This is a Shishida-ryu shinobue bamboo flute crafted by the second-generation flute maker, Chuichi Ito of the Ito Takekanki Seisakusho, who inherited the Shishida-ryu style from the late Edo period! It was made in the late Showa era, over 40 years ago. The bamboo is well-dried, with a beautiful natural color and a rich, mellow sound, making it a fine instrument. Please be careful of temperature and humidity changes! Thank you for reading to the end. We sincerely hope you will consider this flute after carefully viewing the photos. Thank you very much.
