The Man from Shimizu.

On the day his mother dies, young gambler Jirocho swears in front of her grave that he'll never gamble again. But, that night, Jirocho heads to a gambling den, where he bets the condolence money for his mother's funeral. No surprise to learn he loses the lot. Not the hard-boiled yakuza story it seems, this is a comedy featuring many new artists who were making a name for themselves at the time.
