Completion of Construction of AT TOKYO's Chuo Center #3 (CC3)
Next-Generation Data Center
with Superior Connectivity and Sustainability
Expected to be One of Japan’s Top-Tier Network Hubs

AT TOKYO Corporation (Headquarters: Koto-ku, Tokyo, President and Chief Executive: Tatsuya Izumida; hereinafter “AT TOKYO”) is today pleased to announce the completion of our new data center, AT TOKYO Chuo Center #3 (CC3).

In response to the growing needs for data centers, cloud connectivity, and risk diversification, AT TOKYO has expanded its data center offerings by leveraging its superior connectivity and zero-downtime operations centered largely in the Tokyo and Osaka areas. Recently, the mission of data center operators has broadened to incorporate a focus on sustainability and de-carbonization, including the use of renewable energy and improved efficiency equipment, which have become critical elements for supporting the emergence of AI and other next-generation technologies.

Located in the Shibaura-Shinagawa area, one of major data center clusters in Japan, the CC3 facility will serve primarily as an interconnection hub for public cloud services, IXs, and enterprise partners. It features net zero carbon emission operation *1, and is capable of satisfying demands of large-scale users including hyperscalers with an infrastructure that meets the demands of AI technologies.
Furthermore, in addition to the installation of cable lines from major telecommunications carriers and service equipment from network service providers *2 in Japan and abroad, CC3 will also be connected to optical fiber cables *3 that traverse the Port of Tokyo in order to provide the shortest route to and from the Toyosu-Ariake area, where many IT companies are concentrated, and thus boasting flexible and highly scalable connectivity on a global scale.

Features of CC3

1. Superior connectivity
Located in the Shibaura–Shinagawa area, one of major clusters of IXs in Japan.
Seamlessly connected to our existing data centers via optical fiber cables that traverse the Port of Tokyo.

2. Net zero carbon emissions
Operating with virtually 100% renewable energy. Provision of tracking information attributes available upon customer’s request.

3. Supports AI and other next-generation technologies
Leading edge and highly efficient air-cooled chillers are adopted to handle high temperature exhaust air, allowing a very low PUE*4.

About CC3

AT TOKYO Chuo Center #3

*3: Optical fiber cables for telecommunications traversing the Port of Tokyo to be installed between the Toyosu and Ariake area and the Shibaura and Shinagawa area by AT TOKYO and Arteria Networks Corporation (https://www.attokyo.com/news/20231219.html). Adopting the HDD (Horizontal Directional Drilling) construction technique has enabled installation work across the Port of Tokyo with a sectional distance of approximately 2,000 meters, achieving rapid delivery, lower costs, and the shortest route (ultra-low latency).
*4: Abbreviation of Power Usage Effectiveness. An indicator of energy efficiency ratio calculated by the formula: total electricity consumption in a facility divided by electricity consumption of IT equipment within it.
