Yakuza (ヤクザ), also known as gokudō (極道), are members of transnational organized crime syndicates originating in Japan. The Japanese police, and media by request of the police, call them bōryokudan (暴力団), while the yakuza call themselves ninkyō dantai (任侠団体 or 仁侠団体). The yakuza are notorious for their strict codes of conduct and organized nature.
