Japan and Nvidia to Build 140MW National AI Factory With 27,500 Rubin GPUs

The state-backed facility will train open multimodal models for robotics and industrial automation using staged government grants.

Overview

  • Nvidia and Noetra Corp. announced the 140-megawatt design and exact hardware counts on July 16, with 27,500 Rubin GPUs arranged in 382 NVL72 racks and 13,750 Vera CPUs.
  • Noetra is a consortium led by SoftBank, Sony, NEC and Honda that won the FRONTia public tender to operate the program and receive initial government support.
  • The Japanese government approved ¥387.3 billion in first-year funding and has pledged up to ¥1 trillion over five years subject to annual stage-gate reviews, so the full disbursement is conditional.
  • Nvidia says Rubin GPUs and Vera CPUs are in production and that Rubin-based systems will be available to partners in the second half of 2026, but an exact construction and operational timeline for the factory has not been formally confirmed and some third-party reports of a 2028 start are disputed.
  • The project targets open foundation models for robotics, digital twins, and factory automation, a move that will drive demand for chip packaging, high-bandwidth memory, networking and power infrastructure and could accelerate automation in labor-short sectors across Japan.
