Asia-Pacific-focused new economy real asset manager ESR Group has successfully completed the core and shell of its flagship data centre (DC) project, ESR Cosmosquare OS1 Data Centre (OS1), in Nanko Kita, Osaka, Japan.

The newly completed OS1 is the first hyperscale data centre asset within ESR’s 130-megawatt (MW) MW1 campus. Being developed over three phases (OS1, OS2 and OS3), the asset manager’s US$2 billion hyperscale data centre campus strategically sits within 10 kilometres of the major internet and telecommunication exchanges in the Osaka central business district.

This milestone is part of the group’s accelerated data centres strategy to execute 575MW of committed data centre sites in key markets across Asia-Pacific, with a pipeline of more than 2 gigawatts worth of land and projects.

OS1 is slated to achieve Leadership in Energy and Environmental Design (LEED) NCv4 Gold certification. The building is designed with an efficient cooling system to reduce energy use, therefore, minimizing the need for chillers while ensuring high reliability and flexibility for customers.

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

“This development is a flagship project in ESR’s strategic and accelerated rollout of data centres to capitalize on the unprecedented demand for high-performing digital infrastructure across key markets in Asia-Pacific,” says Stuart Gibson, the group’s co-founder and co-CEO.

Diarmid Massey, CEO of ESR Data Centres, adds, “We are fulfilling the growing customer need for data centre capacity, that is being turbocharged by the outsized artificial intelligence (AI) demand that is quickly migrating to Asia-Pacific.”
