Digital Realty's Japan expansion is adding capacity for cloud and high-density AI computing, with its Osaka KIX15 facility scheduled to begin operations in the fourth quarter of 2028.
MC Digital Realty is an equal joint venture formed in 2017 by Digital Realty and Mitsubishi Corporation.
Digital Realty's Japanese operations span eight live sites and roughly 170 MW of IT capacity. That figure measures the power servers can draw, rather than a data center's total electricity consumption. Once KIX15 is complete, the joint venture's projected footprint is 10 facilities and about 220 MW in IT capacity. Those figures cover different groups of sites: 170 MW is Digital Realty's current Japan total, while 220 MW is the joint venture's projection.
NRT14 began operating in April 2026 and supports 150 kW per rack. It is an early Japanese holder of NVIDIA DGX-Ready status, a certification indicating that a facility can host NVIDIA's advanced AI systems.
Construction began Oct. 7, 2026, at KIX15 near Osaka. The design calls for 24 MW and cooling through both air and liquid systems to support dense AI computing; its intended customers include hyperscalers and cloud service providers. Operations are scheduled to start in the final quarter of 2028.
