Hey! Say! JUMP

Hey! Say! JUMP is a Japanese band with ten members.
Ryosuke Yamada, Yuuri Chinen, Keito Okamoto, Yuto Nakajima, Kota Yabu, Hikaru Yaotome, Kei Inoo, Daiki Arioka, Yuya Takaki, and Ryutaro Morimoto. Hey! Say! JUMP has some of the best concerts I've ever seen. Although I can't find them anywhere it seems. If anyone knows where I can see one of their concerts please tell me in the comments.

Buono!

This group is also Japanese. Buono! has three members. Airi (愛里) Suzuki (鈴木), Miyabi Natsuyaki (雅夏焼), Momoko (桃子) Tsugunaga (I can't get her last name to type correctly) but I've got it in English. My favorite songs that they have are Bravo Bravo, and Renai Rider.
