Yes, she has great lung capacity, but part of the trick for the shakuhachi is the embouchure. The lips are only letting a tiny stream of air pass. The air in the lungs lasts longer that way.
The more I listen to the shamisan the more I see the origins of a lot of western music.. In today's standards I would compare it to free grunge(new name🤣) it's got that feel and every performance iv seen the emphasis is on skill loudness Fantastic
