3. Street Mobster (1972)
Director: Kinji Fukasaku
Kinji Fukasaku's Street Mobster centers on a low-ranking thug named Isamu Okita (played by Sugawara), who's not at all happy about America's presence in Japan. Noboru Ando’s character, meanwhile, is an older, much wiser gent who accepts Japan’s changing social climate. But his presence doesn't stop Okita from making his mark in the yakuza world.
Street Mobster not only marked the beginning of a new direction for the genre, but it also started the working relationship between Fukasaku and Sugawara, which led to the classic Battles Without Honor And Humanity (a.k.a. Yakuza Papers) series.
