AT TOKYO CC3 (Chuo Dai-3 Center) is the newest building on AT TOKYO's Chuo data center campus, located in the Shibaura/Shinagawa area of Minato-ku, Tokyo, distinct from the operator's older Toyosu-based CC1/CC2 buildings. Construction completed on May 28, 2024, with commercial service starting July 1, 2024. The building sits on an approximately 8,000 sqm site with about 35,000 sqm of floor area and a disclosed receiving power capacity of 40 MW, one of the larger power figures AT TOKYO has published for a single building, laid out across roughly 3,000 racks. As the most recent addition to the Chuo campus, CC3 extends AT TOKYO's core Tokyo interconnection footprint closer to Tokyo Bay, complementing the older CC1/CC2 buildings in Toyosu and the operator's Fuchu and Kansai (Osaka) campuses. No Tier rating, PUE, or third-party certification is disclosed in the press materials available for this building; cooling type is not itemized beyond standard facility-level descriptions.
