This rare miniature nobori bata (festival banner), dating from 1850–1900, is one of a set of three meticulously crafted for the annual Boys' Day celebration. Measuring 8 inches by 29 inches (20 cm x 74 cm), the banner is made from high-quality chirimen silk—a crepe fabric spun tightly to produce a distinctive, pebbled texture.

The banner features a striking sumi-e (ink wash) illustration of a warrior on horseback, likely representing the legendary young general Yoshitsune. A hero of the 12th-century Genpei Wars, Yoshitsune is depicted with his signature bow and arrows, mounted on a horse rendered with fine calligraphic lines. The upper portion of the banner is accented with two bold indigo horizontal stripes, while the left edge features six white mounting tabs reinforced with "X" stitching. A single red tassel hangs from the bottom corner, adding a small pop of ceremonial color. These banners were traditionally displayed in the home's tokonoma (alcove) alongside warrior dolls to inspire bravery and honor in young boys.
