Genpei Akasegawa was a pseudonym of Japanese artist Katsuhiko Akasegawa, born March 27, 1937 – October 26, 2014 in Yokohama. He used another pseudonym, Katsuhiko Otsuji, for literary works. A member of the influential artist groups Neo-Dada Organizers and Hi-Red Center, Akasegawa went on to maintain a multi-disciplinary practice throughout his career as an individual artist. He has had retrospective exhibitions at the Hiroshima City Museum of Contemporary Art, Chiba City Museum, and Oita City Museum. His work is in the permanent collection at Museum of Modern Art in New York. Artist Nam June Paik has described Akasegawa as “one of those unexportable geniuses of Japan.”
