METI grant / JPY 17B Blackwell NeoCloud (primary)
On Dec 18, 2025, Ubitus announced selection for METI's Large-Scale Growth Investment Grant for Medium-Sized and Small Enterprises for its 'Regional Distributed GPU Infrastructure Development for the Generative AI Era' project, with total investment of JPY 17 billion dedicated to expanding cloud infrastructure powered by NVIDIA Blackwell GPUs and NeoCloud (Ubitus, Dec 18 2025)
Maizuru land agreement / 2.3 ha (primary)
On Jan 29, 2026, Ubitus announced a land signing ceremony with Maizuru City, Kyoto Prefecture, for an AI data center on approximately 2.3 hectares (about 23,000 square meters). The company said construction was expected to begin in 2026 with major development targeted for completion within 2027, in phased buildout supporting generative AI and LLM demand (Ubitus, Jan 29 2026)
NVIDIA Blackwell x NeoCloud design (primary)
Ubitus states the Maizuru AI Data Center will fully adopt NVIDIA's Blackwell GPU architecture for high-efficiency training and inference, with overall computing architecture centered on NeoCloud hierarchical scheduling, distributed computing, and flexible resource management. No published MW capacity figure is stated in these company releases (Ubitus, Jan 29 2026; Ubitus, Dec 18 2025)
Groundbreaking Sep 4 2026 (primary)
On Sept 9, 2026, Ubitus announced it held a groundbreaking ceremony for the Maizuru AI Data Center at 10:00 a.m. on Sept 4, 2026, marking transition from planning into full-scale construction after the January land agreement. The release reiterates the ~2.3 hectare phased campus with NVIDIA Blackwell GPUs and NeoCloud (Ubitus, Sept 9 2026)
Phased build / port-logistics site (primary)
Ubitus's Jan 29, 2026 land release says Maizuru will use phased construction: Phase 1 builds the data center and core operations, Phase 2 expands capacity for generative AI and LLM demand, with construction expected to begin in 2026 and major development targeted for completion within 2027. The site is described as near port and logistics facilities with favorable land and infrastructure readiness. No published MW capacity figure is stated (Ubitus, Jan 29 2026)
Site selection / stable power framing (primary)
Ubitus lists Maizuru site-selection strengths as stable power supply conditions, disaster-risk-aware siting, well-developed port and logistics infrastructure, and coordinated government-private collaboration, framing the city as balancing stability, scalability, and long-term operational requirements for high-density AI compute (Ubitus, Jan 29 2026)
GENIAC 405B / Chokimaru Maizuru AI (primary)
Ubitus's METI grant release and land announcement place Maizuru within a longer Japan AI path: 2024 selection for METI's GENIAC program to develop a 405-billion-parameter East Asia LLM (Japanese, Traditional Chinese, English), and 2025 launch of a tourism/cultural AI language model with Maizuru virtual guide 'Chokimaru' offering real-time multilingual Q&A. The 2025 METI Large-Scale Growth Investment grant then funds multi-region Blackwell NeoCloud GPU infrastructure (Ubitus, Dec 18 2025; Ubitus, Jan 29 2026)
