The addition of the new facility brings total IT capacity at the Osaka campus to more than 70 megawatts
A data centre joint venture between Mitsubishi Corporation and Digital Realty has opened a fourth building at its Osaka campus, with the latest phase offering up to 21 megawatts of IT capacity.
The addition of the new facility, dubbed KIX13, brings total IT capacity at the 23,000 square metre (247,570 square foot) Osaka campus to more than 70MW, said MC Digital Realty, which is shared 50:50 between Japan’s Mitsubishi and the US data centre giant.
The three-storey building is reinforced with seismic isolation systems for resilience against earthquakes and provides access to Digital Realty’s PlatformDigital community of enterprises and cloud and network service providers, the company said in a release.
“The completion of KIX13 takes the MCDR Osaka campus to the next level, offering customers a spectrum of solutions that break down barriers to achieve our goal of creating a global connected-data community,” said Serene Nah, managing director and head of Asia Pacific at Digital Realty.
International Gateway
As Japan’s second-largest data centre market, Osaka is a hub for financial and co-location users and a gateway for international exchanges. The carrier-neutral Osaka campus forms a pillar of Digital Realty’s strategy to strengthen its network of connected communities in Asia Pacific and globally, the company said.

“We have been working to create a next-generation interconnection platform that goes beyond the ‘traditional’ data centre business to create new business opportunities and value-added services for our customers,” said Bampo Tezuka, representative director and CEO of MC Digital Realty. “Our Osaka campus offers flexible scalability, robust power supply capacity suitable for high-load servers and stringent security compliant with international standards.”
NYSE-listed Digital Realty operates as a REIT and has more than 300 facilities in 27 countries. The Texas-based company had $41.5 billion in assets, including $31 billion in real estate, at the end of December 2022, according to unaudited results.
The trust’s Asia Pacific data centres include assets in Japan, China, South Korea, Singapore and Australia. APAC boss Nah joined Digital Realty in January after resigning as chief financial officer and executive director on the board of Kerry Properties, the Hong Kong-based builder controlled by the family of Shangri-La Hotels tycoon Robert Kuok.
Big in Japan
Japan continues to attract interest from data centre developers at home and abroad, with ESR announcing last December that it was teaming up with US-based operator Stack Infrastructure on a 72MW Osaka campus targeting hyperscale customers.
The joint venture project will bring Hong Kong-listed ESR’s Japan portfolio to 168MW, with Osaka also being home to the company’s first-ever data centre investment: the 96MW ESR Cosmosquare hyperscale campus under development in the Nanko Kita area near the city centre.
Other announced projects include Macquarie-backed AirTrunk’s second hyperscale data centre in Japan, a 110MW development in western Tokyo, and local builder Hulic’s first data centre, an eight-storey facility in Tokyo’s Nihonbashi commercial district.
Google announced last October that it would build its own data centre in Inzai City east of Tokyo, marking the tech giant’s third server shed in Asia after facilities in Taiwan and Singapore.
