ESR announce new 20MW data centre development in West Tokyo


ESR Cayman Limited (ESR) has acquired a key data centre asset in Higashi Kurume, one of Tokyo’s most established data centre clusters, comprising three office buildings within a total site area of 20,900 sqm and enabling the creation of a 20 megawatt (MW) IT load data centre.

The new facility is expected to commence operations in September 2025. It will provide 20 MW’s of data centre capacity to support the community of enterprises located in West-Central Tokyo including existing operators, as well as new market entrants in the wider, supply-constrained Tokyo market.

Jeffrey Shen and Stuart Gibson, ESR co-founders and co-CEOs, remarked: “As the largest New Economy real estate platform in APAC, ESR continues to accelerate the expansion of our digital infrastructure ecosystem across APAC. We are tremendously excited to announce our latest data centre project in such a prime location in Tokyo following our acquisition of a multi-phase 98MW development project in Nanko, Osaka in 2021. As a Group, we will continue to leverage our hyperlocal presence that provides unparalleled access to unique land sourcing, zoning and power approvals as well as best-in-class development expertise to differentiate ourselves from our peers.”

Diarmid Massey, CEO, Data Centres of ESR, added: “Tokyo is the primary hub for international firms to access the Japanese market. Its geographical location as the most prominent technology and financial market situated in the northwestern part of Asia has resulted in it becoming the first landing point for a sizable number of submarine cables to connect the western United States to the rest of Asia. Japan, which is ranked as the third most attractive location for data centres globally due to the country’s very high data consumption, mobile broadband penetration and large market size, remains one of the largest data centre markets in the APAC region and hence a highly important strategic market for ESR.”

ESR says that ESG sits at the heart of its business, and the Group says it is committed to integrating responsible low carbon innovation into its latest data centre developments in Higashi Kurume to help achieve energy efficiency and to reduce the carbon footprint.
