Kokū Nishimura (西村 虚空, Nishimura Kokū, 1915 – June 2002) was a master shakuhachi player, teacher, and craftsman.
The early 20th century saw a revival of the shakuhachi as a secular instrument for ensembles. Amateur shakuhachi flautists formed secular orchestras. Nishimura, however, played an antiquated shakuhachi with no plaster added to the bore. He also favoured long instruments. He decided to call this flute style kyotaku in order to differentiate it from the shorter, modern shakuhachi tuned to D minor pentatonic. The name kyotaku comes from the legend of the foundation of the Fuke sect described in Kyotaku denki kokuji kai.
Nishimura's son, Koryū, continued the study and teaching of kyotaku in Kumamoto.
