I study with this guy. Biased maybe. But really one of the best Shakuhachi Tradition upholders. With just about the most dynamic breathe you will find, which is a deeply relevant aspect. One person, (name forgotten, my apologies) made a statement i enjoyed and will paraphrase here. Kurahashi Sensei is the Kung Fu master of Shakuhachi. Said in reference of his dynamism, power and fine control, with the subtlest sense for truly elegant sound. Another relevant aspect. nuff said.
