It's Tough Being a Man (1969)

"Japan's most beloved loser"

Tora-san, an itinerant peddler who is thrown out of his father's house twenty years before but reconnects with his aunt, uncle and sister Sakura. Tora wreaks some havoc in their lives, like getting drunk and silly at a marriage meeting and ruining Sakura's chance to marry someone, as well as just being a real pain to those around him. There is a sentimental side to him also, and the best way to describe him is that he grows on you.
