This is a shakuhachi (Japanese bamboo flute) "Kocho (Butterfly), composite bamboo, 1 shaku 6 sun, 5 holes" made by Wada Gakki. There are no cracks or splits, and the overall condition is good. The joint was slightly loose, so it has been repaired with aluminum tape, and there are no air leaks. There are faint scratches on the metal bands that the previous owner used as markings, but they are not noticeable (images 13 and 14). Composite bamboo is made by thinly splitting high-quality bamboo lengthwise and gluing it together, making it possible to produce a tone similar to that of a real bamboo flute. It is harder than bamboo and, like a wooden flute, it is almost impossible for it to crack or split.
