Yamaguchi-gumi Split and Yakuza Gang War
Japan's 1992 Anti-Boryokudan Act and subsequent local ordinances had steadily squeezed the Yamaguchi-gumi's finances and membership over two decades without dissolving the syndicate, which continued to operate as a semi-visible confederation of affiliated gangs. On 27 August 2015, a dispute over leadership succession and revenue-sharing under sixth-generation boss Kenichi Shinoda caused several of the syndicate's most powerful constituent gangs, including the Kobe-based Yamaken-gumi, to break away and form a rival organization, the Kobe Yamaguchi-gumi - the group's first major split in over thirty years. A further 2017 schism produced a third faction, the Ninkyo Yamaguchi-gumi. The rupture set off a prolonged, low-intensity but sporadically lethal conflict between the rival factions, with Japan's National Police Agency recording more than 200 clashes and at least seven suspected murders between 2015 and 2019, prompting authorities to place the syndicates under special anti-organized-crime surveillance designations that further restricted their members' ability to rent property, open bank accounts or operate businesses. The main Kobe-based rivals, the original Yamaguchi-gumi and the Kobe Yamaguchi-gumi, declared a formal truce in April 2025, by which point sustained legal pressure and the feud itself had substantially reduced yakuza membership nationwide.
