PURPOSE: To provide a koto (Japanese harp) bridge which can be stood and set in an extremely stable contact state by three-point support to the koto body upper surface, is never shifted even by the vibration of a string in play to surely transmit it to the koto body, and provides excellent musical interval and tone color. CONSTITUTION: A paired leg part 2 which is forked ink two so that the bottom surfaces come into contact with the upper surface of a koto body B and a string support part 3 which has a mountain form having a string fitting groove 4 on the upper surface and is arranged on the upper part of the leg part 2 are integrally formed to form a koto bridge 1 having a prescribed width. One set point 11 is arranged and formed on the bottom surface of either one leg part 2 situated on the side of a string, and two set points 12, 13 on the bottom surface of the other leg part 2. The set points 11, 12, 13 are formed as protruding curved top parts, and at least one leg part 2 is formed so that either one side part is narrow in section, compared with the other side part.
