Kazuo Ohno
The work developed beginning in 1960 by Kazuo Ohno with Tatsumi Hijikata was the beginning of what now is regarded as "butoh". In Nourit Masson-Sékiné and Jean Viala's book "Shades of Darkness", Ohno is regarded as "the soul of butoh", while Hijikata is seen as "the architect of butoh". Hijikata and Ohno later developed their own styles of teaching. Students of each style went on to create different groups such as Sankai Juku, a Japanese dance troupe well known to fans in North America.
