Watch Drifting Clouds (1982)

Drifting Clouds

Retired samurai Kumosuke lives quietly, not to say idly, in Edo (old Tokyo) with his wife and two children, a young boy named Shinnosuke and an infant girl, Ohana. While he nominally runs a courier business to earn a living, he seems to spend most of his time smoking his pipe, drinking sake, and chasing women. The arrival of a Shinsengumi squad led by a young swordswman, Ichimonji Hyougo, disrupts this peaceful routine, forcing Kumosuke to defend himself.
