Hey Say Jump is an 8-member [[JapanesePopMusic Japanese]] {{Boy Band}} that debuted under the agency, Johnny's and Associates. Their name comes from being the first Johnny's group where all members were born in Heisei era, and JUMP is an initialization of "Johnny's Ultra Music Power".

The creation of Hey! Say! JUMP followed on the heels of the temporary junior unit Hey! Say! 7(not to be confused with the Hey! Say! subgroup of the same name), which sang the theme songs for the Lovely Complex anime.

They are divided into two sub-units; Hey! Say! BEST, which comprises the older members and Hey! Say! 7 which comprises the younger ones respectively.

----
!!Tropes in their work:
* {{Ascended Extra}}: All of them were backup dancers for some of their sempais and were also members of various Johnny's Junior units before their official debut.
** Special mention goes to Yamada here as he was never one of the guys that was always in front when he started out, but slowly
* {{Boy Band}}: Hello, they are Johnnys.
* {{Darker and Edgier}}: As of their 2008 single, ''Your Seed,'' they started adopting a more mature image. Zigzagged as they have not completely let go of their cute image.
* {{Gratuitous English}}: Well, they are Japanese.
* {{Hotter and Sexier}}: While their image is overall the colourful kawaii type, they repetoire has increasingly had more of this mixed in. Banger Night deserves special mention.
* {{Ship Tease}}: Now where do we start? Most popular couples include Daiki/Yamada, Yamada/Chinen, Yuto/Yamada, Yabu/Hikaru and Takaki/Yamada.
* [[TeenIdol Teen Idols]]: They were the youngest Johnny's group until Sexy Zone's debut.
