The master craftsman Kunio Katada shows a new plastic nose flute on his blog, with the date 2011. I do not read Japanese - I use Google translation - and think I understood the flute is called "Hana Adachi" (who is a manga character from Flunk Punk Rumble), but I understood not much more.
The instrument looks very similar to the ones that are produced by Mr. Katada, so I suppose it is a prototype made by him. Is he going to mass-produce it ? I sent him a e-mail with some questions, and wait for the answers, but if a japanese reader can explain us what's happening, he would be welcome :)
