Japanese organized crime, primarily represented by the Yakuza, is a complex network of criminal groups involved in various illegal activities, including drug trafficking, extortion, and human trafficking. The Yakuza has a long history, dating back to the 17th century, and is known for its strict codes of conduct and hierarchical structure. These groups often engage in legitimate businesses as a means of laundering money and maintaining influence. While the Yakuza is the most recognized, other organizations, such as the Boryokudan, also exist. The Japanese government has implemented measures to combat organized crime, including laws targeting the Yakuza's activities.
