This is a Shishida-ryu shinobue (bamboo flute) "Chikusui" crafted by the second-generation flute maker, Chuichi Ito, of the Ito Takekanki Seisakusho, who inherited the techniques of the late Edo period flute maker, Mr. Shishida. It was made in the late Showa era, over 40 years ago. The bamboo material is well-dried, and the top and bottom are wrapped with rattan, making it a fine instrument. Please be careful of temperature changes and high humidity. Thank you for viewing. We hope you will consider purchasing it.
