The Kyosei-kai is known for its history of fierce conflicts with various other yakuza groups, and therefore, the Kyosei-kai is thought to be most responsible for creating Hiroshima's "town of violence" image.[2] Notably the Kyosei-kai has been in conflict with the Yamaguchi-gumi, the largest yakuza syndicate, since the early 1960s.
The Kyosei-kai was a leading member of two anti-Yamaguchi federations, the Kansai Hatsuka-kai (formed in 1970) and the Nishinippon Hatsuka-kai (formed in 1989), and has formed a new anti-Yamaguchi federation named the Gosha-kai since 1996 with three other Chugoku-based organizations, the Kyodo-kai, the Asano-gumi, the Goda-ikka, and the Shikoku-based Shinwa-kai.
