Thank you for viewing. Purchased for 150,000 yen about five years ago from someone I have a connection with. The ko-tsuzumi is a framed drum with an hourglass-shaped body. This ko-tsuzumi is made of synthetic leather, which is not easily affected by temperature or humidity, making it easy to handle and store. The pitch and resonance of the sound can be adjusted by tightening or loosening the chigiri (cords) to change the tension of the leather. As an instrument that expresses a unique resonance and tempo, it is used in Kabuki, hayashi (musical accompaniment), and folk performances. The body is made of plastic, making it easy to handle, and it is also recommended for educational purposes in schools. Please purchase only if you understand that this is a used item. If you have any questions, please feel free to comment. We may be able to negotiate a price reduction depending on the intended use, so please feel free to consult with us. Thank you very much.
