What is Butoh? 

Butoh, 舞踏, originally called Ankoku Butoh (Dance of Darkness) conceived in Japan during the late 50’s and early 60’s, during the social turmoil after the war sought to find an expression through dance. Rather than aspiring to an aesthetic ideal, the dance attempts to expose the joys and sorrows of life, exploring the most fundamental elements of physical and psychological existence. It goes beyond the confines of specific cultures and aims for universal expression that touches the soul of humanity. It also crosses the boundaries between dance and theatre, creating a unique form of expression that engages, moves and intrigues.
