I think I've been on that "mountain" in Kyoto, which is actually a hill, the climbing of which is very strenuous exercise, even though there are steps all the way to the top. On the top, there is a shrine and monks doing their thing. It was more a mystical experience than a musical one. I share the doubts that bamboo on that hill would be any different from bamboo on some other nearby hill that is subjected to the same weather. But then, I'm an agnostic in all things. If folks are selling their Kansui's in order to obtain the new model, I may be a buyer of a Kansui.
