Tokyo, Japan - February 9, 2026 - Digital Realty said its NRT14 data center in the Greater Tokyo area has earned NVIDIA DGX-Ready Data Center certification, marking a significant milestone for AI-ready infrastructure in Japan as demand accelerates for high-density computing environments.
The certification, issued under NVIDIA’s DGX-Ready Data Center program, confirms that the NRT14 facility meets strict technical requirements to support next-generation NVIDIA AI platforms, including DGX GB200 systems and Grace Blackwell-based architectures. These systems are designed for large-scale AI training and inference workloads that require substantially higher power density and advanced cooling compared with traditional data center deployments.
According to NVIDIA’s certification criteria, DGX-Ready facilities must be capable of supporting rack power densities of 100 kilowatts or more, along with resilient power distribution and liquid-cooling infrastructure. Digital Realty said NRT14 was purpose-built to meet these requirements, positioning it among the first facilities in Japan designed specifically for liquid-cooled, GPU-dense AI workloads.
The NRT14 data center is being developed by MC Digital Realty, a 50-50 joint venture between Digital Realty (NYSE: DLR) and Mitsubishi Corporation. The project forms part of Digital Realty’s broader expansion strategy in Asia-Pacific, where enterprises and cloud providers are increasingly seeking AI-capable colocation and interconnection infrastructure.
“Achieving NVIDIA DGX-Ready certification underscores our ability to deliver the infrastructure required for the next generation of AI computing,” said Chris Sharp, Chief Technology Officer at Digital Realty. “This milestone reflects years of close collaboration with NVIDIA and demonstrates our commitment to helping customers operationalize AI at scale.”
NVIDIA has said that liquid-cooled Grace Blackwell architectures can deliver up to 25 times greater energy efficiency compared with traditional air-cooled systems, a factor that is becoming increasingly important as AI workloads push data center power and thermal limits. Industry analysts note that certification programs such as DGX-Ready are emerging as key indicators of a facility’s ability to support future AI deployments without compromising reliability or efficiency.
The Tokyo certification builds on Digital Realty’s global partnership with NVIDIA, which includes the NVIDIA AI Factory Research Center at Digital Realty’s Northern Virginia campus. Digital Realty now operates DGX-Ready certified facilities in more than 20 countries, providing multinational customers with a consistent platform for deploying AI infrastructure across regions.
Digital Realty said the NRT14 facility will play a central role in supporting Japan’s growing AI ecosystem, offering enterprises, cloud providers, and research institutions access to infrastructure designed to handle the most compute-intensive workloads. As AI adoption accelerates across industries, the company expects demand for certified, high-density data center capacity in the region to continue rising.
