• ESR Data Centre Fund 1 has secured US$1.35 billion for digital infrastructure investments, expanding across APAC cities.

ESR Group Limited, a prominent APAC real asset manager, has announced the development of its fourth data centre site in Japan. The 60MW facility in Ariake, Koto-Ku, Central Tokyo, adds to their existing projects: 130MW Cosmosquare Data Centre in Osaka, 100MW Keihanna Data Centre in Kyoto, and 30MW Higashi Kurume Data Centre in Tokyo. Construction begins in Q2 2026, with completion expected in Q4 2028.

Stuart Gibson, ESR Group Co-founder and Co-CEO, said: “Data centres are a key growth engine for ESR, and our Ariake development expands our portfolio across Japan and APAC. Our platform has a significant 1.5-gigawatt (GW) data centre pipeline in key cities including Hong Kong, Osaka, Tokyo, Seoul, Sydney, Mumbai, and Singapore. Japan is one of the largest and fastest growing data centre markets in the world and our Ariake project will be transformational in terms of the amount of capacity it will bring to Central Tokyo.”

Diarmid Massey, CEO of ESR Data Centres, added: “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. In Tokyo and Osaka, there is increased demand for modern, energy efficient data centres to replace aging digital infrastructure. ESR continues to partner with operators and hyperscalers to grow our data centre portfolio across APAC.”

The new Ariake site aims to provide hyperscale, cloud, and enterprise clients with scalable, high-speed services. The facility will support increasing workloads such as AI and machine learning, with reliable energy efficiency and sustainability standards. ESR’s data centre investment fund, ESR Data Centre Fund 1, has secured US$1.35 billion for digital infrastructure investments.
