Hey! Say! 7 is a Japanese J-pop idol group formed on April 3, 2007 under Johnny & Associates. The group consists of Daiki Arioka, Yuri Chinen, Yuto Nakajima, Yuya Takaki, and Ryosuke Yamada.
The name Hey! Say! refers to the Heisei era, reflecting the period in which the members were born. The group is also closely tied to the wider Hey! Say! JUMP project in Johnny’s catalog, which makes Hey! Say! 7 an important reference point for listeners searching for the group’s members, early releases, and place in the history of Japanese idol music.
