A number of theories have been put forward on the reasons behind the 2015 split of the country's largest crime syndicate, the Yamaguchi-gumi.
Some say the factions that left the organization and formed a group called the Kobe Yamaguchi-gumi were egged on by the police, who had deliberately encouraged suspicions to grow among rival syndicates. It's worth noting that police officers stood guard outside the new group's headquarters when it announced its existence to the public.
Others believe the split was supported by several former Yamaguchi-gumi syndicate bosses who had been expelled with Tadamasa Goto in 2008. Those involved in organized crime call the cull the "Goto Shock," a nod to the collapse of Lehman Brothers in the same year. Indeed, Goto allegedly bankrolled the Kobe Yamaguchi-gumi, allowing the new organization to get up and running.
