Second Generation Takeyo Ebinuma, marked 1 shaku 5 sun tube. Cap is size 5. The black lacquer exterior is also very beautiful. I met Master Takeyo Ebinuma in my 30s, and I have used this shakuhachi for over 30 years, but I am selling it because I am ending my performance activities. This is not an antique, but a fully functional instrument that has been used in performance activities for over 30 years. I have used it with care, so I would like someone who plays the shakuhachi to use it. There are no scratches, but there is some age-related soiling (this is not an antique, so I think it's the natural level of soiling for a shakuhachi). A size 5 cap is included. The case is separate.
