Skin surface diameter: 37 cm, body height: 21 cm. Although there is some wear and tear, it is generally a beautiful item and a good-sounding shime-daiko. Originally, a 5-sun body (body height 15 cm) was used, but the tips of the bolts were hitting the iron ring on the opposite side of the skin, making it impossible to tighten them strongly. Therefore, when the body was replaced with a 7-sun body (body height 21 cm), a deep, high-pitched sound began to be produced. Since it has not yet been tightened to its maximum extent, I believe it will become even more active in performances and other activities as a shime-daiko.
