ESR and Colt Data Centre Services have entered into a joint venture to develop the first phase of a 130 MW1 hyperscale data centre site in Minoh City, Osaka, Japan. The first phase, comprising 65 MW1, will be designed and built by the ESR-Colt DCS joint venture and operated by Colt DCS. Strategically located in APAC's second largest data centre market, the campus will support Japan's accelerating public cloud adoption, digital transformation, and artificial intelligence solutions.
Site preparation work is already underway, with initial data centre building construction scheduled to begin in 2027 and expected to be ready for service in late 2029. The partnership brings together Colt DCS' proven operational excellence and over 25 years of development experience in Japan with ESR's strong in-market development expertise and supply chain partnerships to provide high-quality data centre solutions for customers. Colt DCS opened its Osaka Keihanna data centre in 2023 and ESR's first hyperscale asset, OS1, within its Cosmosquare Data Centre campus in Osaka, completed commissioning in 2025.
The Minoh site spans approximately 140,000 square metres of land that ESR-Colt DC S joint venture has acquired and rezoned for this major redevelopment project, in partnership with the local government. With a strong focus on ESG and local urban regeneration, the initial data centre forms part of the joint venture's broader vision for a large-scale data centre site in MinohCity. The master plan for the site significantly improves and extends local road connectivity and will provide community amenities, such as an international school, local park, retail, and shared facilities.
In line with ESR and Colt DCS' green data centre development goals, the ESR-ColtDCS joint venture is aiming for LEED Gold certification.
