STACK Infrastructure, a hyperscale data center developer and operator backed by IPI Partners, a digital infrastructure private equity firm, in-partnership with Oaktree Capital Management, via its real estate funds, today announced that they are developing a new 36-megawatt hyperscale data center campus in Inzai, part of the Greater Tokyo Area of Japan, which will be known as TKY01.

Notably, STACK Infrastructure’s entry into Japan represents the company’s first project following its expansion into the Asia-Pacific region. Beyond Japan, the company plans to pursue a combination of acquisitions and organic development projects in the Asia-Pacific markets of Singapore, Hong Kong, South Korea, and Australia.

TKY01 – Tokyo, Japan – STACK Infrastructure

STACK Infrastructure’s TKY01 data center development project is located in the city of Inzai, Chiba Prefecture, within the Greater Tokyo Area of Japan.

Within Inzai, STACK Infrastructure’s 2.3-hectare (5.7-acre) land parcel is located in Hara, at the intersection of National Route 464 and Chiba Prefectural Road Route 189. Additionally, this site is adjacent to the BIG HOP Garden Mall Inzai, a shopping center.


At full build-out, STACK Infrastructure’s TKY01 data center campus will comprise two 18-megawatt buildings, totaling 36 megawatts of critical capacity.

Initially, the project will break ground in Q2 2022, with 6 megawatts of capacity expected to be delivered by Q4 2023. Subsequently, STACK notes the possibility for a powered shell with 12 megawatts of capacity. Finally, a future phase of development could comprise a build-to-suit facility with 18 megawatts of capacity.


STACK Infrastructure’s TKY01 data center campus will have high-capacity dark fiber and access to major long-haul fiber carriers for low-latency connectivity. Specifically, the campus will offer two meet-me-rooms with three diverse fiber entrances. For example, carries including NTT, KDDI, Colt, Arteria, Tepco, and SoftBank, will be available on-site.


STACK Infrastructure intends to develop this Tokyo, Japan site to provide scalable and redundant energy supply by connecting to regional substations powered by Tokyo Electric Power Company. Particularly, the company will source power from dual 66kv extra high voltage lines.


STACK Infrastructure is targeting hyperscale and enterprise customers for its TKY01 data center campus. For these customers, STACK is designing its facility to enable higher rack density (i.e., deployments in excess of 8kW per cabinet) and floor loading specifications.

Additionally, STACK Infrastructure is offering its facilities to meet various customer requirements including rack-ready, powered shell, and build-to-suit.
