The Kono Clan crest is the old crest of Ōyamazumi Shrine, distinguished by its three wavy lines which symbolize the sea. This design reflects the clan's deep historical and geographical ties.
A simplified version of this crest, featuring three straight lines, is commonly seen on many of the Shikoku pilgrimage temples within the Iyo Domain. The prominence of this crest on religious sites highlights the Kono clan's significant historical patronage of religion throughout the region.
