A black lacquered Jingasa, a type of lightweight military headgear used by samurai and their retainers during the Edo period of Japan (1603–1868). This particular example dates to the late Edo period, in the 19th century. Jingasa were functional items, designed for basic protection during military travel or ceremonial processions, and were often constructed from wood or metal and finished with layers of urushi lacquer for durability and weather resistance.

This Jingasa is distinguished by the presence of two motifs: a sagarifuji (hanging wisteria) family crest and a Genbu turtle. The sagarifuji is a stylized representation of the wisteria plant, used as a family crest (mon) by several Japanese clans, most notably the Fujiwara. Family crests served to identify the wearer’s lineage or allegiance, particularly in contexts where armor and uniformity were prevalent.

The Genbu motif represents a black turtle entwined with a snake, which is a symbol imported from Chinese cosmology. In Japanese tradition, Genbu is one of the four directional guardian deities and is associated with the north and with longevity and protection. The combination of a family crest and the Genbu symbol on a Jingasa is uncommon and potentially indicates a specific lineage, a particular role within a feudal household, or a special function such as ritual or protective service.
