Status: Core and Shell Construction Complete (Phase 1); Fit-out Ongoing | Location: Saitama City, Greater Tokyo Area, Japan
The Princeton Digital Group (PDG) TY1 Campus in Saitama City represents a major commitment to digital infrastructure in the Greater Tokyo Area, one of the fastest-growing and most capacity-constrained data center markets in the world. As a colossal Hyperscale Data Center Campus, the project is strategically located just 30km north of central Tokyo in Saitama, offering the stability and scalability needed for land and power while maintaining robust connectivity to the commercial heart of the city.
The campus is planned for a substantial Total IT Load of 96 MW, delivered in two primary phases, with the first phase (a six-story, 48 MW facility) having completed its core and shell construction in Q1 2024. This aggressive timeline reflects the urgent demand from global Cloud Service Providers (CSPs) and large technology firms for capacity in Japan. The overall PDG investment is slated to be in excess of US$1 Billion over the life of the project, underscoring its scale and long-term significance.
The facility is being purpose-built to cater to the infrastructure demands of the world's largest AI and cloud companies. This means the Technical Specifications include advanced cooling systems and design principles optimized for high-density rack deployments—a necessity for modern, power-hungry AI workloads utilizing high-performance GPUs.
In terms of reliability, the design meets the rigorous standards of a hyperscale facility, ensuring high levels of redundancy for power and cooling (Expected N+1 or 2N). Furthermore, sustainability is a core commitment, with the project focusing on energy efficiency and targeting prestigious certifications like LEED certification. The operator mitigated 100% of the Scope 1 and 2 carbon emissions attributable to the construction works, demonstrating a serious focus on its Energy Mix and environmental footprint, a growing expectation in all major global markets like Tokyo.
By leveraging Saitama's stability and robust power grid while providing critical connectivity to Central Tokyo, the PDG TY1 Campus is poised to be a foundational piece of Japan's future digital economy, supporting massive data growth and the acceleration of AI adoption in Asia-Pacific.
