Mamoru Watanabe

After her husband's suicide, young and beautiful Mitsuko Fuji feels alone and helpless -- until one of her husband's major creditors, Mr. Kito, offers a sympathetic ear and a cancellation of all debts. However, Mitsuko soon learns that Kito's intentions are anything but pure, as she's forced to become his personal concubine. Her only, improbable hope for redemption lies with her one true admirer: Kito's very own son.

Tachibana is a drunk whose gambling compulsion ends up putting him in a bad way with the local Yakuza. Unable to pay his debt, he hocks the deed to his wife Izumi's restaurant (which she inherited from her now deceased father) in order to stay out of trouble with the thugs.

Pinku from 1972.
