This is a "netsuke," a small sculpted figure of a Karasu Tengu riding on something resembling a peach. Netsuke were used in the Edo period as fasteners to prevent items like inro (personal seals containers) and tobacco pouches from falling off the obi (sash). They were practical tools, but also "worldly items" used for ornamentation and to display one's refined taste. There are various types of netsuke, with "katabori netsuke," which are three-dimensional carvings of animals, people, and objects, being the most popular form. Today, they are sometimes used as straps for mobile phones or as decorations for bags. Thank you for viewing.
