This is a Shinobue flute by Shishida-ryu Takusui! This Shinobue is a Shishida-ryu Takusui flute crafted by the second-generation flute maker, Chuichi Ito of Ito Takekanki Seisakusho, who inherited the Shishida-ryu style from the late Edo period. Produced in the late Showa era, this flute is about fifty years old. The bamboo is well-dried and has a beautiful, natural color with a refined, mellow tone. It is a fine instrument. Please consider purchasing it. Thank you very much!!
