Traversing the world between art and design, Tadanori Yokoo's work has a very personal nature and often reflects his own interests. He began working as a designer during the late 1960's and his work often resembles a collage style that was quite the opposite of the modernist movement. Interested in mysticism, psychedelia and the Indian culture his work is often associated with the 1960s pop culture. He has repeated several motifs throughout his work including the rising sun and waterfalls. In 1998 a large scale exhibition of his posters was held in Japan, the 40,000 people that crowded the exhibition during its thirteen-day event were a testament to his popularity.
