Project as a fifth generation member and the former leader of the Japanese pop group Morning Musume and was a member of the group Tanpopo and the leader of Athena & Robikerottsu, as well as participating in the shuffle units Happy 7, 7AIR, ZYX-α and H.P. All Stars. She was also a member of the Morning Musume splinter group, Morning Musume Sakura Gumi.

She joined Morning Musume in 2001 along with Takahashi Ai, Konno Asami and Ogawa Makoto. Niigaki was the sub-leader of Morning Musume, inheriting the title from the the former leader Takahashi Ai and was sub-leader until Takahashi's graduation. As of 2009, she was the longest serving sub-leader.

Niigaki was also the leader of Hello! Project. On January 2nd, it was announced that Niigaki Risa will graduate from their next Spring Tour 2012 "Ultra Smart". On May 18 2012, she graduated from Morning Musume and Hello! Project alongside Mitsui Aika at Nippon Budokan.

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 June, she also debuted in a shuffle unit, as part of Happy 7, coincidentally with two other members of her generation (Takahashi and Ogawa).

Later in September, all of the fifth generation members were placed into subgroups. Niigaki was placed into Tanpopo as a member of the third generation, along with Konno Asami. The new grouping only managed to release one single before becoming inactive.

Niigaki continued her career in Morning Musume during 2002 and into 2003. She also participated in the 2002 Happiness Groups as a member of Happy 7. Niigaki also released a joint photobook with the rest of the fifth generation members.

2003
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. Niigaki was placed into Sakura Gumi and released two singles with the group before the two groups merged together and formed Morning Musume once more. Niigaki was included in the 2003 Elemental Shuffle Groups as a member of 7AIR.
