Ubitus to build AI data center in Japan using NVIDIA Blackwell chips

Ubitus K.K., a cloud streaming and AI solutions provider, is partnering with Maizuru City, Kyoto Prefecture, to build an AI GPU data center powered by NVIDIA Blackwell GPUs. The land signing ceremony and press conference took place on January 29, 2026. The site spans 2.3 hectares (23,000 m²), offers stable power, and has low disaster risk. Ubitus will deploy its NeoCloud architecture to support high-density GPU racks, hierarchical scheduling, and dynamic resource allocation for low-latency training and inference of generative AI and large language models (LLMs).

Construction begins in 2026 with phased delivery: Phase 1 will complete core facilities; Phase 2 will expand capacity, targeting major completion in 2027. The project is backed by a Ministry of Economy, Trade and Industry (METI) large-scale investment grant and a JPY 17 billion ($113 million) commitment. It aims to accelerate AI applications in tourism, healthcare, education, and enterprise. The facility will support Ubitus' 405-billion-parameter GENIAC LLM and Maizuru's "Chokimaru" tourism AI guide. NVIDIA is supporting the project through its Connect program.

Why It Matters

• Enables enterprises and ML teams to run genAI workloads closer to users and data, reducing latency and network egress.
• NVIDIA Blackwell GPUs deliver efficiency and throughput for large-scale model training and inference, easing local compute shortages.
• METI funding and the regional site strengthen sovereign AI capacity and support local skilled-job creation during construction and operation.
• Phased rollout and NeoCloud's hierarchical scheduling provide early access to next-gen GPUs with predictable resource allocation for DevOps and MLOps teams.
