World's Most Dangerous Criminal Gangs

Yamaguchi-Gumi:
Yamaguchi-Gumi is Japan's biggest and most infamous yakuza organization and is named after its founder Harukichi Yamaguchi. It is one of the world’s largest criminal organizations. Its number of active members are estimated at just over 55,000, with thousands more having strong associations. It is certainly the largest of the boryokudan groups, and its membership encompasses approximately 45 percent of the 86,300 yakuza in the Japanese underworld. Its birth can be traced back to a loose labor union for dockworkers in Kobe pre-WWII.  The organization is among the world's wealthiest gangsters, making billions of dollars a year from extortion, guns, drugs, gambling, the sex industry and real estate and construction kickback schemes. Yamaguchi-Gumi is also involved in stock market manipulation and Internet pornography. It is headquartered in Kobe, Japan, but operates all across Japan and has overseas operations in Asia and the U.S. Its current boss, Shinob Tsukasa has declared an expansionist policy and also has multiple groups working overseas.
