APAC-focused data center developer DayOne has commenced construction on its second campus in the Japanese capital, marking a significant expansion of its presence in one of Asia's most active digital infrastructure markets. The move underscores the accelerating demand for hyperscale and colocation capacity in Japan, driven by cloud adoption, enterprise digitalization, and the growing compute requirements of artificial intelligence workloads.
The company announced it has broken ground on Phase I of the DayOne Kodaira Data Center in Tokyo. The initial phase is designed to deliver 15MW of IT capacity, with the full Kodaira campus planned to provide a total of 42MW once completed. The project represents a substantial addition to Tokyo's data center supply pipeline, which has seen tightening availability and rising land costs in recent years.
DayOne CEO Jamie Khoo framed the groundbreaking as a broader strategic milestone. "Today's groundbreaking marks a beginning, not only of a new facility, but of DayOne's long-term commitment to Kodaira and to Japan's digital future," Khoo said.
The Kodaira development follows DayOne's ongoing work at the Fuchu Intelligent Park campus, also in Tokyo, where construction began last year. Developed alongside real estate investment firm Gaw Capital, the Fuchu site is slated to offer 80MW across 66,360 square meters (714,293 square feet). The first phase at Fuchu will feature a nine-story building with 18MW of capacity and is expected to reach core and shell readiness by mid-2027.
DayOne was spun out of Chinese data center operator GDS in 2025 and has since positioned itself as a dedicated APAC platform. Its portfolio currently comprises more than 500MW of data center capacity in service and under construction, alongside an additional 500MW held for future development. The company's footprint spans Hong Kong, Singapore, Malaysia (Johor), Indonesia (Batam), and Japan (Tokyo).
The Kodaira groundbreaking reflects the broader race among regional operators to secure land, power, and connectivity in Tier 1 Asian markets. As AI-driven demand continues to outpace supply in Tokyo and other major hubs, developers with established pipelines and strong capital backing are positioned to capture long-term hyperscale and enterprise leasing activity.
