This is the Shishida-ryu Shinobue Takusui. It's a 6-hon choshi, 6-hole, tenchi tou-maki (top and bottom wrapped with rattan), natural color finish. This is a Shishida-ryu Shinobue Takusui made by the second-generation flute maker, Chuichi Ito of Ito Chiku Kangakki Seisakusho, who inherited the legacy of the flute maker Shishida from the late Edo period. It was made in the late Showa era, over 40 years ago. The bamboo is well-dried, and the tone and sound quality are excellent, making it a well-finished instrument. We highly recommend it. Please be careful of temperature changes and humidity. We recommend occasionally wiping it lightly with plant-based oil.
