ESR eyes fourth data centre in Japan

ESR Group on Thursday (May 16) announced plans to develop its fourth data centre in Japan, a 60-megawatt project located in Ariake in central Tokyo.

The asset manager currently has three data centres in the country: Cosmosquare Data Centre campus in Osaka; Keihanna Data Centre campus in Kyoto; and Higashi Kurume Data Centre in Tokyo.

ESR co-founder and co-chief executive officer Stuart Gibson said data centres are a key growth engine for the group, and its Ariake development will expand its portfolio across Japan and Asia-Pacific.

ESR data centres CEO Diarmid Massey said: “Time-critical applications and future workloads in urban areas have created a need for data centres in areas such as Ariake, which are closer to urban population centres and existing data centre clusters.”

He added that there is increased demand for modern, energy-efficient data centres to replace ageing digital infrastructure in Tokyo and Osaka.

Construction of the new data centre will commence in the second quarter of 2026, and is targeted for completion by Q4 2028.
