Osaka Keihanna, Japan – Colt Data Centre Services (DCS)

Colt Data Centre Services’ Osaka Keihanna hyperscale data center will comprise 45 megawatts of power capacity across 452k sqft (42.0k sqm) of total area, once fully built-out. The site is located in Keihanna Science City (officially known as Kansai Science City), an area which spans the Kyoto, Osaka, and Nara prefectures in western Japan.

Site and Facility

Colt’s Osaka Keihanna is located in the Seika & Nishi-Kizu District of Keihanna Science City. Specifically, the land parcel is situated in between Panasonic Corporation (to the West), Keihanna Plaza (to the South), and KEC Electronic (to the North).

Additionally, Colt Data Centre Services (DCS) states that the land was not originally available for purchase by a data center operator. This is because the Keihanna Science City area’s designation is for research and development activities. However, Colt DCS received support from the Kyoto Prefectural authorities to help enable the land acquisition.

Colt’s Osaka Keihanna has a site area of 176k sqft (16.4k sqm), on which it is building a five-story structure. In terms of IT space, the building will have 165k sqft (15.3k sqm) of area for server cabinets.


Colt DCS’ Osaka Keihanna will have 45 megawatts of IT power supplied to the site, allowing for up to 2.6 megawatts to be delivered to each data hall. In terms of power usage effectiveness (PUE), Colt quotes a peak PUE of less than 1.6.


Colt Data Centre Services (DCS) is targeting to have the carrier-neutral facility be ready for service in early 2023.


Colt DCS aims to lease the Osaka Keihanna facility to hyperscale and enterprise customers that have scalable capacity demands.
