Japan Puts Another $944 Million Behind Its Long-Shot Chip Bet

Japan once made half the world's chips. Then it didn't. The effort to reverse that decline now runs largely through a single company, Rapidus, and this week Tokyo signalled it is not done writing cheques. The government intends to allocate a further 150 billion yen, about $944 million, to the venture, with the Ministry of Economy, Trade and Industry set to fold the request into its fiscal 2027 budget.

Rapidus is not an ordinary startup. It was assembled with state backing and the participation of major Japanese firms, with one specific goal: to begin producing advanced 2-nanometre logic chips inside Japan by 2027. That is the most cutting-edge class of processor in volume production, the kind that powers the AI accelerators and data centres now soaking up global capital. Today only a small handful of manufacturers can make them at all.

A national-security argument, not just an industrial one

The framing from Tokyo is telling. Officials describe domestic chipmaking less as an economic opportunity than as a matter of security and technological independence, given how central semiconductors have become to AI, robotics and defence. When the supply of the most advanced chips runs through a couple of companies in Taiwan and South Korea, a country without its own capacity is exposed in a way that money alone cannot quickly fix.

That anxiety is not confined to Japan. It sits behind Samsung's move to raise foundry prices as demand outstrips supply, and behind the scramble for novel designs like IBM's dual-architecture 2-nanometre processor. Everyone wants a seat at the leading edge, and almost no one can build one from scratch.

The size of the gamble

The honest word for Rapidus is long shot. It is attempting to leap to 2-nanometre production without the decades of incremental manufacturing experience that TSMC accumulated on the way there, and it is doing so as a relative newcomer. Success would give Japan something very few nations have. Failure would burn through billions in public money with little to show for it.

Tokyo appears to have decided the risk of standing still is worse. Another $944 million does not guarantee Rapidus reaches its 2027 target. It does show that Japan, having watched its lead evaporate once, is unwilling to sit out the race for the silicon that AI now runs on.
