Born in what is now part of Takatsuki, Osaka, Japan where his father was a soy sauce brewer, Ōya showed an early interest in social issues, and after dropping out of the University of Tokyo, he became involved in the Japan Fabian Society (a gradualist Socialist group). He was also active as a literary essayist and founded the Mass Communication Juku (マスコミ塾, literally the "Mass Communication Workshop"). His legacy includes the Oya Soichi Nonfiction Award, which recognizes the contributions of young journalists, and the Ōya Sōichi Library, a library that is the major archive in Japan collecting popular publications that most institutions ignore. Most of his literary works are included in the "Ōya Sōichi Zenshū" (大宅壮一全集) published by Sōyōsha (蒼洋社). He was praised "as an iconoclast and hailed for the 'heckling spirit' he had cultivated throughout his career," but he has also been criticized for his critical attitude towards new religions.
