Aug 27 (NHK) - Police in Japan are on alert for conflicts between two rival gang groups as Sunday marks two years since they split up.
Members of Japan's largest crime syndicate, the Yamaguchi-gumi, broke away from the group and set up the Kobe Yamaguchi-gumi in 2015.
The National Police Agency says the Yamaguchi-gumi had 11,800 members and the Kobe Yamaguchi-gumi had 5,500 members as of the end of 2016.
The agency suspects the two groups have been involved in 97 conflicts since they broke up. It says 385 gang members were involved.
