Yakuza are members of transnational organized crime syndicates originating in Japan. What does one imagine when hearing the word "yakuza"? Father-son relationships between the head of the gang (who has an authority above exception) and other members, self-devotion, honor, samurai code, "sharp suits", strong traditions. There is another side of the coin: drug-dealing, racketeerings, backings, gambling business, sex trafficking, real estate scams. The special arrangement between clansmen – in the situation when someone not-so-pleasant militates against the yakuza clan, then other members must strike back. No exclusions. Everything is delicate and strict.
