Stack Infrastructure and APAC real asset manager ESR Data Centres have announced a joint venture to develop a 72MW data center campus in Osaka, Japan. The new facility, which will be run under the STACK brand name, would expand the APAC partnership between STACK and ESR, which already includes a 48MW data center project in Incheon, Korea.
This new 72MW data center will be located in the eastern suburb of Osaka known as Keihanna. The first of the three buildings will begin construction in Q4 2023 and be completed by Q2 2025.

The strategically positioned data center campus would come with excellent network and power access to guarantee high reliability. The scalability to meet future expansion expectations is offered to hyperscale, cloud, and enterprise clients through several solution options, from colocation to custom build-to-suit. Higher rack densities and industry-leading PUE, WUE, and building standards would support evolving workloads while achieving sustainability targets.
“Osaka is STACK’s sixth APAC market in 12 months since our entrance into the region, including the expansion of our footprint in both Japan and Australia to over 100MW each,” said Pithambar (Preet) Gona, Chief Executive Officer of STACK APAC. “This campus further deepens our partnership with ESR, allowing us to combine our capabilities to meet our clients’ strategic requirements in existing and emerging Tier 1 data center markets.”
Investments in Korea, Japan, Australia
“ESR’s strong regional development capability in Tier 1 data center markets ensures we are well-positioned to continue to aggressively develop data center facilities across Asia Pacific,” said Diarmid Massey, CEO at ESR Data Centres. “Our partnership with STACK enables us to leverage our respective strengths to target hyperscale customer growth in key markets.”
This achievement comes in the wake of recent announcements about STACK’s entry into the APAC market with the opening of its regional headquarters in Singapore, as well as its expansion into new markets with the opening of a 48MW data center in Seoul, Korea, a 36MW campus in Inzai, Japan, and 124MW across Melbourne, Canberra, and Perth in Australia.
With over US$1 billion in equity commitments for investments in digital infrastructure, ESR is currently developing a portfolio of “environmentally friendly and market-leading” data center solutions in Hong Kong, Osaka, Tokyo, Seoul, Sydney, Mumbai, and Singapore. This work is being supported by ESR’s recently announced inaugural data center investment fund (ESR DC Fund 1).
