Hagiwara Mai took part in the Hello! Project Kids auditions at the age of 6 and passed, along with fourteen other girls, on June 30. Her audition song was "Te wo Nigitte Arukitai" by Goto Maki.[4]

She made her first appearance in the entertainment industry as a member of 4KIDS, a temporary group that appeared in Minimoni's movie Minimoni the Movie Okashi na Daibouken!.


Hagiwara continued her work within Hello! Project Kids, performing alongside Morning Musume at concerts as backup dancers.

In late 2004 Hagiwara took part in her first Hello! Project shuffle unit, H.P. All Stars, taking part alongside all the members of Hello! Project at the time. The shuffle unit released one single and became inactive by January 2005.


Hagiwara was assigned as a member of Hello! Project group ℃-ute alongside seven other Hello! Project Kids members.[5] These eight members had been passed over when it came to the forming of Berryz Koubou, which had originally been formed to teach the Hello! Project Kids about being in a group by rotating the line-up amongst the kids. Originally ℃-ute was releasing songs on an indie label, but in 2007 they made their major debut.


Hagiwara Mai released four indie singles as a part of ℃-ute in preparation for their major debut in 2007. ℃-ute also released their first album, Cutie Queen VOL.1.


On February 21, ℃-ute released their debut single, "Sakura Chirari." On the first day in the Oricon charts it ranked third, a feat not even accomplished by Hello! Project's mother group Morning Musume (who had ranked 6th on their debut single). With their debut single, they became the youngest group (with the average age of 13) to rank in the top 10. Hagiwara provided minor vocals for their debut single.

However, she spoke to the other ℃-ute members who wanted to continue to work hard together, and Hagiwara stated she would slowly do her best to regain fans' trust and support.
