Colt Data Centre Services (DCS) says that one of its co-owners, Fidelity, has agreed with Mitsui & Co. and Mitsui & Co Asset Management Holdings to create a 50:50 joint venture to address the need for hyperscale data centers in Japan. Colt DCS will serve as the exclusive service provider for the design, development, operations and customer service management for the venture, which will focus (at least initially) on the Tokyo and Osaka regions.
Mitsui & Co., Realty Management Ltd., a private real estate fund management subsidiary of Mitsui, will serve as the asset manager for the joint venture. That arm of Matsui will be responsible for structuring, financing, land sourcing, development support, and Japanese customer marketing.
The joint venture will grow Colt DCS’s existing footprint in Japan, which includes 50 MW of built capacity, to 140 MW. “Japan remains a strategic country of focus for our regional expansion, where the demand for large-scale data center capacity outstrips supply,” commented Niclas Sanfridsson, CEO of Colt DCS. “Whilst Colt DCS already has a solid reputation in the market for working with the world’s largest hyperscale cloud providers and multinational companies, the partnership with Mitsui and its strategic alliances will provide new opportunities for us to further penetrate the domestic enterprise sector and accelerate our land banking strategy.”
“Data centers play a critical role in the digital transformation of businesses across the globe, and the demand for high-quality and environmentally conscious hyperscale data centers is huge,” added Shinsuke Waka, general manager of the Financial Business Division of Mitsui & Co. “Through the management of the Mitsui Fund and our joint venture, Mitsui will utilize its unique financial and industrial capabilities to respond jointly to these needs with its global prestigious partners.”
