This miniature silk flag from Japan dates to the Taisho period (1912–1926). Measuring 15 inches in width by 40 inches in height (38 cm by 102 cm), this textile was an integral component of a May 5 Boys' Day (Tango no Sekku) "warrior" display. Traditionally arranged in the tokonoma (alcove) of a Japanese home alongside Musha Ningyō (warrior dolls), such flags were used to honor the virtues of bravery and the samurai spirit. The piece is in very good condition, showing only a few subtle moth holes and one small stain consistent with its age.

The flag is rendered in a monochromatic sumi-e style on white silk, featuring a dynamic scene of a samurai warrior on horseback. The armored figure is depicted charging through churning waves, a reference to heroic military feats of the past. Arrows fly through the dark, misty air around the warrior, who raises a sword high in a gesture of defiance or command. A small banner on the warrior's back displays a diamond-shaped mon (family crest). The flag retains its original brown fabric attachment loops along the top and right edges, intended for mounting on a miniature pole.
