Black Cat's Revenge (1970)

Meiko Kaji spends 3 years in jail for avenging her Yakuza father, and on her release she inherits the leadership of the Tachibana gang. They're quite a nice bunch, for Yakuza, but a nasty rival gang are bent on taking over their territory. As if that wasn't bad enough, she appears to be under the curse of a black cat that got a taste of her victim's blood...

The film takes a broadly familiar period-Yakuza story and mixes it up with elements of horror and... strangeness, making for an intriguing cocktail of styles, moods and ideas. Teruo Ishii was one of the premier visual stylists of the Japanese exploitation wave, and this film shares the style even though it's relatively light on the exploitation. The plot is straightforward but the details make it interesting, and having Meiko Kaji as the lead actress certainly helps there too.

Good stuff!
