Digital Realty Begins Construction of 24 MW KIX15 Data Center in Osaka to Expand AI Infrastructure in Japan

By: IDCNOVARegion: East Asia
Digital Realty (NYSE: DLR), the world's largest cloud- and carrier-neutral data center platform, has commenced construction of KIX15, a new 24 megawatt data center at its KIX Campus in Ibaraki City, Osaka Prefecture, Japan, the company announced on October 7, 2026. The project marks a significant step in the company's efforts to deepen its footprint in one of Asia Pacific's most strategically important digital infrastructure markets.

The new facility is being developed by MC Digital Realty, Digital Realty's 50/50 joint venture in Japan with Mitsubishi Corporation. KIX15 will be the fifth data center at the KIX Campus and is scheduled to commence operations in the fourth quarter of 2028. Upon completion, it will bring MCDR's Japan portfolio to 10 data centers, representing approximately 220 MW of aggregate IT capacity across the Tokyo and Osaka metropolitan areas.

The expansion follows the opening of the NRT14 Data Center in Inzai City, Chiba Prefecture, earlier this year. NRT14 is one of the first facilities in Japan to achieve the DGX-Ready Data Center certification, underscoring Digital Realty's push to support AI workloads in the country. KIX15 will operate as part of PlatformDIGITAL, Digital Realty's global data center platform spanning more than 300 data centers across 55-plus metros in over 30 countries on six continents.

Serene Nah, Managing Director and Head of Asia Pacific at Digital Realty, said Japan is a strategic market for the company and a key part of its long-term growth in Asia Pacific. She noted that the continued investment in Japan reflects both confidence in the market and a commitment to building the infrastructure customers will need for the long term, adding that as customer requirements become more distributed and complex, the combination of local scale and global reach will become increasingly important.

KIX15 is a key component of MCDR's Kansai AI Infrastructure Co-Creation Project, an initiative centered on the KIX Campus to support the development of AI infrastructure across the Kansai region. The project combines the expansion of the KIX Campus with stronger domestic and international connectivity and deeper collaboration with telecommunications and technology partners.

Kohei Yamashita, Representative Director and Chief Executive Officer of MC Digital Realty, said Kansai has a growing opportunity to play a larger role in Japan's AI economy, and that realizing that potential will require an ecosystem that can support businesses as they build and scale AI, bringing together computing infrastructure, connectivity and technology expertise.

As adoption of generative AI and cloud services grows, demand is increasing for higher-density computing environments, advanced cooling and reliable connectivity in Japan. KIX15 is designed to support hybrid air- and liquid-cooling technologies, providing a high level of security and campus-based scalability. The facility is expected to serve a broad range of customers, including hyperscalers, cloud service providers and companies deploying AI infrastructure.

Through Digital Realty's ServiceFabric orchestration and interconnection platform and collaboration with multiple network service providers, customers will have access to low-latency connectivity to key locations and cloud services in Japan and more than 300 Digital Realty data centers worldwide. This enables customers to expand into high-power, high-density infrastructure at the KIX Campus while maintaining connectivity with their existing IT environments.
