Police ordered Japan's largest underworld organization, Yamaguchi-gumi, and Tokyo's Kokusui-kai syndicate to suspend the use of five of their offices in the wake of a series of shootings reported this week in Tokyo and neighboring areas, they said.
Police believe the shootings stemmed from the fatal shooting early Tuesday in Tokyo's Shibuya Ward of a gangster affiliated with Kokusui-kai, they said.
No injuries have been reported in the 16 shootings in Tokyo and the nearby prefectures of Kanagawa, Saitama, Chiba, Ibaraki and Tochigi since Wednesday, police said.
