This is a Shishida-ryu bamboo shinobue flute. It is a 7-hon choshi (key) with 7 holes, featuring a natural color finish with tenchi (top and bottom) rattan wrapping. This is a Shishida-ryu bamboo shinobue flute crafted by the second-generation flute maker, Chuichi Ito of 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 is well-dried, has taken on a natural color, and has developed a refined patina. The tone and sound quality are excellent, resulting in a wonderful instrument. Please be mindful of the temperature difference. I highly recommend this one!!
