Weekly Young Magazine (Japanese: 週刊ヤングマガジン, Hepburn: Shūkan Yangu Magajin) is a Japanese weekly anthology magazine published in Tokyo each Monday by Kodansha. The magazine started on June 16, 1980, and is targeted at the adult male (seinen) demographic. It was published bimonthly (under the title Young Magazine (ヤングマガジン, Yangu Magajin)), on the second and fourth Mondays of every month, until switching to a weekly publication in 1989. 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. The magazine usually features color photos of pinup girl gravure idols (グラビアアイドル, gurabia aidoru) on the cover and first few pages of each issue. Since December 9, 2009, Kodansha has published a monthly sister magazine, Monthly Young Magazine (月刊ヤングマガジン, Gekkan Yangu Magajin), a retitled makeover of their previous publication Bessatsu Young Magazine (別冊ヤングマガジン, Bessatsu Yangu Magajin), which had published a total of 36 bimonthly issues during its existence.
