Kodo-kai is a Japanese organized crime group, often considered a faction of the larger Yakuza syndicate. Established in the 1980s, it is primarily based in Nagoya and is known for its involvement in various illegal activities, including extortion, gambling, and drug trafficking. The group has a reputation for its strict code of conduct and loyalty among its members. The Kodo-kai is recognized for its hierarchical structure, where senior members hold significant influence over younger recruits. The organization has faced increased scrutiny and law enforcement pressure in recent years, leading to efforts to curb its activities and diminish its power within the Yakuza landscape.
