NextFin News - In a move that signals the accelerating integration of high-performance computing into the Asia-Pacific infrastructure landscape, Digital Realty announced on February 9, 2026, that its NRT14 data centre in the Greater Tokyo area has officially earned the NVIDIA DGX-Ready Data Center certification. This milestone, achieved through MC Digital Realty—a 50/50 joint venture between Digital Realty and Mitsubishi Corporation—positions the facility as one of the first in Japan capable of hosting the NVIDIA GB200 NVL72 systems. According to Bernama, the certification validates the facility's readiness to handle the extreme power and thermal requirements of the Grace Blackwell architecture, specifically supporting high-density AI workloads that reach or exceed 100 kW per rack.
The achievement of this certification is not merely a technical badge; it is a response to the shifting physics of modern computing. As U.S. President Trump’s administration continues to emphasize American technological leadership and the expansion of AI-ready infrastructure globally, the NRT14 facility serves as a critical node in the "AI Factory" model. By implementing advanced liquid cooling technologies, the Tokyo-based centre addresses the fundamental limitation of traditional data centres: the inability of air-cooling systems to dissipate the heat generated by next-generation GPUs. According to NVIDIA, liquid-cooled Blackwell architectures can deliver up to 25 times greater energy efficiency than traditional air-cooled systems, a metric that is becoming the primary driver for enterprise colocation decisions in 2026.
The strategic importance of NRT14 is underscored by the broader economic context of the Asia-Pacific region. As Nah, Managing Director and Head of Asia Pacific at Digital Realty, noted, the region is emerging as an epicenter for digital transformation. The certification of NRT14 follows the 2023 certification of the KIX13 facility in Osaka, indicating a concentrated effort by Digital Realty to build a high-density corridor in Japan. This trend is driven by the concept of "Sovereign AI," where nations seek to host sensitive AI training and inference workloads within their own borders to ensure data security and latency optimization. For Japanese enterprises, the availability of a DGX-Ready facility means faster time-to-insight and reduced operational costs, as they no longer need to rely on overseas cloud clusters for their most demanding analytics.
From a technical standpoint, the transition to 100 kW per rack represents a quantum leap in data centre design. Standard enterprise data centres typically operate at 5 kW to 15 kW per rack. Moving to 100 kW requires a complete overhaul of power distribution and thermal management. The NRT14 facility utilizes liquid-to-chip cooling, which brings the coolant directly to the heat source, allowing for the dense packing of NVIDIA Blackwell GPUs. This density is essential for the low-latency communication required between GPUs in a cluster, which is the backbone of large language model (LLM) training. Sharp, Chief Technology Officer at Digital Realty, emphasized that this milestone is the culmination of years of collaboration with NVIDIA to turn AI ambition into operational reality.
Looking forward, the certification of NRT14 is likely to trigger a "certification race" among global data centre providers. As the NVIDIA Blackwell architecture becomes the industry standard for generative AI, facilities that lack DGX-Ready status risk becoming legacy assets, relegated to hosting lower-value general-purpose cloud workloads. We expect to see a surge in retrofitting projects across the Tokyo and Osaka metros as competitors attempt to match the liquid-cooling capabilities of MC Digital Realty. Furthermore, the involvement of Mitsubishi Corporation highlights the increasing role of traditional industrial giants in the digital infrastructure space, providing the necessary capital and local real estate expertise to scale these power-intensive projects.
Ultimately, the NRT14 certification reflects a broader trend where the data centre is no longer just a "warehouse for servers" but a specialized laboratory for AI. As U.S. President Trump’s trade and technology policies continue to shape global supply chains, Japan’s role as a stable, high-tech partner for U.S. firms like Digital Realty and NVIDIA becomes even more pivotal. The success of NRT14 will likely serve as a blueprint for future deployments across Digital Realty’s global footprint, which now spans over 300 facilities in 25 countries, as the industry moves toward a liquid-cooled, AI-first future.
