Japan / Facility
Colt Inzai 1 Data Centre
Operational hyperscale colocation facility in Chiba New Town, Inzai City, serving the Tokyo market. Colt identifies it separately from Inzai 2 and 3 and describes it as the first facility in its Tokyo Inzai campus. Current operator materials report 8 MW IT capacity; a 2019 announcement reports 8.4 MW. Both exceed 5 MW, but the difference remains unreconciled.
Statements retain their dates, definitions and development scope. Do not add these rows together.
| Claim / measurement | Scope and status | As of | Evidence and accounting |
|---|---|---|---|
| 8 MW IT load | Inzai 1 facility Operational · cumulative | 2026-10-09 | Reported claim ↗ Excluded from capacity totals. As-of date is retrieval of the undated current operator page, not a measured load or commissioning date. Data sheet also reports 8 MW IT. |
| 8.4 MW Unspecified power | Inzai 1 facility Operational · cumulative | 2019-06-11 | Conflicting claim ↗ Excluded from capacity totals. As-of date is announcement publication. Describes January 2011 completion as an 8.4 MW facility without explicitly naming the power basis in that sentence. Differs from current 8 MW IT claim; do not add or select without reconciliation. |
| 8 MW IT load | Historical KVH TDC2 first facility in Inzai Under Construction · cumulative | 2010-05-13 | Reported claim ↗ Excluded from capacity totals. Historical article publication date; design capacity during construction, not additional present-day capacity. Association with Inzai 1 is supported by matching first-building history and specifications. |
Industry report describes construction and a first-phase launch expected by February 2011; this is a planned milestone, not proof of opening that month.
Supporting source ↗Colt's 2019 retrospective states completion in January 2011. A 2016 Colt release separately places the existing facility's operating start in 2011.
