Akasen Tamanoi: Nukeraremasu AKA Street of Joy (1974) - Tatsumi Kumashiro

It's the evening before the day all brothels must be shut-down, according to the new law, in 1958. At the Kofukuya's (literally, the house that sells happiness), five prostitutes decide to celebrate the day. Erotism, drama, and comedy mix as each hour, and a different event passes, in which all the women's stories come to the surface.

Enjoyable foray into the sex industry of 1950s Tokyo. Although it is usually classed as erotica, Street of Joy is largely character-driven, with some nice performances. It is a gently reflective, almost nostalgic film, showing the liaisons of prostitutes and clients with compassion. It holds back from judging the central characters and focuses instead on their individual drives and passions. There is a strong sense of family among the girls in the house, and it is through their eyes we view numerous male clients. At times poignant, often amusing, the film depicts a day in the life of the house - from opening to closing time - on the eve of the day brothels are to be outlawed in Japan.

Kurobara shôten (1975) - Tatsumi Kumashiro

Tatsumi Kumashiro is one of the most accalimed pink film directors to emerge from Nikkatsu studio in the 70s. His films, though almost all erotic in nature, are often chosen by the respected Kinema Junpo as best films of the year.

Story outline translated from a Japanese source:
"Kurobara Shouten" (roughly translated as "the Ascension of Black Rose") tells the story of a porn film director Juzo (Shin Kishida of "Mandala"), who has a second profession of creating porn tapes (hilariously) by recording sound of animals in a zoo and in a dental clinic. He gets stuck in the middle of the production of his new film because the main actress, Meiko, wanted out since she is pregnant by the actor of the film. Later, Juzo accidentally records the sound of a sexually repressed traditional woman named Ikuyo ("Queen of SM" Naomi Tani of "Wife to Be Sacrificed" and the original "Flowers and Snakes") making out with the dentist. It turns out that Ikuyo is the mistress of a wealthy businessman, and she flirts with the dentist to satisfy her carnal needs. Juzo, disguised as a private detective, approaches Ikuyo and tries to persude/seduce/coerce her into being the new actress of his film.

Koibito-tachi wa nureta aka aka Twisted Path of Love aka Lovers Are Wet (1973) - Tatsumi Kumashiro

Quote:
In his Behind the Pink Curtain: The Complete History of Japanese Sex Cinema, Jasper Sharp writes that, like Woods are Wet and The World of Geisha (both 1973), Lovers Are Wet is one of Kumashiro's indictments of the hypocrisy of censorship.[3] As in these other films, Kumashiro uses the censors' tools purposely to ridicule the practice. In a scene in which a group of people play nude leapfrog on a beach, Kumashiro hides the actors' genitals by scratching the surface of the film, "creating a bizarre writhing spaghetti of lines."[3] Film historian Donald Richie pointed out that the Japanese censors had used this method on nude audience members in the film Woodstock (1970). While these non-erotic nudes passed unnoticed in countries without such censorship, Richie notes of the Japanese version, "When the film was projected the distant strolling couples consequently seemed girdled with fireworks. Though this called instant attention to what the censors were presumably attempting to hide, the letter of the law had been observed and this result satisfies all censors everywhere."
