In the Realm of the Senses
was a Japanese film director known for his "Roman Porno" films, including three critically respected films known as the "Showa trilogy": "A Woman Called Sada Abe" ("aka" "Sada Abe: Docu-Drama") (1975), "Watcher in the Attic" (1976), and "" (1977), all three starring Nikkatsu "Roman porno" queen Junko Miyashita. The first film in this trilogy recounted the story of Sada Abe a year before Nagisa Oshima's internationally released "In the Realm of the Senses" (1976), which told the same story. Though at the time he was working, his career was overshadowed by directors such as Tatsumi Kumashiro and Chūsei Sone, many critics today judge Tanaka the best of Nikkatsu's "Roman porno" directors.
