Jinchu Hattori is the father of Kanzo and Shinzo Hattori. He exists solely within flashback sequences throughout the narrative, never appearing in the series' present timeline.

His documented activities include facing off against the character Perman in at least one crossover episode with the series "Perman," confirming his place within that broader shared fictional universe.

A season 5 flashback reveals Jinchu Hattori was killed; the specific circumstances of his death remain undisclosed. His origins, personal history, and relationship with his wife also remain unexplored within the available material.
