Colt Data Centre Services (Colt DCS) has launched another data center in Tokyo, Japan.

The company this week announced the launch of its latest hyperscale data center, Inzai 4.

Colt broke ground on the 8,750 sqm (94,185 sq ft) Inzai 4 site in April 2023. The first 4.8MW phase of the development is complete and operational. Once fully built out, the site will deliver 20MW, taking Colt’s total capacity in Inzai to 70MW. The facility is fully pre-leased.

Niclas Sanfridsson, CEO at Colt DCS, said: "The continued growth in digital services has created strong demand for hyperscale data centers 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."

Colt launched its first Inzai data center back in 2011. This expansion is the second site developed under the joint venture between Fidelity Investments and Mitsui & Co., Ltd. The first development under the JV, in Osaka Keihanna, opened in March 2023.

In July 2021, Japanese conglomerate Mitsui and investment firm Fidelity formed a joint venture to build hyperscale data centers in Japan that would be operated by Fidelity-owned Colt.

Colt currently operates two data centers in Osaka and a total of five other facilities in Tokyo.

Colt also has seven facilities across Europe; three in London, UK; two in Frankfurt (with a third in development), Germany; and one each in Paris, France, and Rotterdam, the Netherlands. It is also developing a large campus in Mumbai, India. In January 2022, the company said it had acquired ten new parcels of land across Europe and APAC for new data center developments, including in Japan, but didn’t provide details.
