KIX15 is the fifth building of the KIX Campus that MC Digital Realty has been developing in the Saito area, and the company frames it as part of the Kansai AI Infrastructure Co-creation Project, which works on power, cooling and communications infrastructure for AI-oriented computing equipment.
The design reflects what generative AI demands: because it requires far more computation than ordinary processing, the facility is planned with larger server power capacity and cooling equipment, including liquid cooling alongside the conventional air-based approach. The operator expects AI-related companies and cloud service providers to take up the space, and plans to work with multiple telecom carriers so tenants can reach data centers in Osaka and key sites in Japan and overseas at high speed.
MC Digital Realty itself was established in 2017 by Mitsubishi Corp. and U.S. data center company Digital Realty as an equal-investment joint venture, running domestic data centers and inter-company communications services.
