Born in 1936 in Tokyo, Japan, Keiichi Tanaami is an influential pop artist of postwar Japan. Tanaami took a keen interest in drawing at a very young age and often spent time in cartoonist Kazushi Hara's studio. He studied at Musashino Art University, earning a Special Selection recognition with a major design and illustration group. Since the mid 1960s, he became increasingly interested in psychedelic culture, Acid Music, and Pop Art, in particular Andy Warhol's work. In 1968, his award-winning antiwar poster "No More War" and his album artwork for the Monkees and Jefferson Airplane became a major impetus for the movement of psychedelic and pop art in Japan. In 1975, he became the first Art Director of Playboy (Japanese Edition), and in 1991 he started to teach at Kyoto University of Art and Design, where he is currently a chairperson of a Faculty of Information Design.
