MC Digital Realty is a 50/50 joint venture between Mitsubishi Corporation and Digital Realty Trust that sells colocation, data center space, and interconnection services exclusively within Japan, concentrated in the two most important national data center markets: Greater Tokyo and Osaka. As of 2026 the company operates data center campuses in Mitaka (west Tokyo), Inzai City in Chiba Prefecture (its NRT campus), and Ibaraki and Minoh cities in Osaka Prefecture (its KIX campus), with total capacity across these sites approaching or exceeding 100MW on the largest campuses. Its most distinctive recent move is building out AI-ready, high-density infrastructure at its newest Chiba facility, NRT14, which was certified under NVIDIA’s DGX-Ready Data Center program to support Blackwell-generation GPU systems. Formed in September 2017 with roughly $1.8 billion earmarked for portfolio growth, the venture combines Mitsubishi’s local real estate and IT knowledge with Digital Realty’s global data center design, construction, and operating expertise.

AI Data Centers
MC Digital Realty's newest facility, NRT14 on its NRT campus in Inzai City, Chiba, was built specifically with AI workloads in mind. It uses hybrid liquid- and air-assisted cooling configurable up to roughly 70kW per rack, and in 2026 it became one of the first data centers in Japan certified under NVIDIA's DGX-Ready Data Center program to host DGX GB200 and other Grace Blackwell-based systems. The company has framed this as part of a broader push to expand AI infrastructure across its Japan portfolio, though this level of AI-specific certification has so far been publicly confirmed for NRT14 rather than its older buildings.
