KIX15

KIX15 is a 24 MW data centre on the KIX campus in Ibaraki City, Osaka Prefecture. Construction started on 7 October 2026, and the Building is due to come into service in the fourth quarter of 2028, about two years later.

Its developer, MC Digital Realty, is a joint venture of the US operator Digital Realty and the Japanese trading house Mitsubishi Corporation. Digital Realty said KIX15 takes the venture to ten Japanese data centres with roughly 220 MW of IT capacity. The US parent keeps adding Asian capacity in modest blocks; in August 2026 Singapore provisionally allotted it 50 MW at Jurong Island's low-carbon park.

the Building adds capacity in Japan's second data-centre market, which grew around Osaka after the 2011 earthquake pushed firms to keep backup computing away from Tokyo. The government's 2026 information and communications white paper puts about 90% of Japan's data centres in the Kanto and Kinki regions and says it aims to spread them out, without naming a preferred region. A 24 MW block on an existing Osaka campus shows operators still building where their customers are.
