Yayoi Kusama (草間 彌生 or 草間 弥生 Kusama Yayoi , born March 22, 1929 in Matsumoto, Nagano Prefecture) is a Japanese artist whose paintings, collages, soft sculptures, performance art and environmental installations all share an obsession with repetition, pattern, and accumulation. (She has described herself as an "obsessive artist".)
Kusama's work is based in Conceptual art and shows some attributes of feminism, minimalism,surrealism, Art Brut, pop art, and abstract expressionism, and is infused with autobiographical, psychological, and sexual content. Kusama is also a published novelist and poet, and has created notable work in film and fashion design. She has long struggled with mental illness.
