Some 9 months ago, we were wondering (in this post) if a japanese new plastic nose flute was somehow on the bench. We had found its pictures on Mr. katada's blog.
There is new info about this product, which is apparently produced on a regular basis now. On his Facebook page, Mr. Mosurin just displayed a picture of those plastic hanabue, and confirmed they are a beginner model, with dimensions especially adapted to women and children physiognomy. Sensei Mosurin uses them in schools to teach the art of the nose flute playing. We are impatient to try them.
