STT Tokyo 1 Existing Operations

Operational last observed as of 2026-08-21 · Authoritative status update

English counterpart confirms continuing operations since commencement. Up to 32 MW when fully operational and approximately 70 MW for the completed two-building campus are future or aggregate scope; neither is adopted as current operating load. Design PUE is not measured operating performance. evidence

Page 1 names STT Tokyo 1 as the first of two buildings in its campus within Goodman Business Park. Page 2 lists 2-2-5 Kaguro-Minami, Inzai-shi, Chiba 270-1369. The URL indicates an April 2025 revision and copyright is 2025; exact publication day is unknown. Its LEED Gold (2024) label does not establish a grant day. No 32.4 MW, voltage, floor area or design PUE observation is normalized. evidence

ST Telemedia Global Data Centres · publication date not stated

Current operator page separately names Tokyo 1 and Tokyo 2 within the same STT campus at Goodman Business Park, marks Tokyo 2 under development, and links the captured exact Tokyo 1 factsheet. Retrieval does not refresh physical status and no Tokyo 2 status project is proposed. evidence

ST Telemedia Global Data Centres · publication date not stated

Original certification issued May 24, 2024 identifies Goodman Business Park Stage 7 new construction as a data center and office at Kaguro-Minami 2-chome 2-5, 2-8 and 2-9. The operator factsheet address 2-2-5 is included in that property address. The certificate supports an address and historical project-name bridge; it supplies no selected geometry. Its May 2024 completion date is explicitly planned and is not an achieved completion or current status. evidence

Precision scope: Google Maps selected place point for STT Tokyo 1, used as a labelled property locator for the STT Tokyo Inzai Campus within Goodman Business Park. It does not establish a surveyed building or campus boundary, entrance, individual data hall or exact Tokyo 2 location.
Horizontal uncertainty: Not reported
Google Maps supplies no measured horizontal accuracy for the selected place. Decimal places are retained from its selected-object record and do not imply survey precision or known offsets to operating data halls.
Geometry evidence: 4b5bdf8e

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
