- Derivation
- association_converted_official_cadastral_reference_polygon
- Precision scope
- The company names the same cadastral parcel as its data-center site. The association-converted polygon is retained as a reference parcel, not promoted to an official campus boundary, surveyed building footprint, active Phase I work extent or substation boundary. The centroid is only a derived display anchor. The same-number four other-city-district parcels and the Tokyo corporate office are excluded.
- Horizontal uncertainty
Not reported
The source classifies this as graphically measured map data and provides no numeric parcel-specific horizontal uncertainty. CRS84 coordinates are retained, without claiming survey precision or exact datum-realization accuracy.

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.
Evidence
Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
