Reported facts

Structured facts sourced from citations already on this record. Each fact traces to a source in the References section below.

Container DC / ~1,000 H200 / 3.5 MVA (primary)
SAKURA internet announced operation of a container-type data center on the Ishikari Data Center grounds starting June 11, 2025, equipped with approximately 1,000 NVIDIA H200 GPUs for Koukaryoku PHY bare metal services. Specs cite construction completed May 2025, power supply capacity about 3.5 MVA, and 40 racks (20 per container), with direct liquid cooling (SAKURA internet, Aug 14 2025)
~1,100 Blackwell GPUs online (primary)
On Feb 25, 2026, SAKURA internet announced it began operating AI infrastructure with approximately 1,100 NVIDIA Blackwell GPUs in the container-type data center at Ishikari, expanding capacity for Koukaryoku generative AI cloud, sakuraONE managed supercomputer, and sakura AI business platform (SAKURA internet, Feb 25 2026)
Prior H100 buildout (primary)
SAKURA's Feb 2026 Blackwell release links its Aug 1, 2024 announcement that it completed preparation of 2,000 NVIDIA H100 Tensor Core GPUs as prior Ishikari / Koukaryoku capacity context (SAKURA internet, Feb 25 2026; prior release cited: SAKURA H100, Aug 1 2024)
DLC / rack density note (primary)
The H200 container announcement says direct liquid cooling is expected to cut cooling power versus air-only, and that improved cooling allows up to five GPU servers per rack versus two in the company's conventional configuration (company-stated performance, configuration-dependent) (SAKURA internet, Aug 14 2025)
Campus scale / 5-building masterplan (primary)
SAKURA internet's Ishikari Data Center location page describes a large suburban campus on a site about 1.1 times the area of Tokyo Dome, with a modular multi-building plan ultimately targeting five buildings and about 6,800 racks (about 1,280 racks per building at max). Buildings 1 and 2 completed in 2011 and Building 3 in 2016 (SAKURA Ishikari DC)
Free-air cooling / 66 kV dual feed (primary)
The Ishikari campus page states Buildings 1-2 use direct free-air cooling and Building 3 uses indirect free-air (refrigerant loop cooled by outside air), plus 66 kV dual-feed utility intake, diesel generators with about 48 hours unrefueled runtime, and nitrogen gas fire suppression. Cooling design is framed as leveraging Hokkaido's cool climate for energy efficiency (SAKURA Ishikari DC)
Container build speed vs Building 3 (primary)
SAKURA's Aug 14, 2025 H200 container release contrasts Building 3's roughly three years and three months from planning to 2016 completion with the container-type data center's roughly one and a half years from planning to May 2025 completion, citing generative AI demand as the reason for the faster modular path (SAKURA internet, Aug 14 2025)
