National Geographic Inside Tokyo Mafia (2013)
Tokyo. Orderly…modern…and seemingly safe. But this vast neon city hides a dark secret. For the millions who live here, it's something you don't see every day, and you may never encounter it face to face. For people on the inside, however, nothing could be more obvious than the power of Japan's infamous organized crime syndicates known as the yakuza. This evocative and groundbreaking documentary takes you inside this secretive underworld to meet the real yakuza, thugs and high-ranking bosses, plus the people who write about their every move, and the cops who track them down. Incredible personal stories and candid interviews reveal an organization both honorable and corrupt, violent and restrained, compassionate and driven by an insatiable greed.
