ESR has completed the building work of its data center in Osaka, Japan.

The APAC real estate firm this week announced that it has successfully completed the core and shell of its Cosmosquare OS1 data center project in Nanko Kita.

The OS1 facility will be ready for service in May 2025 and once fitted out, it will provide 25MW of capacity.

The newly completed data center is the first hyperscale facility within ESR’s 130MW campus. At full build-out, the $2 billion campus will total three buildings.

Stuart Gibson, ESR Group co-founder and co-CEO, said: “We are delighted to reach this important milestone in our first Osaka data center development, creating a campus-style asset with expansion capability in a prime location of a high growth market. This development is a flagship project in ESR’s strategic and accelerated rollout of data centers to capitalize on the unprecedented demand for high-performing digital infrastructure across key markets in APAC.”

ESR has traditionally been focused on logistics real estate, but has made a number of investments in the data center space since 2021. The company said it has 575MW of committed data center sites in key markets across APAC, with a pipeline of more than 2GW worth of land and projects.

The company took over the Osaka site in April 2021.

Diarmid Massey, CEO of ESR Data Centres, added: “ESR’s Cosmosquare campus, which is backed by ESR DC Fund 1, is a notable showcase of our acceleration in strategy to cater to the regional growth of Cloud and Digital Infrastructure. We are fulfilling the growing customer need for data center capacity, that is being turbocharged by the outsized Artificial Intelligence demand that is quickly migrating to APAC. Our pipeline of hyperscale data centers will deliver next-generation environmentally focused solutions to our end customers and business partners to power the growth of digital infrastructure in Osaka and across APAC.”

The company currently has three other sites in development in Japan; the 100MW Keihanna data center campus in Kyoto; and 30MW Higashi Kurume, and 60MW Ariake facilities in Tokyo.

ESR has developments planned in Hong Kong, Malaysia, South Korea, and Australia. ESR subsidiary ARA Asset Management also has a data center footprint through its Logos Group unity, which partnered with Pure Data Centres for a 20MW facility in Indonesia.
