Operational last observed as of 2026-08-07 · Authoritative status update

KDDI Corporation · published 2026-01-22

January operator release labels this image as Osaka Sakai Data Center exterior. The KDDI-branded block, roof spine, offices and adjacent factory corridor support location matching. Photograph acquisition day is unestablished. evidence

KDDI Corporation · publication date not stated

Operator interview names and labels the converted factory and its photograph. Historical identity and operating context only; no current capacity or completion of future development inferred. evidence

KDDI Corporation · published 2026-01-22

Another operator-labelled view of the same KDDI-branded block shows the long roof cooling spine, adjacent office bars, factory corridor and open strip. Used only for identity matching; acquisition day unknown. evidence

KDDI Corporation · publication date not stated

Firsthand acquisition adviser identifies the land/buildings of the former color-filter production facility within Green Front Sakai, about 33,000 square metres of site area and 57,000 square metres of floor area. Reports the transaction closed April 4, 2025. Areas distinguish the property; they are not converted to power. evidence

CBRE Japan · published 2025-05-12

KDDI identifies its purchased former Sharp Sakai property and the Osaka Sakai Data Center development. Historical transaction identity only; future operation in this source is not the selected current status. evidence

KDDI Corporation · published 2025-04-04

Seller states the sale contract and property transfer/handover occurred April 4, 2025. The acquired land and buildings are in Sakai-ku; no surveyed boundary is supplied. Historical acquisition fact, not an independent current legal-title check. evidence

Sharp Corporation · published 2025-04-04

Separate SoftBank transaction covers about 450,000 square metres of land and 840,000 square metres of buildings. This identity context must not be merged with KDDI former color-filter property or treated as fresh SoftBank operations. evidence

SoftBank Corp. · published 2025-03-14

Returned WGS84 extent and 1400 by 1200 dimensions reproduce the selected pixel-center coordinate. The returned extent differs from the requested box to fit the aspect ratio. Direct image request and the JSON-returned image have identical SHA-256 hashes. evidence

Esri World Imagery · publication date not stated

Service metadata supplies attribution. Generic advertised imagery resolution does not bound accuracy at this campus. evidence

Esri World Imagery · publication date not stated

Export JSON supplies the actual returned map extent, dimensions and scale. Esri warns that extent can change to fit the aspect ratio, so the calculation uses the returned extent and explicitly requested image spatial reference. evidence

Esri · publication date not stated

Historical context: April 30 release confirms trial provision of Gemini on GDC began March 27 at named Osaka Sakai facility. Full commercial service targets 2027. This clarifies the service referred to by July 28 current assertion; April is not selected as fresh status. evidence

Location details

Coordinates: 34.59710, 135.43970
Geometry licence: all-rights-reserved
Use scope: Campus locator
Scope class: operator_named_converted_factory_property
Authority: Compiled location reference
Source entity: Campus
Method: manual_named_operator_exterior_match_to_esri_wgs84_imagery
Derivation: georeferenced_source_map
Precision scope: Approximate analyst-selected point at the KDDI-identified converted factory property within the historical Green Front Sakai complex, rounded to four decimals and used only as a campus locator. It is not an operator-published pin, surveyed centroid, parcel boundary, occupied server-room footprint or marker for the whole historical Sharp complex.
Horizontal uncertainty: Not reported
Imagery acquisition date and absolute positional accuracy are unestablished. Roof parallax, historical changes and manual matching introduce unquantified uncertainty. Pixel resolution and decimal places are not measured ground accuracy.
Geometry evidence: 5d4f853a

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.
