… Netsuke, a small carved object made to wear with traditional Japanese kimono.
A netsuke is a small sculptural object which has gradually developed in Japan over a period of more than three hundred years. Netsuke(singular and plural) initially served both functional and aesthetic purposes. The traditional form of Japanese dress, the kimono, had no pockets. Women would tuck small personal items into their sleeves, but men suspended their tobacco pouches, pipes, purses, writing implements, and other items of daily use on a silk cord passed behind their obi (sash). These hanging objects are called sagemono. The netsuke was attached to the other end of the cord preventing the cord from slipping through the obi. A sliding bead (ojime) was strung on the cord between the netsuke and the sagemono to allow the opening and closing of the sagemono. Source – World of Netsuke.
