Hotsprings Holiday (1968)

Original title: Onsen gerira dai shogeki

Two rival groups of gangsters vie for control of a tiny port town in northern Japan. Daisuke, a member of the older of the two gangs, and Kosuke, a hoodlum in the newer gang, both fall in love with the daughter of an inn proprietor, even though she evinces more interest in improving the town than in their romantic advances. Eventually, the two hoodlums come to respect her efforts and decide to join forces in ridding the town of all gangsters. The two men succeed in restoring peace to the town and, rejected by the innkeeper's daughter, they leave town as friends.
