The Asano-gumi was formed in 1945 as a bakuto organization named the Oyama-ikka (大山一家, Ōyama-ikka) by Kunio Oyama. The group restarted as the Asano-gumi with the head of Shin'ichi Asano in April 1952 following Oyama's retirement. Yoshiaki Kushida succeeded as president in September 1983.[3]
Condition
The Asano-gumi has been based in Kasaoka, Okayama ever since its formation.[3]
The Asano-gumi caused conflicts with the Yamaguchi-gumi and the Kyodo-kai in the late 20th century. In one notable case, Asano member(s) shot and murdered two Yamaguchi members in Kurashiki in 1987, as a retaliation for an earlier attack by Yamaguchi member(s) involving carving knives against two Asano members.[3]
