Ko is one of the best known and acclaimed Butoh artists in the world and is recognised in Japan as a leading inheritor of Hijikata's original vision of Butoh. He studied with Hijikata in 1968, briefly 'giving up' dance to become a "Yamabushi" mountain monk, back into society he founded the Butoh-Group Dairakudakan together with Ushio Amagatsu, Akaji Maro and others. 1974 he created the Butoh-magazine Hageshii Kisetsu (Violent Season) and founded a female Butoh-Company Ariadone with Carlotta Ikeda, and for which he did many choreographies. Two years later he founded a similar only-male Butoh-group: Sebi.
