Japan's organized crime syndicates appear to be embroiled in something of a power struggle.
Yoshinori Oda, who heads a splinter group that left the Yamaguchi-gumi called the Ninkyo Yamaguchi-gumi, was attacked as he left his house in Kobe on Sept. 12. Oda's bodyguard, Yuhiro Kusumoto, was killed in the attack.
Police later issued a warrant for Tatsumi Hishikawa's arrest over the attack. Hishikawa is a member of the Kobe Yamaguchi-gumi, a rival splinter group that broke from the country's largest criminal syndicate in 2015.
