Shakuhachi Making Workshop with John Kaizan Neptune

John Kaizan Neptune is a shakuhachi master player and a master maker based in Chiba, Japan. John Kaizan’s analytical approach to shaping the bore has enabled him to fine-tune individual notes across the three octaves range, thus creating a well balanced, precisely tuned instruments with projection comparable to western classical instruments. In recent years, he has expanded his understanding to also produce extraordinary jinashi shakuhachi.

You can hear John Kaizan’s flutes on stage in the hands of Japanese and international masters such as Kifu Mitsuhashi, Kuroda Reison, James Nyoraku Schlefer, Kakizakai Kaoru, Adrian Freedman and many others.
Outside of being a shakuhachi maker, John Kaizan Neptune is an extraordinary shakuhachi player, pioneer of the jazz shakuhachi, and a composer.

Over three days, you will be cutting, drilling and filing bamboo under the supervision of a master maker to make a jinashi shakuhachi. John Kaizan Neptune will show you and help you how to precisely shape the bore and fix the problems your instrument may have. Under Kaizan’s guidance, you can make a jinashi shakuhachi from start to finish (as much as time permits), or you can bring a semi-finished shakuhachi in to the workshop to finish it under his supervision.
