Yakuza

Yakuza (ヤクザ or やくざ ?), also known as gokudō (極道?), are members of traditional organized crime syndicates in Japan. The Japanese police, and media by request of the police, call them bōryokudan (暴力団?, "violence group"), while the yakuza call themselves "ninkyō dantai" (任侠団体 or 仁侠団体?, "chivalrous organizations"). The yakuza are notorious for their strict codes of conduct and very organized nature. They are very prevalent in the Japanese media and operate internationally with an estimated 80,900 members in 2009, the last year for which an estimate is available.
