The Family Game 1983

A sendup of the stereotypical Japanese family: dad is a salaryman jerk, unable to relate to anyone; mom is a hopeless housewife; the older son is a moderate academic success; but the younger son is a rebellious goof-off for whom a tutor must be hired. The tutor, played by the prototypical bad boy actor Matsuda Yusaku, proceeds to blow the entire family apart.
