A kamon is the emblem of a Japanese family. Samurai families put theirs on banners, roof tiles and armour, so the same design often marks the castle a family held.
This page lists 26 crests that Wikidata records for families connected to 33 of the castles in this database. Every crest links to the castle pages of the families that used it. Where a family held more than one castle, all of them are listed.
Crest images come from Wikimedia Commons; the licence and author are shown under each one. The family-to-castle links come from Wikidata, retrieved 2026-08-22. A family missing from this page means Wikidata holds no crest image for it — not that the family had no crest.
