Colt Data Centre Services (Colt DCS) has launched its new hyperscale data centre, Inzai 4, in Tokyo, Japan. This expansion is the second site developed under the joint venture between Fidelity Investments and Mitsui & Co., Ltd.. This latest site reinforces Colt DCS’ commitment to meeting the growing demand for data centre capacity and public cloud services in Japan and the Asia-Pacific region.

The first phase of the development is complete, with 4.8MW now operational. Once fully built, the site will deliver 20MW, increasing Colt DCS' total capacity in Inzai to 70MW. Inzai 4 is fully pre-let, highlighting the strong demand for Colt DCS’ solutions. With a global presence and flexible solutions, Colt DCS remains a top data centre partner for its customers.

The site was developed following Colt DCS’ Global Reference Design (GRD) guidelines. This means incorporating various low embodied carbon principles such as; reducing water waste during the cooling process, installing cooling chillers with low Global Warming Potential (GWP), and building the site structure with minimal steel and concrete usage.

Colt DCS was the first provider to launch a hyperscale data centre in the Inzai area in 2011 and has continued to invest in the region, with plans already underway for its Inzai 5 facility. The area's stable bedrock, dense fibre connectivity, efficient rail links, proximity to Tokyo, and supportive local government make it a prime location for data centre expansion.

Niclas Sanfridsson, CEO at Colt DCS, said: "The continued growth in digital services has created strong demand for hyperscale data centres in Japan. Inzai 4 is a testament to our commitment to meeting this demand and supporting the digital economy in the Asia-Pacific region. We are proud to contribute to the growth of the local community and remain a trusted partner for our customers worldwide."
