The yakuza is a term used to describe organized crime syndicates in Japan. These groups are known for their strict codes of conduct, hierarchical structures, and involvement in various illegal activities, including gambling, drug trafficking, and extortion. The yakuza often have a significant presence in Japanese society and are sometimes involved in legitimate businesses as well. Members of the yakuza are easily recognizable by their elaborate tattoos and distinct hairstyles. The organization has a complex history, with roots tracing back to the Edo period. Despite their criminal activities, some yakuza groups engage in charitable work and disaster relief, which complicates their public image.
