The Way to Fight (1996)

Original title: 喧嘩の花道 大阪最強伝説

Dangerous street fighter Kazuyoshi Tamai finds out that his rival, Takeshi, is the leader of a gang responsible for a series of assaults. Kazuyoshi is ready to face off against Takeshi, but comic challenges keep his nemesis out of reach. It's not until years later -- when Kazuyoshi becomes a championship boxer and Takeshi is a pro wrestler -- that they meet again in a battle that pits two combatants with very different fighting styles.
