On 12 October 1960, Inejirō Asanuma (浅沼 稲次郎, Asanuma Inejirō), chairman of the Japan Socialist Party, was assassinated at Hibiya Public Hall in Tokyo. During a televised debate, 17-year-old right-wing ultranationalist Otoya Yamaguchi charged onto the stage and fatally stabbed Asanuma with a wakizashi, a type of traditional short sword.

The assassination weakened the Japan Socialist Party, inspired a series of copycat crimes, and made Yamaguchi an enduring hero and subsequently a martyr to various Japanese far-right groups, including the Greater Japan Patriotic Party of which Yamaguchi had been a member.
