductors, data centres and equipment. For the plan itself, see Japan's second AI Basic Plan explained.

How the project is funded

There are three kinds of money in the Rapidus story, and mixing them up is the most common error in coverage.

The first is subsidies. These are grants paid through a government development agency called NEDO, the New Energy and Industrial Technology Development Organization. Rapidus says it has received NEDO subsidies since fiscal 2022 for two projects: 2nm generation integration and short turnaround manufacturing built on Japan and United States collaboration, and chiplet and packaging technology for the 2nm generation. Digitimes reported in November 2024 that Rapidus had received a total of 920 billion yen in subsidies across three budget amendments between 2021 and 2023. On 11 April 2026, Rapidus said NEDO approved its fiscal 2026 plan and budget for the 2nm projects.

The second is government equity. This means the state buys shares, which is different from a grant because the state becomes an owner. The Information-technology Promotion Agency, known as IPA, is an independent agency under the trade ministry, METI. Rapidus said that IPA put in 100 billion yen as part of a 267.6 billion yen round announced at the end of February 2026, then a further 150 billion yen completed on 5 June 2026. Argus puts total government equity at 250 billion yen and says the new funds support equipment for 2nm mass production and research on 1.4nm technology.

The third is private money. In the early 2026 round, Rapidus said 32 companies contributed 167.6 billion yen. Named investors include Canon, the Development Bank of Japan, Fujitsu, NTT, SoftBank and Sony Group. After the June 2026 step, Rapidus reported capital of 424.95 billion yen.

What the total really is

The most quoted figure is about 2.4 trillion yen in total government backing. TrendForce, citing the newspaper Yomiuri Shimbun on 13 April 2026, said METI approved an extra 631.5 billion yen on 11 April and that this brought backing to about 2.4 trillion yen. Argus, on 5 June 2026, describes the same 631.5 billion yen as a subsidy planned for fiscal 2026 to 2027, followed by about 300 billion yen in fiscal 2027 to 2028.

Those two reports are consistent, but they describe a schedule of payments, not a lump sum already received. Neither Rapidus nor METI has published a single official cumulative figure on the pages cited here, so the 2.4 trillion yen number is a newspaper figure relayed by a trade publication. Check the METI budget documents before relying on it.

For scale, Digitimes in November 2024 reported an estimate that the pilot phase would cost about 2 trillion yen, with another 1 trillion yen needed, and that mass production would need a further 3 trillion yen. Those were reported estimates from that time. Argus now says Rapidus is expected to need about 1 trillion yen of private equity and more than 2 trillion yen in private financing. The two sets of numbers use different framings and should not be added together.

A timeline of what has been announced

The following dates come from Rapidus statements unless another source is named.

• 10 August 2022: Rapidus is founded.
• April 2025: the pilot line starts operating at IIM-1.
• 18 July 2025: first working 2nm GAA transistors.
• 3 September to 2 October 2025: METI runs a public call for operators able to produce semiconductors stably. Pulse 2.0 reports that Rapidus was selected as the operator on 21 November 2025.
• 27 February 2026: the 267.6 billion yen round is announced.
• 11 April 2026: the Analysis Center and Rapidus Chiplet Solutions open, with the trade minister, the Hokkaido governor and the Chitose mayor attending. NEDO approves the fiscal 2026 budget the same day.
• 5 June 2026: the 150 billion yen IPA step completes.
• 15 and 16 June 2026: Rapidus signs memoranda of understanding with the UK Semiconductor Centre and with Fondazione Chips-IT in Italy, under government to government frameworks.
• 9 July 2026: a statement about an estimated wafer price, covered below.
• 16 and 17 July 2026: a collaboration with Cadence on AI agent assisted chip design is announced.
• 5 October 2026: the Rapidus CORE ecosystem is launched.

