Daimyō, provincial governors, and other high-ranking samurai carried swords mounted either as katana or tachi types. However, they were not able to wear these long swords when travelling in a palanquin (covered litter), when their swords accompanied them in cases carried by attendants.
This sword case is made of lacquered wood with gold makie and shell inlay with an all-over design of a grapevine. The outer leather case has the mon (family crest) of the owner in gold leaf.
