Cloud streaming and AI solutions provider Ubitus K.K.,has announced plans to construct an AI data center in Maizuru City, Kyoto Prefecture, Japan on a site spanning approximately 2.3 hectares (around 23,000 square meters). The AI Data Center in Maizuru City marks the company’s transition into the physical construction phase of its initiative to build an AI GPU center in Japan.
In a press release, Ubitus revealed that it chose the site because it offers favorable land conditions and infrastructure readiness, with proximity to port and logistics facilities, making it well suited for the development of high-density, high-reliability AI computing infrastructure.
Ubitus says that the Maizuru City AI Data Center will “fully adopt NVIDIA’s latest-generation Blackwell GPU architecture, specifically designed to support high-efficiency training and inference for generative AI and large language models.” It further said that the platform supports high-density GPU deployment and sustained large-scale workloads, positioning the facility among the few in Japan capable of meeting next-generation AI compute demands.
Moreover, the overall computing architecture will be centered on NeoCloud, which features hierarchical scheduling, distributed computing, and flexible resource management. “This design enables dynamic allocation of GPU resources based on regional, industry-specific, and project-level AI needs—enhancing compute efficiency while reducing latency and avoiding the bottlenecks associated with centralized architectures,” said Ubitus.
In terms of development approach, Ubitus said that the Maizuru City AI Data Center will adopt a phased construction strategy. While Phase 1 will focus on building the data center and progressively deploying core facilities and operational capabilities, Phase 2 will expand capacity in response to the evolving demands of generative AI and large language models, supporting medium- to long-term growth in compute requirements.
“This flexible expansion plan ensures that the AI Data Center can scale steadily in line with industry demand while maintaining operational efficiency and long-term sustainability,” said Ubitus.
Ubitus says that this land agreement represents the “first major milestone” following its selection for a large-scale investment grant from Japan’s Ministry of Economy, Trade and Industry (METI), under which the company committed to building AI GPU infrastructure. “It also symbolizes a significant step forward in collaboration between the central government, local governments, and the private sector to advance AI infrastructure development in Japan,” said Ubitus.
Construction is expected to begin in 2026, with major development targeted for completion within 2027.
