Maru ni Chikiri Trucker Hat

The chikiri mon (family crest) is associated with a tool used in weaving called 'chikiri' or 'tatemakigu', which is a rod. The chikiri crest depicts the state of the warp threads being wrapped around this rod, symbolizing a strong connection. It is also related to the notching used to join wooden members together. The design is believed to have originated in the Fujiwara period and is seen in artworks such as 'Nenchū Gyōji Emaki' and 'Kasuga Gongen Genki Emaki', eventually evolving into a family crest (according to 'Kamon no Jiten' by Takasawa et al.).
