Shugetu Kato, a kinko-ryu shakuhachi performer and pipe maker in the Meiji period (?) I think its made.
The time of pipe making is unknown, but it is a good-looking bamboo material that has changed to a candy color, and it can be assumed that it has been carefully blown in from the reduction of the finger holes.
The lacquer in the tube shone like a mirror without peeling off, and it must have been exceptionally well maintained.
The cracks near the back hole are stopped by cherry blossom skin and there is no breath leakage.
