The Japanese Mafia, known as the Yakuza, is a group of organized crime syndicates in Japan. They are involved in various illegal activities, including drug trafficking, extortion, and gambling. The Yakuza has a complex hierarchy and is known for its strict codes of conduct and rituals, including elaborate tattoos that signify membership and rank. Despite their criminal activities, the Yakuza often engage in community work and disaster relief, which can create a paradoxical image of them as both criminals and benefactors. The group has a significant presence in Japanese society and culture, influencing everything from movies to literature.
