ジャニー喜多川
The name was supposed to be Johnny's WEST4, and the original members were Daiki Shigeoka, Akito Kiriyama, Junta Nakama and Nozomu Kotaki, however they later found that having the number "4" in their name was inappropriate due to the Japanese superstition that the number is unlucky. The 4 members used this chance to ask Johnny Kitagawa, the president of the agency, to add 3 more members to the group, namely, Ryusei Fujii, Tomohiro Kamiyama and Takahiro Hamada, and the name was changed to Johnny's WEST.
