Originally a novel by Yamazaki Toyoko, and later a 1974 movie, Karei naru Ichizoku depicts the conflicts within the Manpyo family, famous in Kansai's financial circles, amidst the tumultuous reorganization of the financial industry of the late 1960s. Unlike the book, the eldest son, Teppei, and not the father, Daisuke, is the central character of the drama. This drama is set in the late 1960s decade of Japan and depicts the rivalry between Manpyo Daisuke (Kitaoji Kinya), a powerful banker, and his eldest son, Manpyo Teppei (Kimura Takuya), the executive managing director of a steel firm. For reasons not yet entirely clear, Daisuke seems to dislike his own son and when Teppei finds out why, the Manpyo family is turned upside down.
