According to the sources, the Tokyo-based Matsuba-kai split due to internal strife. Beginning several years ago, the gang had experienced problems related to promotions of upper-level members.
As a result, certain members are expected to form a new syndicate. Police will proceed with measures to recognize the new gang under the Anti-Organized Crime Law.
As of the end of last year, the Matsuba-kai, whose headquarters is in Taito Ward, had about 650 members. In addition to Tokyo, the gang maintains significant operations in Tochigi and Ibaraki prefectures.
