Digital Realty has begun construction work on a data center at its Osaka campus in Japan.

Dubbed KIX15, the building will add 24MW of capacity to the KIX Campus located in Ibaraki City, Osaka Prefecture.

KIX15 is being developed through the MC Digital Realty (MCDR) joint venture, a 50/50 joint venture with Mitsubishi Corporation, and will be the fifth building at the campus.

Operations are expected to begin in Q4 2028. The new data center will bring the MCDR's total capacity in Japan to 220MW of IT capacity.

Serene Nah, managing director and head of Asia Pacific, Digital Realty, said: “Japan is a strategic market for Digital Realty and a key part of our long-term growth in Asia Pacific. Our continued investment in Japan reflects both our confidence in the market and our commitment to building the infrastructure customers will need for the long term.

“KIX15 is the next step in that commitment. As customer requirements become more distributed and complex, the combination of local scale and global reach will become increasingly important.”

Kohei Yamashita, representative director and CEO of MC Digital Realty, added: “Kansai has a growing opportunity to play a larger role in Japan’s AI economy. 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.”

The data center will be designed to support hybrid air- and liquid-cooling technologies.

Earlier this year, Digital Realty added a third data center to its NRT campus in Inzai City, Japan, located approximately 71km (44 miles) from downtown Tokyo. Work on the 31MW NRT14 began in May 2024.

The company also has a fourth data center in the Tokyo region, dubbed HND10.