The Analysis Center sits next to IIM-1 and does physical, chemical and electrical testing of chips, including reliability testing. The chiplet facility sits at a Seiko Epson plant in Chitose and works on advanced packaging. Packaging matters because many modern AI processors combine several smaller chips, called chiplets, on one carrier. Rapidus says its chiplet site has produced a prototype 600 millimetre square panel carrying a redistribution layer, which is the wiring that links those chips. It says the site is now beginning full scale operations.

Who might buy the chips

A foundry needs customers before it needs a ribbon cutting. Public information here is thin and mostly reported rather than announced.

TrendForce, citing Nikkei, reported that Canon placed an order for image processing chips for digital cameras. Citing the Yomiuri Shimbun, TrendForce also reported that Fujitsu and IBM Japan plan to adopt 2nm class chips and are expected to have them made by Rapidus, and that METI plans R&D support of up to 58.5 billion yen for Fujitsu and up to 17.5 billion yen for IBM Japan under a NEDO programme. TrendForce, citing another outlet, added that Fujitsu plans to have Rapidus make AI processors on a reportedly more advanced 1.4nm process. These are newspaper reports. They are not signed supply contracts that Rapidus has published.

On 5 October 2026 Rapidus announced Rapidus CORE, short for Collaborative Open Rapid Ecosystem, and a first group called Design Solution Associates. It lists 17 companies, including Cadence Design Systems, Synopsys, Dai Nippon Printing, TOPPAN, Infosys, Wipro, HCL Technologies and Toshiba Information Systems. Their role is to bridge customers and Rapidus by supplying design resources and expertise. Rapidus says CORE will later expand to design software, ready made circuit blocks and other categories.

The wafer price question

On 9 July 2026, Rapidus published a short statement after media reported an estimated price per wafer, based on remarks by chief executive Atsuyoshi Koike at a seminar. The company said prices vary a great deal with the specifications of the products design companies order, that exchange rates also move them, and that the reported figure "does not necessarily reflect the actual selling price." The statement gives no number, so this post does not repeat any. If you see a wafer price quoted for Rapidus, treat it as an unofficial estimate.

How it compares with TSMC in Kumamoto

Japan has also backed a foreign foundry on its soil. Digitimes reported in February 2024 that the government planned up to 730 billion yen for a second Kumamoto fab run by JASM, a venture led by TSMC, on top of 476 billion yen for the first, bringing total subsidies to about 1.2 trillion yen. The Taipei Times, in March 2024, gave the second fab grant as 732 billion yen and said the first Kumamoto plant opened on 24 February 2024.

Those two 2024 reports disagree on when the second fab starts: Digitimes said construction was scheduled for late 2024, while the Taipei Times said the end of 2025, with mass production at the end of 2027. Neither JASM nor TSMC has published an updated schedule in the sources cited here, so its current status is not stated in this post. The point of comparing them is the model. In Kumamoto the state subsidises a foreign operator that already knows how to run a leading fab. With Rapidus the state is funding a new Japanese operator, which is a bigger bet.

What is firm and what is uncertain

Firm, because Rapidus or an official source states it: the company's founding date, its capital of 424.95 billion yen as of 5 June 2026, the 100 billion yen and 150 billion yen government equity steps, the 18 July 2025 first transistor milestone, the April 2026 facility openings, the 17 company design group and the stated 2027 target.

Reported by media but not confirmed in an official statement: the 2.4 trillion yen total, the Canon and Fujitsu orders, the support for Fujitsu and IBM Japan, and the private funding gap.

Uncertain: yield, cost per wafer, customer volumes, whether the second half of fiscal 2027 date holds, and how much private money will arrive. A pilot line does not guarantee a factory.

What to watch next

• Whether Rapidus confirms named customers with volumes and not only intentions.
• Any statement on yield or on the first mass production wafers in fiscal 2027.
• How much of the 1 trillion yen equity and 2 trillion yen financing target is raised, and from whom.
• Further METI budget documents that show actual subsidy paid against plan.
• Progress at the chiplet site, since AI chips depend on packaging.
• Whether the follow on 1.4nm research funded in 2026 gets its own timeline.
