 Thus, although Dan Oniroku's works are generally not considered a high-brow literature but a soft pornography, his influence on certain works of Japanese popular fiction and film industry is considerable.Moreover, Dan not only contributed to the Japanese pink film industry but also to the S&M publications, as he established another S&M magazine, "SM King" in 1972 (active till 1974).In the early 1990s, having by then written over two hundred S/M novels, Dan ceased writing and embarked on an ultimately unsuccessful business venture.
