Mr. Tetsuyuki Sudare is the owner of the online shop Temiruya, where you can order the clay nose flutes made by the potter-craftsman Hiroaki Sasaki. But Tetsuyuki Sudare is also a very fine nose flute player! In this fresh video, he whistles a tune with a very clear and precise sound... Beautiful! The video is a part of The Story behind the Confidential History of the Nose Flute by the NHK (Japanese TV and radio channels).
