Thank you for viewing. This is a Fue (bamboo flute) made by Aizan Yamada, a flute maker, using genuine "hon-susudake" (smoked bamboo) and tuned to 8 honchoshi (a specific key), for playing uta (songs). *I apologize that the maker's mark is difficult to see. This is a valuable hon-susudake flute that I inherited. *The bamboo used was from the ceiling of an old folk house, and over 100 years of exposure to the smoke from the irori (sunken hearth) has given it a unique and beautiful amber color. The flute also has marks from nails used at the time, and I think it's a piece with a lot of character. (The black parts are traces of soot.) Being hon-susudake, this is a difficult-to-obtain flute. The condition is quite good, but it is a used item, so please understand this and consider purchasing it if you will cherish it. *It will be cleaned, waterproofed, and packaged with shock-absorbing materials before shipping. It can be purchased as part of a set or individually. I will also discount the price as much as possible! If you are interested, please feel free to comment. Thank you for your consideration.
