Yoyogi (代々木) family name, Tadashi (忠) first name, (1938-)
Tadashi Yoyogi appears to have begun his career as a director of pink films in about 1963. He ranks among the pioneers of the pink film industry. In the 1970s, he was also the producer of films directed by Shinya Yamamoto and worked for Nikkatsu in the late 1970s. He continued his work into the 1980s when pink films waned and adult videos (AV) began to dominate. In the 1980s, he became well-known as an AV director. Although his work did not exclusively feature SM, in 1983 he can be heard off-camera interviewing actress Mami Fujii in a two-part video called Orgasm which featured kinbakushi Eikichi Osada. He is credited as the supervising editor for these videos which were produced by Athena and distributed by Mimizuku Video.
