Banner (Sashimono)
Banners (sashimono) were historically worn by soldiers in feudal Japan for identification during battle. Their L-shaped poles were attached to the back of the cuirass in a variety of ways and such banners, resembling small flags, bore family crests or other identifying symbols. The central crest of interlocked circles (wa-chigai) was used throughout Japanese history by several families, most prominently so by the Wakisaka (脇坂), who were land-holding feudal lords (daimyō) until the abolition of the feudal system in 1868.
