Goodman Group (ASX:GMG) 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 centre campus in Greater Tokyo. The customer is not named in the announcement.
Goodman acquired the 45-hectare site in 2022 and will develop, own, fit out and operate the facility, which is currently under construction and expected to be ready for service in early 2028.
Securing this anchor tenant unlocks the broader campus and validates Goodman’s data centre strategy in a supply-constrained metropolitan market where scarce grid capacity is the key differentiator.
Inside the deal: what Goodman has secured
The lease de-risks the first phase of the campus by locking in the two inputs that are hardest to obtain in metro data centre markets: secured power and diverse fibre connectivity. The core terms and infrastructure already in place include:
-
20-year lease signed with a global hyperscale customer
-
First 50 MW phase of a 1 GW campus
-
Facility to be fully fitted and operated by Goodman
-
Power secured from TEPCO
-
Multiple exclusive dark fibre routes to Greater Tokyo’s main interconnection points, for Goodman’s exclusive use
-
Site-wide civil works complete; facility under construction
-
Ready for service in early 2028
With grid power and fibre routes already secured, delivery risk on the first phase is materially reduced. These are the binding constraints in metro data centre markets, and having them in hand ahead of construction is a meaningful competitive advantage.

Why grid connection is the real bottleneck
The value of metro-adjacent data centre capacity has increased sharply, and the announcement points to a structural shift in how demand is distributed. As AI workloads move from training to inference, demand is concentrating in metropolitan markets close to end users, while cloud demand continues to grow.
That concentration creates a supply problem. According to Goodman, the binding constraint in these markets is grid connection capacity where data centres are required, and that capacity takes years to secure. Sites adjacent to major population centres, such as Tsukuba Tech Central, are therefore described in the announcement as highly sought after and “unique.”
For investors, the read-through is straightforward. Goodman already holds the scarce inputs, being power, fibre and completed civil works, giving it a delivery position that competitors cannot quickly replicate in a market where lead times run into years.
Efficient, community-conscious design
The campus has been designed with efficiency and local impact in mind. Key features described in the announcement include:
-
An efficient cooling design that uses industrial water, so the campus will not draw on Tsukuba’s groundwater.
-
All plant sits within acoustically enclosed structures to minimise noise.
-
Power is drawn from grid electricity on new power infrastructure with no impact to other users, with standby generators reserved for rare emergency use only.
-
Each data centre is designed for AI and cloud workloads, with cooling able to accommodate liquid-cooled deployments and energy performance exceeding Japan’s latest efficiency standards.
-
Goodman continues to work with customers and local utilities on renewable electricity supply for the campus.
Alongside the technical design, Goodman is investing in local amenity as evidence of its long-term commitment to Tsukuba. On the southern side of the site, the company is constructing and will manage, at no cost to the City, a disaster-prevention hub and public amenity area of approximately 45,000 sqm.
Designed by award-winning Tezuka Architects, the space retains and transplants existing trees and adds a plaza, cafés and shops, an emergency warehouse, and a dedicated water source for use in a disaster. The landscaping plan incorporates the planting of many thousands of new trees and plants.
Management commentary
Paul McGarry, Head of Asia, Goodman
“Securing this global hyperscale customer unlocks Tsukuba Tech Central as a premier data centre hub in Tokyo. We are already in advanced discussions with customers over the next phases at the campus.”
McGarry also described the campus as a long-term investment in Tsukuba City, noting that construction runs in stages using local contractors and specialist trades, with each phase adding permanent skilled roles across operations, engineering, maintenance and security.
A deepening data centre platform across Asia
The lease fits within Goodman’s broader Asian data centre footprint, which the company has built over more than two decades. Key elements of that platform include:
-
More than 20 years developing and managing property in Japan
-
More than 300 MW of data centre projects at Goodman Business Park in Inzai
-
Appointment in May 2026 as lead development partner for a proposed data centre campus in Sagamihara City
-
A position in Hong Kong where Goodman holds approximately 30% of market capacity, with ~400 MW under management on completion of projects currently under construction
Goodman Group is the largest property group on the ASX and a top 20 entity by market capitalisation, per the announcement, giving it the balance sheet and capital partnerships to fund a long-duration development pipeline.
What comes next
Advanced discussions are underway for additional phases across the 1 GW campus, with construction running in stages using local contractors and the first phase expected to be ready for service in early 2028.
Each secured phase progressively converts the 1 GW campus into contracted, long-duration income. While no lease value, rent or financial return has been disclosed, the direction of travel is a positive read-through for Goodman’s data centre growth pipeline, anchored by a 20-year commitment from a global hyperscale customer in one of the world’s most supply-constrained data centre markets.
