Status: Announced / In Development | Location: Yamagata-4910-21 Matsuuracho, Imari, Saga 849-5263, Japan
The DayOne Imari City Data Center is a 200 MW hyperscale and artificial intelligence infrastructure campus located at 4910-21 Yamagata in Matsuuracho, within the Imari East Industrial Park in Saga Prefecture, Japan. Developed by Singapore-headquartered DayOne, the multi-building project spans an industrial site footprint of 133,000 square meters. Its scale and focus on AI infrastructure make it a significant development in Japan’s expanding data center market, while its location in Kyushu represents a major expansion beyond the country’s primary data center markets of Tokyo and Osaka. The campus is positioned to support growing demand for cloud computing, high-performance computing, and data-intensive AI workloads.
The planned 200 MW capacity provides a substantial power allocation for large-scale digital infrastructure, supporting the computing resources required by hyperscale cloud platforms and advanced AI applications. As organizations deploy increasingly sophisticated machine learning systems and process larger volumes of data, demand is growing for facilities capable of accommodating high-density computing equipment. DayOne’s multi-building approach provides a campus-scale development framework that can support infrastructure deployment across the site as requirements evolve. The project also places data center investment in Saga Prefecture, extending Japan’s digital infrastructure development into Kyushu.
Kyushu’s emerging technology and semiconductor ecosystem provides an important regional context for the development. Semiconductor manufacturing and related technology industries generate demand for reliable computing, data processing, and connected digital services. Establishing hyperscale infrastructure in this region can help diversify Japan’s data center geography and bring additional capacity closer to businesses and technology operations outside Tokyo and Osaka. Specific details about the campus’s IT load, renewable energy sourcing, cooling systems, and construction schedule have not been provided. Nevertheless, the combination of a 133,000-square-meter site, planned 200 MW capacity, and AI-focused development makes the DayOne Imari City Data Center a major addition to Japan’s digital infrastructure landscape, strengthening DayOne’s presence in the country and supporting the growth of cloud and AI computing across Kyushu.
