Jinsei gekijô (1983)
This one starts with a group shot of four Asian women in their 20s, all with black hair, wearing traditional Japanese clothing. They’re chatting in a dimly lit room. Then it cuts to two of them getting cozy in a bath, one with a muscular build and tattoos. The next scene shows them getting intimate on the floor. One of the women has a surprisingly petite frame. A later scene shows one woman with blood on her hand and another holding a knife. The traditional Japanese setting and clothing add an interesting twist to the intimate scenes.
