Hey! Say! JUMP

A ninemember Japanese boy band under the talent agency Johnny Associates. The group is split into two subgroups: Hey Say 7 which composed of the younger members and Hey Say BEST the older members. Hey Say JUMP originally debuted with ten members the largest group in Johnnys history. But in 2011 Ryutaro Morimoto was indefinitely suspended from the group following an underage smoking scandal. Hey Say JUMP is considered an expansion of the temporary group Hey Say 7. The name Hey Say refers to the fact that all the members were born in the Heisei period and JUMP is an acronym for Johnnys Ultra Music Power. Source: Wikipedia
