1.
the second-in-command of an organized group called a {団|だん}, such as a fan club, cheer squad, performing troupe, scout troop, or similar organization
Formed by attaching the prefix 副- (vice-, deputy-) to 団長 (leader of a 団). A 団 is a named, organized group — a troupe, troop, squad, regiment, fan club, cheering section, brass band, circus, martial arts group, or similar body. The 副団長 supports the 団長 in running the group and takes charge in the leader's absence. The word is not usually used for business or political bodies, which take other "deputy" titles instead.
