Kōchi Castle

Kochi Castle is an unusually legible original-keep site: the keep, palace-related structures and compact hilltop plan still let visitors understand castle administration and defense together.

History

What historically stood here

The Japan Castle Foundation records 高知城 as a 平山城 site in 高知市, with the founding label 慶長6年(1601). The listed builder or associated clan is 山内一豊; principal lords are 山内氏.

The site’s history spans Edo period, Yamauchi clan, modern preservation.

Source and correction context

Identity, list membership, Foundation list number, municipality, basic classification and cultural-property notes are source-verified. Site-level visitor details require additional review unless this record is publishable. Foundation numbers are official list identifiers, not rankings. Coordinates use the Foundation-linked position-data KML and should be treated as visitor-planning coordinates rather than archaeological survey points.
