Goodman Group, a global provider of digital infrastructure, has signed a 20-year lease with a global hyperscale customer for the first 50 MW phase of Tsukuba Tech Central, its 1 GW data center campus in Greater Tokyo. While the identity of the customer has not been revealed yet, power has been secured from TEPCO and diverse dark fibre routes to Greater Tokyo’s main interconnection points for Goodman’s exclusive use.
Goodman acquired the 45-hectare site in 2022 and will develop, own, fit out and operate the facility, which is under construction. It will be ready for service in early 2028. In a press release, Goodman further revealed that campus employs an efficient cooling design that uses industrial water so will not draw on Tsukuba’s groundwater. Moreover, the plant sits within acoustically enclosed structures to minimize noise.
Paul McGarry, Head of Asia, Goodman, said, “Securing this global hyperscale customer unlocks Tsukuba Tech Central as a premier data center hub in Tokyo. We are already in advanced discussions with customers over the next phases at the campus”.
Mindful of growing concerns about power use by data centers, power for this project will be drawn from grid electricity on new power infrastructure with no impact to other users and standby generators are for rare emergency use only. Moreover, Goodman says it is continuing to work with its customers and local utilities on renewable electricity supply for the campus.
This is significant because, as AI workloads shift from training to inference, demand is concentrating in metropolitan markets close to users. Cloud demand also continues to grow, making locations such as Tsukuba Tech Central, adjacent to major population centers, highly sought after. The binding constraint in those markets is grid connection capacity where data centers are required, which takes years to secure.
Goodman has developed and managed property in Japan for more than 20 years, including more than 300 MW of data center projects at Goodman Business Park in Inzai, In May 2026, it was appointed lead development partner for a proposed data center campus in Sagamihara City. Japan forms a key part of Goodman’s data center platform in Asia which includes Hong Kong where Goodman has ~400 MW under management on completion of projects currently under construction.
