Princeton Digital Group opens US$1 B data centre in Japan

Princeton Digital Group (PDG), the data centre provider, has launched its TY1 campus in Saitama City, Japan. The US$1 billion facility has an IT capacity of 96 MW, and is one of Japan’s largest and most advanced data centres, PDG said. 

TY1 is purpose-built for high-performance AI computing. Located approximately 35 km from central Tokyo, the facility delivers 140 kW per rack of high-density capacity to support AI workloads. TY1 has a PUE of < 1.34 and is equipped with advanced liquid cooling technologies for efficient high-density computing.

“AI has reshaped the data centre landscape, driving demand for advanced infrastructure across Asia. Our US$1 billion investment in TY1 demonstrates our commitment to Japan as part of our Pan-Asia growth strategy,” said Rangu Salgame, Chairman, CEO and Co-Founder of PDG. 

Tokyo's colocation market expected to double from US$3.7 billion in 2024 to US$7.3 billion by 2030, according to Structure Research. Hyperscale and AI-related demand is projected to grow from 57% of the overall market to approximately 75% by 2030, with an annual growth rate of over 20%. These deployments require access to scalable land, reliable power, and robust connectivity, delivered by credible data centre operators. 

As existing facilities in central and eastern Tokyo face significant constraints in these areas, Saitama Prefecture is well-positioned due to the availability of power and land, with strong connectivity to existing clusters. In addition to the advantage of being located in Saitama, PDG’s TY1 also benefits from the company’s successful track record across the region.

Salgame added: "Saitama offers scalable resources that address constraints faced in traditional hubs. With industry-leading power density and sustainability, TY1 further strengthens PDG's position as the partner of choice for hyperscalers deploying AI workloads in the region."

PDG's investment leverages Saitama Prefecture's unique advantages, including available land, stable power resources, and a well-established fibre optic network. The facility provides carrier-neutral connectivity to central and eastern Tokyo, Inzai, and key submarine cable landing stations, and has been designed with seismic resilience that exceeds Japan's stringent earthquake standards.
