Yoshihiro Katō (1936-2018) was an artist and one of the founding members, along with Shinichi Iwata, of the avant-garde arts group Zero Jigen (Zero Dimension) in the early 1960s. Beginning with Haitsukubari kōshin (Crawling Procession), staged in January 1963 in the Sakae district of Nagoya, over a long period of time they executed an extraordinary number of performances known as “Rituals” in Tokyo and elsewhere.
