Tadanori Yokoo was born in 1936 in Nishiwaki, a small city in Hyōgo prefecture west of Kobe. He started at the Kobe Shimbun newspaper at twenty as an illustrator and layout artist, moved to Tokyo in 1960 and joined the Nippon Design Center — the same founding studio that launched Yusaku Kamekura and Ikko Tanaka.
He left in 1964 to work independently. Over the next ten years he made himself the defining Japanese poster designer of the decade through sustained commissions for the avant-garde theatre companies Tenjō Sajiki (Shūji Terayama) and Hakutōbō (Tatsumi Hijikata), and through a stream of provocative self-portrait pieces. In 1972 the Museum of Modern Art in New York gave him a solo exhibition — the first ever awarded to a Japanese graphic designer — and the international recognition that followed never really stopped.
In 1981 Yokoo announced he was leaving graphic design to concentrate on painting and fine art. He has largely held to that ever since, though the line between his design and fine-art practice has always been porous. The Tadanori Yokoo Museum of Contemporary Art opened in Kobe in 2012. He was awarded the Praemium Imperiale in 2023.
