This poster was made to promote the roman porno flick Danchizuma: Okasareta hada, known in English as Apartment Wife: Violated Skin, eighteenth entry in the Apartment Wife series launched by Nikkatsu Corporation in 1971. Erina Miyai stars again, and we can’t imagine there are many surprises eighteen entries into the series, but we couldn’t find a copy so all you get is the poster. And the promo photo below. Danchizuma: Okasareta hada premiered in Japan today in 1977.
Miyai's indoor escapades continue in installment eighteen of Nikkatsu's popular series.
