The conflict began when a succession dispute inside Dojin-kai caused senior members to break away and establish Kyushu Seido-kai. Gun attacks and explosive attacks followed. In 2007, a civilian hospitalized in Saga was mistakenly identified as a rival and shot dead, demonstrating how far the conflict had spilled beyond gang members. Authorities later used special conflict-designation powers to suppress the violence.
