Ushio Shinohara (nicknamed "Gyu-chan"), is a Japanese Neo-Dadaist artist who has lived and worked in the United States since 1969. His parents, a tanka poet and Japanese painter, instilled in him a love for artists such as Cézanne, Van Gogh and Gauguin.

Known for his boxing paintings, which are artifacts of his performances, Ushio works in several mediums including painting, printmaking, drawing and sculpture. His bright and frequently oversized work has exhibited at prestigious institutions internationally, including the Hara Museum of Contemporary Art; Centre Georges Pompidou; the Guggenheim Museum, New York; the Japan Society, New York; the National Museum of Modern Art, Tokyo; Leo Castelli Gallery; the Museum of Contemporary Art, Los Angeles; the Metropolitan Museum of Art, Seoul; and soon at the Dallas Museum of Art and the Tate Modern, among others.

Ushio and his wife of 42 years, Noriko, are most recently known from the Academy Award-nominated documentary Cutie and the Boxer. This documentary explores the history of the couple's often tumultuous marriage and their lives as artists.
