On the subject of Japanese exploitation movies, Mondo Macabro have several interesting new or upcoming releases of 1970s pink or pinky violence movies from Nikkatsu Studios, including
Naked Rashomon and
The Sins of Sister Lucia, which seems to be a combination of nunsploitation and pinky violence in the style of School of the Holy Beast.
The Watcher in the Attic looks intriguing as well. Apparently based on the tories of Edogawa Rampo, a wonderfully weird Japanese mystery/horror writer.
