Takashi Shimura
Kiichi's three oldest children convince his wife to try to have him ruled incompetent in order to keep him from wasting their inheritance on his plan, and they bring him before a three-man arbitration panel that includes Dr. Harada (Takashi Shimura). Harada, a dentist who volunteers with the family court, sympathizes with Kiichi's concerns and points out that the fear of nuclear weapons is present in every citizen of Japan. He wonders aloud whether it may be wrong to rule someone incompetent simply for being more worried than the average citizen, but the panel eventually decides that Kiichi's irrational behavior justifies removing his ability to make the financial decisions for his family by himself.
