Japan Bets on Rapidus 2nm: Semiconductor Investment to Reach ¥68 Trillion by 2040
Nashnova编辑部
Japan plans to spend roughly ¥68 trillion on semiconductors by fiscal 2040, with Rapidus's 2nm mass-production target in 2027 as the linchpin — whether that deadline holds will determine if the outlay becomes a strategic turning point or a sunk cost.
How big is ¥68 trillion in context?
Japan has drawn up an investment plan spanning 17 strategic sectors, targeting a combined public-private total of roughly ¥370 trillion by fiscal 2040. AI and semiconductors together account for about ¥101 trillion.
Semiconductors alone come to an estimated ¥68 trillion — over 18% of the 17-sector total. This means → in Tokyo's calculus, chips are the single heaviest bet across every strategic domain.
In plain terms = for every five dollars Japan commits to its future, nearly one goes directly into semiconductors.
Why is Rapidus the centrepiece?
Rapidus is building a fab in Chitose, Hokkaido, aiming to mass-produce 2nm chips by 2027. The 2nm node — among the most advanced process technologies in existence — is currently within reach of only TSMC and Samsung at comparable nodes.
Yamagiwa Daishiro, chair of the ruling LDP's semiconductor-strategy caucus, says Rapidus has stayed exactly on the agreed schedule, calling progress "near-miraculous."
This reflects how Tokyo frames the project: not just one company, but the most important proving ground for Japan's entire semiconductor policy.
Where is the money coming from — and is it enough?
Rapidus's funding so far is overwhelmingly government money; private-sector participation remains limited.
Yamagiwa argues that because semiconductors touch virtually every industry, major corporations are likely to invest in time — and that Rapidus currently has no funding gap.
He also notes that once mass production starts, financing needs will become much clearer, and the government must prepare in advance to ensure sufficient capital is available. This means → the "no shortage" assurance holds today largely because the capital-intensive phase has not yet begun.
Does the government have a safeguard mechanism?
Tokyo has built a milestone-gated funding structure for Rapidus — each phase must hit agreed targets before the next tranche is released.
Yamagiwa calls the 2027 production start "a battle Japan cannot afford to lose" and pledges flexible additional support if needed.
He also vows not to repeat past failures, promising the government will stay involved through the final stage. In plain terms = there is a stage-gate to prevent waste, but also an open door to ensure funding does not cut off at the critical moment.
Who does Japan want as supply-chain partners?
Yamagiwa states plainly that the United States is Japan's first-choice partner for the semiconductor supply chain; Taiwan and Japan play complementary roles.
Even combining Rapidus's and TSMC's projected capacity, he argues, it would still not be enough to meet global demand for the most advanced chips.
This means → Japan does not position Rapidus as a competitor to TSMC but as a supplement to the global shortfall in leading-edge capacity — leaving wide room for deeper Japan-Taiwan cooperation.
Why is the 2027 deadline so critical?
2027 mass production is both the key proof point for Rapidus's business model and the test of whether Tokyo can convert this round of spending into real industrial competitiveness.
In plain terms = if the fab opens on time with viable yields, Japan reclaims a seat at the advanced-chip table; if it slips, the strategic narrative behind ¥68 trillion faces a fundamental challenge.
