DayOne, a Singapore-based data centre developer and operator, along with Gaw Capital Partners, has started construction on the first phase of a data centre project in Japan.
The project is located within Gaw Capital’s 80MW data centre campus at Fuchu Intelligent Park, which is less than 30km from central Tokyo.
This initial phase features a nine-storey building with ten data halls, providing an IT capacity of 18MW. The building's core and shell are set to be ready by mid-2027.
NEC Facilities has been selected as the architect, with HASEKO serving as the main contractor.
Gaw Capital Partners managing director and Asia (ex-China) data center platform head Nicholas Toh said: “This collaboration merges Gaw Capital's global real-estate experience with DayOne's expertise in operating high-performance data centres, illustrating our joint dedication to crafting a world-class infrastructure to meet the escalating data-processing demands catalysed by the rise of generative artificial intelligence (AI) in the region."
According to DayOne, the facility will integrate advanced cooling systems and renewable energy resources.
Specifically, it seeks to obtain certifications such as Comprehensive Assessment System for Built Environment Efficiency, Leadership in Energy and Environmental Design, and International Organization for Standardization 50001 to enhance sustainability and operational efficiency.
DayOne CEO Jamie Khoo said: “This campus will deliver the foundational infrastructure needed to support the rapid growth of cloud, AI, and next-generation technologies in Japan and the region.
“It also represents an important step in expanding our global platform, following our successful execution of the SIJORI (Singapore-Johor-Riau Islands) strategy across Southeast Asia."
DayOne specialises in developing digital infrastructure for major industry players. Its other operations span key locations such as Singapore, Johor in Malaysia, Batam in Indonesia, Bangkok in Thailand, and Hong Kong.
Late last month, DayOne initiated its first data centre project in Singapore, focusing on AI and high-performance workloads.
Scheduled for completion in 2026, this 20MW site will use green infrastructure as part of Singapore’s wider plan to enhance AI-ready facilities in tropical climates. It will also pilot hydrogen-based power via solid oxide fuel-cell generation.
Officially launched on 1 January 2025 following its Series B funding round, DayOne emerged from GDS International as an independent entity.
The company has secured approximately $1.9bn through Series A and B financing, supported by investors such as SoftBank Vision Fund and high-profile figures, including Kenneth Griffin of Citadel.
