Summary

In its release of 5 October 2026 IIJ states that the large-capacity lithium-ion batteries installed at its IIJ Matsue Data Center Park are operated as backup power for the data-centre facilities, and commits about 1,000 kWh of that stored power to Matsue City's evacuation shelters under a disaster power-supply agreement concluded that day. This is the operator's present-tense description of the existing campus in service on 5 October 2026. It establishes no new building, phase, capacity, utilisation or construction; the planned disaster drills are future work. evidence

Names Matsue Data Center Park and associates the updated campus photograph. It separates Site 1, including its system-module building, from adjacent Site 2; opening dates are stated only to month precision. evidence

Internet Initiative Japan · publication date not stated

Named operator service page associates the aerial image with Matsue DCP and describes existing colocation, housing and service infrastructure. Its receiving-capacity narrative and table use different units; neither is selected as IT load. evidence

Internet Initiative Japan · publication date not stated

Photograph linked by the named operator profile shows a broad main roof, western utility block, retained eastern container row, roadside parking and a curved perimeter. Used to match the northern campus property to georeferenced imagery. evidence

Internet Initiative Japan · publication date not stated

Photograph linked by the named operator service page shows two adjacent container-array properties beside the curved road. The northern central spine and retained eastern row, southern array and surrounding terrain corroborate the campus identity. Acquisition date is unknown. evidence

Prefecture identifies the original IIJ location at Hokuryo-cho 57 and 58 in Soft Business Park Shimane. The page describes the August 26, 2010 signing and planned April 2011 operation; it supplies historical property context, not current status or a current legal boundary. evidence

Returned EPSG:4326 extent and 1600 by 1200 dimensions support the pixel-center calculation. The image and JSON response use separate requests with identical explicit parameters; no surveyed ground accuracy follows. 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

Location details

Coordinates: 35.49420, 133.06360
Geometry licence: all-rights-reserved
Use scope: Campus locator
Scope class: operator_named_campus_matched_to_georeferenced_imagery
Authority: Compiled location reference
Source entity: Campus
Method: manual_named_operator_aerial_match_to_esri_wgs84_imagery
Derivation: georeferenced_source_map
Precision scope: Approximate analyst-selected point within the identified northern Matsue DCP property, used only as a campus marker and rounded to four decimals. It is not an operator-published pin, surveyed centroid, parcel boundary, building footprint or individual phase marker.
Horizontal uncertainty: Not reported
Image acquisition date and absolute geolocation accuracy are unestablished. Roof parallax, historical building changes and manual identification introduce unquantified uncertainty; image resolution and decimal places are not ground accuracy.
Geometry evidence: 9162792b

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.
