What we checked

• MEXT identifies RIKEN Center for Computational Science in Kobe, Hyogo as the installation location for the Fugaku supercomputer. (source) Suggest a correction
• MEXT records 9 March 2021 as the start of full shared use of Fugaku. This is a historical system milestone, not a current whole-facility operating check or an offer of available compute. (source) Suggest a correction

This record identifies the named Kobe host for Fugaku from MEXT's historical system-development account. Shared use beginning in 2021 is a system milestone, not a current whole-facility operating check, facility opening date or an offer of compute. The predecessor K computer and prospective successor are not merged into a current campus status. Facility operator and legal owner, precise coordinates, street address, capacity, power, cooling, planning and current eligibility or allocation remain unverified. RIKEN website material and links are excluded under the source-use assessment. One host account does not establish Japanese coverage or available compute.

Chips

• MEXT’s draft post-evaluation describes development of the A64FX CPU for Fugaku.
  Scope: Historical system-development account in the February2022 Information Committee draft, not a final evaluation, current hardware inventory, facility status or evidence of available compute. The selected paragraph is about the developed CPU; it does not supply an installation date. The February10 committee meeting date is not a hardware event date.. Stage: Stage not known. Basis: reported. Evidence: official source. Evidence date: not stated. source. Source version: not established. Source published: not stated; source updated: not stated; retrieved: not recorded; reviewed: 2026-11-01T02:38:26.395Z; evidence checked: 1 November 2026.

Inspect the limits of this source check

These notes describe a bounded inspection, not a whole planning-application audit. They do not count as recorded facility fields, prove that information does not exist elsewhere or refresh this record's check date.

• Grid connection, PUE, Water use, Coordinates: Not stated in the inspected source. Only the draft cover, project context and selected CPU-development paragraph were inspected for this proposal. No grid voltage/substation boundary, typed PUE result, water-use measurement or verified point/CRS was established there. Reported application power/performance figures are not admitted or treated as grid connection/capacity. No utility, environmental, planning or parcel audit or report-wide absence conclusion is claimed. Scope recorded 1 November 2026; inspected source context.
