Asano-gumi

Asano-gumi originated from the postwar gambling-group environment around Okayama and Hiroshima. NPA historical material traces the organization to the Oyama-ikka lineage and later formation under Shinichi Asano. Its history includes conflict with larger neighboring groups, making it a useful page for mapping regional competition outside the largest national syndicates.
