Nihon No Don (日本の首領, approximately translating as The Japanese Godfather or The Japanese Don) is a Japanese trilogy of organized crime films released from 1977 to 1978. Very loosely based on the real-life exploits of Japan's biggest yakuza gangs, the series was adapted from a novel by journalist Kazuo Kasahara and was produced by Toei, who earlier rewrote the rules of the yakuza genre with Kinji Fukasaku's Battles Without Honor and Humanity.
A yakuza leader must balance his violent tactics necessary for the rough streets of 1960s Tokyo with the domestic needs of his daughters.
An ambitious Kansai yakuza don moves in on Tokyo using financial and political tactics, sparking conflict with a local criminal association.
The three-film saga comes to a conclusion as three leaders of the underworld battle it out to determine who will become Don of Japan.
