Lords of the Mafia: Japan takes a comprehensive look at an area some don't consider when thinking about the stereotypically Italian- and New York-based Mafia -- Japan. This edition of the popular Lords of the Mafia series delves into the legendary yakuza. Not just a subject of kung fu films, the yakuza have one of the most compelling, if deadly, histories of all of the world's mobs. This production was originally aired on PBS and Court TV.
