Shakuhachi has traditionally been played almost exclusively by men in Japan, although this situation is rapidly changing. Many teachers of traditional shakuhachi music indicate that a majority of their students are women. The 2004 Big Apple Shakuhachi Festival in New York City hosted the first-ever concert of international women shakuhachi masters. This Festival was organized and produced by Ronnie Nyogetsu Reishin Seldin, who was the first full-time Shakuhachi master to teach in the Western Hemisphere. Nyogetsu also holds 2 Dai Shihan (Grand Master) Licenses, and has run KiSuiAn, the largest and most active Shakuhachi Dojo outside Japan, since 1975.
