CyrusOne KEP, a joint venture between global data center provider CyrusOne and Kansai Electric Power Co. (KEPCO), has officially broken ground on its first data center in Japan. The project, named CyrusOne KEP OSK1, is located in the Kansai region’s Keihanna Availability Zone, a strategic hub for data centers. The facility will have an incoming power capacity of 70 MVA and will deliver 48MW of IT capacity across 11,562 square meters (124,452 square feet) of technical space. The project will be built in three phases, with the first phase expected to be operational by Q1 2028.
The new hyperscale data center will feature six 8MW data halls across four floors and prioritize sustainability and environmental impact reduction throughout its lifecycle. The joint venture between CyrusOne and KEPCO aims to reach a total business scale of 900MW incoming power within the next decade, further supporting the region’s digital infrastructure needs. The facility will also generate job opportunities in the Kansai area during its construction and operation phases.
