The recent fracturing of the Yamaguchi-gumi, the country's largest and most powerful crime syndicate, will considerably weaken the gang organization and all yakuza groups in general, two noted experts told a news conference Tuesday in Tokyo.

"I believe all crime syndicates will lose momentum further and further. This is not limited to the Yamaguchi-gumi," Atsushi Mizoguchi, a noted journalist who has written extensively about yakuza-related crimes, told a meeting at the Foreign Correspondents' Club of Japan.

Mizoguchi pointed out that police statistics have shown that the number of yakuza groups have decreased rapidly in recent years after various legal regulations against crime syndicates have been strengthened.
