Continuing with the provincial samurai mon, we have this simple depiction of a knot.(KJ:7)

Agemaki Knot

This is not just any knot, however. This knot is called “agemaki” (総角) and auspiciously symbolizes the four directions. It is hung above sumo rings, and was used on samurai armor both for decoration and as a structural component.(Samurai Weapons) For these reasons and its graphical simplicity, it makes a lot of sense as a samurai mon. Slightly more stylized depictions continue to be used in mon today,(Kamon Composition Maker) albeit rarely.

Less relevantly, it names a similar-looking historical (but later) hairstyle and type of dance in kabuki. Nowadays, they are used to decorate cars in Japan’s “VIP style”.(Diamond Zeus)
