Weekly Young Magazine (Japanese: 週刊ヤングマガジン Hepburn: Shūkan Yangu Magajin) is a Japanese weekly seinen manga anthology magazine published in Tokyo each Monday by Kodansha. The magazine was started on June 23, 1980 and is targeted at the adult male (seinen) demographic. The numerous serial stories running concurrently in Young tend to be violent, sexy, action-oriented, and imaginative, with an earthy sense of humor. The magazine's core readership has been dismissively characterized in the past as bikers and delinquents. The chapters of the series that run in Weekly Young Magazine are collected and published in tankōbon volumes under the "YoungKC" imprint every four months.
