Thank you for viewing. I am a gagaku (Japanese court music) hichiriki player with over 50 years of experience. This reed is made from high-quality reeds from Udono, with an outer diameter of 11.5-12mm. They are carefully selected and dried in the shade for about a year and a half, and then smoked over an irori (sunken hearth) for over 10 years. This results in reeds that are both durable and of the highest quality, and it's no exaggeration to say they are top-of-the-line. The finishing touches, including the hat, seme (binding), and washi paper, are also carefully selected. While preferences for thickness vary, this reed is designed to fit any hichiriki, whether plastic or genuine. It is said that the most important aspect of the hichiriki is not volume, but tone. To produce a good tone, you must breathe deeply and blow with force. The price is a bit high, but please rest assured that we will handle returns and exchanges. 《*Please note that you will be responsible for the shipping costs for returns and exchanges.*》 Also, please refer to past reviews of my reeds to gain a better understanding. I am confident that you will be satisfied with these reeds, so please consider them.
