The Dōjin-kai (道仁会) is a yakuza gang based in Kurume city, Fukuoka, Japan. It is the largest yakuza group in Kyūshū, with approximately 750 members.
Members of Kitamura-gumi, affiliated with this syndicate, killed four people in 2004, for which four people were later sentenced to death.
Its leader was Seijiro Matsuo (松尾 誠次郎). When he announced his resignation on 10 May 2006, a war broke out between the headquarters and a splinter group in Ohmuta who, naming themselves the Kyushu-Seidō-Kai (九州誠道会) aligned themselves with Yamaguchi-gumi, Dōjin-kai's rival and the largest gang in Japan. Seven people were killed during the course of the war. In one incident, a gangster under the influence of amphetamines walked into a hospital and shot twice into an innocent man mistaken for a rival. In another, the gang's headquarters was sprayed with machine-gun fire.
On June 13, 2007, Zenji Tsurumaru was killed. On June 19, Hidenori Irie was killed. On August 18, the leader of Dōjin-kai, Yoshihisa Onaka was killed. On November 8, a civilian Hiroshi Miyamoto was killed by mistake while receiving treatment at a hospital. On November 12, Shigeki Koga was killed. On November 27, Yoshikazu Matsuo, one of chairmen, and his driver were killed. Both groups announced a cease-fire on December 18 and on February 5, 2008, the war officially ended.
Locals fed up of the yakuza violence hired a lawyer, Osamu Kabashima, to file a legal case against the Dojin-kai in a bid to drive them out of the town.
