Switching to sculpture and installation as her primary mediums,
Kusama became a fixture of the New York avant-garde,
having her works exhibited alongside the likes of Andy Warhol, Claes Oldenburg and George Segal during the early 1960s,
where she became associated with the pop art movement.
Embracing the rise of the hippie counterculture of the late 1960s,
Kusama came to public attention when she organized a series of happenings in which naked participants were painted with brightly colored polka dots.

Frustrated with this distinctly Japanese style, she became interested in the European and American avant-garde,
staging several solo exhibitions of her paintings in Matsumoto and Tokyo during the 1950s.
In 1957, she moved to the United States,
settling down in New York City where she produced a series of paintings influenced by the abstract expressionist movement.[浮云][浮云][浮云][浮云][浮云][浮云][浮云][浮云]

Although largely forgotten after departing the New York art scene in the early 1970s,
Kusama is now acknowledged as one of the most important living artists to come out of Japan, and an important voice of the avant-garde.
Born in Matsumoto, Nagano into an upper-middle-class family of seedling merchants,
Kusama started creating art at an early age, going on to study Nihonga painting in Kyoto in 1948.
