The Odaiko is a large Japanese barrel-shaped drum. Taut skins are stretched across each end of the body, though usually only one end is struck. It sometimes rests on a stand and is played with two sticks whose ends may be padded. The odaiko is used as a bass drum in many styles of Japanese music, especially in the theater and for some types of festive dances.
