2001
In 2001, Niigaki joined Morning Musume as the fifth generation along with Takahashi Ai, Konno Asami, and Ogawa Makoto. Morning Musume producer Tsunku said he chose Niigaki because she "shined during the final studio recording" for the audition song that all the finalists had to sing.

She debuted on the group's 13th single, Mr.Moonlight ~Ai no Big Band~ alongside her fellow generation members.

2002
Her first appearance on a full-length Morning Musume recording was on the album, 4th Ikimasshoi!.

In a surprise move by Tsunku, Morning Musume was split into two halves - Morning Musume Otome Gumi and Morning Musume Sakura Gumi - so that the large group could perform in smaller towns that could not hold the larger numbers the full ensemble needed.
