The Japanese Yakuza is a term used to describe organized crime syndicates in Japan. These groups are known for their strict codes of conduct, hierarchical structure, and involvement in various illegal activities, including gambling, drug trafficking, and extortion. The Yakuza often have tattoos that symbolize their affiliation and personal stories, which are an important aspect of their identity. Historically, the Yakuza emerged in the 17th century, initially as street merchants and gamblers. Over time, they evolved into more structured organizations, with a significant presence in Japanese society. Despite their criminal activities, some Yakuza groups engage in community work and disaster relief, complicating their public image.
