Geography
Shikokuchūō is located in eastern Ehime Prefecture, with the Hoō Mountains to the south and the Gulf of Hiuchi of the Seto Inland Sea to the north. Because the plains are narrow, a local wind called "Yamaji" blows down from the mountains toward the sea. To the south of the Hoō Mountains, the Douzan River, one of the Yoshino River's tributaries, flows eastward, and further south are the Shikoku Mountains, which forms the border with Kōchi Prefecture. The Japan Median Tectonic Line runs east-west along the foot of the Hoō Mountains.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Shikokuchūō”, the useful work is to connect “city in Ehime Prefecture, Japan” to the records capable of establishing context and consequence.
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 26, 2026. The linked authority identifier is Q838666. The Library of Congress control number is n2017002664. Authority coordinates are 33.981, 133.549. 1 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2022.
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.
