This paper aims to deal with repulsive desire for violence in mafia films in Japan and Taiwan. This paper also examines the significance of the films in their contexts when the films were produced. Starting by elaborating on their backgrounds, two films, The Grave of Jingi (1975) and The Women's Revenge (1980) will be analyzed by narratology and Lacanian psychoanalysis.Toei company in Japan initiated the War without Jingi series in post-war Japan. The radical contents of the films congruously correspond to the fervent atmosphere in the Anti-Anpo Protest era.So-called Social Realist Films in Taiwan manifest the same situation. Most of these films were made in the early years in Taiwan's democratic movement. But with many sexy stars' participation and involvement, this genre transforms itself to mimic B films in the west.These films are never great films, but with a Lacanian approach to the object petit à, it is clear that repulsive violence in the mafia films in fact sustains and perpetuates the legitimacy of the subject (characters in films and the audience alike) consciousness living justifiably without moral misdemeanor.
