Police in the city of Okayama were on alert after the deadly shooting of a senior member of a branch of the Kobe Yamaguchi-gumi crime syndicate. The police believe the case is linked to an ongoing power struggle between the Yamaguchi-gumi crime syndicate, the nation’s largest yakuza group, and the Kobe Yamaguchi-gumi splinter group, which broke away last August. Since the split, firearms have been used in eight of 75 incidents recognized as gang clashes.
