A tube-shaped container for a nō-kan (Noh flute). On stage, it is attached to the player's right hip. Pieces of traditional Japanese paper and cloth are laminated in a wooden mould to form a tube, whose outside is lacquered and hardened. Many are of high artistic value, decorated with beautiful makie ornamentation. A ring is attached at the middle of the tube, and a braided cord attached to it. In some schools, the cord is tied around the strings of the hakama trousers to prevent it from falling. Some tubes have the bottom pierced with a hole and fitted with beautiful metal parts.
