Yoshizawa was a fourth generation member of Morning Musume, along with Ishikawa Rika, Tsuji Nozomi, and Kago Ai. She was selected from the third round of Morning Musume auditions on ASAYAN in early 2000. She debuted on the group's ninth single "Happy Summer Wedding."
In July 2000, she replaced Ichii Sayaka in Petitmoni and went on to release three singles and one album with the subgroup. When the subgroup's line-up was reshuffled in 2002, with Ogawa Makoto and Ayaka replacing Goto Maki and Yasuda Kei, Yoshizawa became the new leader. However, unlike the other reshuffled subgroups Tanpopo and Minimoni, the new line-up of Petitmoni never released a single. They had one original song, "WOW WOW WOW," but it was only released on the Petit Best 4 album and performed during concerts.
She was made the center on Morning Musume's 13th single "Mr. Moonlight ~Ai no Big Band~," which firmly established her tomboy character and gave a huge boost to her popularity.
Yoshizawa was placed in Morning Musume Sakura Gumi in January 2003 and released two singles as a part of the subgroup before it went inactive.
With Iida Kaori's graduation in January 2005, Yaguchi Mari became the leader of Morning Musume and Yoshizawa became the subleader. However, when Yaguchi abruptly resigned from the group in April 2005, Yoshizawa was bumped up to the leader position with Fujimoto Miki as subleader.
In April 2006, she was named an official supporter of the Japanese women's soccer league, Nadeshiko League.
She graduated from Morning Musume on May 6, 2007, at the Saitama Super Arena performance at the end of the Morning Musume Concert Tour 2007 Spring ~Sexy 8 Beat~. From there, she joined the Hello! Project Elder Club and also became the leader of Ongaku Gatas.
Yoshizawa, along with the rest of the Elder Club, officially graduated from Hello! Project on March 31, 2009 (i.e. the end of the agency's fiscal year). However, the Elder Club graduation concert was held on February 1, 2009, at Yokohama Arena. She became a mother in 2016 of a boy.
