Digital Realty Expands Japanese Campus to 100MW with Third Inzai Data Center
April 8, 2026
Digital Realty has significantly expanded its footprint in one of Asia's key data center hubs with the inauguration of a new facility at its NRT campus in Inzai, Japan. The expansion underscores the sustained demand for critical digital infrastructure in the Tokyo metropolitan region, a major financial and technological center.
The new facility, named NRT14, adds 31 megawatts of capacity to the campus. Construction on the project commenced in May 2024, and the data center is now operational. This addition brings the total combined capacity of the three-building NRT campus—which also includes the NRT10 and NRT12 facilities—to 100MW. The development was executed by MC Digital Realty (MCDR), a 50/50 joint venture established in 2017 between Digital Realty and Japan's Mitsubishi Corporation.
MCDR acquired the land for the Inzai campus in 2019 and has been developing it in phases. The joint venture now operates a portfolio of nine data centers across Tokyo and Osaka, having initially consolidated assets from both parent companies. Inzai City, located in Chiba Prefecture approximately 71 kilometers from central Tokyo, is a primary data center cluster in Japan, hosting facilities from numerous global and regional operators.
The completion of NRT14 solidifies Digital Realty's competitive position in a strategic and densely populated market. Scaling a single campus to 100MW provides significant operational efficiencies and meets the growing requirements of enterprises and hyperscale customers for large-scale, interconnected data center capacity in proximity to Tokyo's business core.
