Kōchi Castle
高知城
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 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.
