The man from shimizu (1982)

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.
