A 'world's first' that won't switch on until 2028
The headline number is 27,500 Nvidia Rubin GPUs and 13,750 Vera CPUs, packed into a 140-megawatt facility [2]that Nvidia and Noetra are calling the world's first national AI infrastructure [1]. But the fine print undercuts the urgency of the framing: construction is not scheduled to begin until April 2027, with operations targeted for June 2028 [3]. That means nearly two years separate Tokyo's July 2026 press conference from the first watt of compute actually reaching Japanese researchers and manufacturers. The gap matters because the funding structure behind it is real and substantial - up to 1 trillion yen (about $6.2 billion) over five years, with 387.3 billion yen already earmarked for fiscal 2026 [3]- so the government is paying now for capacity that arrives later. The announcement functions less as a delivery date and more as a coordination signal: a public commitment binding roughly 44 companies, a state ministry, and a single foreign chip supplier to a multi-year build before a single rack is powered on.
