If you need an instrument please consider my Bell shakuhachi
Authentic shakuhachi are expensive because they take a great deal of time and effort to make. The time and effort is greatly magnified when making quality jinashi shakuhachi, especially nobé or “whole” shakuahchi which do not have joints.
Harvesting and processing root-end Japanese madaké bamboo is very hard work and it’s difficult to come by. Because bamboo is a natural material many pieces do not end up being suitable, however, one often only learns this after years of waiting. Out of the shakuhachi that are functional even a smaller amount are of a truly high quality.
In the case of jiari shakuhachi there are more choices regarding bamboo due to be able to adjust the length using joints and by being able to use a wider range of bore diameters since the bore is filled with plaster paste. However, a lot of work goes into jiari and usually fine tuning as well.
