Japanese castles classified by preservation status and architectural type.
Data on this site comes from Wikidata, Wikimedia Commons, OpenStreetMap, the National Land Numerical Information service (MLIT), the Agency for Cultural Affairs national database of designated cultural properties, and the official site of each castle. Checked 2026-08-22.
A blank or missing line means we found no record in those sources — not that the castle lacks the thing. Admission fees, opening hours and access change without notice; please confirm with the official site before travelling.
