What is established
Partially operational. 2,000 accelerators (NVIDIA H100 (B200/Blackwell expansion underway)); expected Jan 2027; owned or developed by Sakura Internet.
What is not disclosed
Capacity, project capex, named tenant, power source, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
~2,000 H100s operational at Ishikari (NVIDIA PR: expanding 'from 2,000 to nearly 4,000 NVIDIA Hopper GPUs'); HGX B200 planned toward ~10,800 total GPUs. Company added ~1,100 Blackwell GPUs in a container DC at Ishikari announced 2026-02-24 (company announcement). Backed by ~JPY50.1bn METI subsidy for national GenAI compute; site targeted fully renewable by 2027. gpuCount reflects confirmed installed H100 base, not targets.
Physical work is under way and the evidence includes a primary source.
