Singapore-based data centre operator Princeton Digital Group (PDG) has launched its TY1 data centre in Japan, which is said to pack one of the world’s densest amounts of computing power in each rack.
Providing 140kW of capacity per rack, it is aimed at supporting “extreme” AI workloads that require more performance while relying on advanced liquid cooling to power future applications.
Traditional data centres often offer about 10kW of capacity, with some pushing up to 30kW. However, data centres built to support the heavy lifting for AI workloads in the past two years have packed in more computing power in smaller spaces to meet the new requirements.
PDG’s new US$1 billion Tokyo also promises an energy-efficient design, essentially to deliver more capacity without an uncontrolled increase in power consumption or space.
Designed for AI and high-performance computing, the new data centre has a power usage effectiveness (PUE) of under 1.34 and advanced liquid cooling technologies for efficient high-density computing.
Offering a total of 96MW in capacity, PDG’s new facility is located in Saitama City, 35km from central Tokyo.
According to the company, Saitama has scalable resources to overcome restrictions that traditional hubs face. The prefecture has advantages like available land, reliable power supply, and a well-established fibre optic network.
The TY1 facility also promises carrier-neutral connectivity to central and eastern Tokyo, Inzai, and key submarine cable landing stations. Built with robust seismic resilience, the facility is said to exceed Japan’s strict seismic standards.
According to Structure Research, Japan’s data centre market is growing rapidly. Tokyo’s colocation market is expected to double from US$3.7 billion in 2024 to US$ 7.3 billion by 2030.
The demand for hyperscale and AI-related demand is expected to have an annual growth rate of over 20 per cent, growing from 57 per cent to 75 per cent of the overall market by 2030.
“AI has reshaped the data centre landscape, driving demand for advanced infrastructure across Asia,” said Rangu Salgame, chairman, CEO, and co-founder of PDG.
“Our US$1 billion investment in TY1 demonstrates our commitment to Japan as part of our Pan-Asia growth strategy,” he added.
The Tokyo data centre is part of a rapid growth strategy across the region. In September 2024, PDG said it was expanding its data centre capacity in India to a total of 230MW with an investment of US$1 billion in the country. This is part of PDG’s US$5 billion investment for AI-ready data centres in Asia.
The expansion in India includes three new buildings at its MU1 campus in Mumbai, tripling capacity to 150MW and making it one of the city’s largest operational data centre hubs.
