Why this record matters
The phrase “city in Tokyo, Japan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q208863. VIAF identifies the subject as 159452757. The Library of Congress control number is n81018279. Authority coordinates are 35.666, 139.316. 1 of 6 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 2021 and 2015.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
