Born in Kawasaki, Japan, 1946; died in 2025. He moved to the United States in the 1970s and worked in Los Angeles and New York, and from the 1980s onward developed his activity internationally, mainly through performance. Using "bread" — a material obtainable anywhere in the world — Orimoto subtly transformed places and situations through simple, improvisational acts. As both a staple food and a metaphor, bread functions as a widely shared material that invites a multiplicity of interpretations and imaginations within his actions, drawing critical attention across cultures and national boundaries. It is also significant that, while seemingly an idea anyone might conceive, these acts had never been realized by others, which contributed to making the series emblematic of Orimoto's practice. From the 1990s to 2017, he created an impressive number of works collaborating with his mother Odai, many of them arising from the situation of spending time together while he was caring for her Alzheimer's condition. Solo exhibitions include Hara Museum of Contemporary Art (Tokyo, 2000), Museum of Art Fort Lauderdale, Ikon Gallery (Birmingham) and Museu de Arte de São Paulo (MASP). He took part in the 16th and 18th São Paulo Biennials (1981, 1985), the 1st Havana Biennial (1984), the 8th Biennale of Sydney (1986) and the Yokohama Triennale (2001).
