On Monday, Johnny’s Jimusho held a press conference to announce the formation and debut of a new unit, named Hey! Say! JUMP (short for Johnny’s Ultra Music Power). The group is the largest Johnny’s act in history, featuring 10 members in all.
JUMP is an expansion of the Hey! Say! 7 unit that formed earlier this year. Five members have been added, and the lineup has been split into two sub-units. Hey! Say! Best will consist of the five high schoolers: Kota Yabu, Yuya Takaki, Kei Inoo, Hikaru Yaotome, and Daiki Arioka. The younger members will become the new Hey! Say! 7, consisting of Yuto Nakajima, Keito Okamoto, Ryosuke Yamada, Yuri Chinen, and Ryutaro Morimoto. Together, the members of JUMP have an average age of 15 years old.
