Yayoi Kusama is a Japanese contemporary artist who works primarily in sculpture and installation, and is also active in painting, performance, video art, fashion, poetry, fiction, and other arts. Her 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. She has been acknowledged as one of the most important living artists to come out of Japan, the world's top-selling female artist, and the world's most successful living artist. Her work influenced that of her contemporaries, including Andy Warhol and Claes Oldenburg.

Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving and modelling, in stone, metal, ceramics, wood and other materials but, since Modernism, there has been almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or moulded or cast.
