ハロー!プロジェクト・キッズ
In 2002, Natsuyaki successfully passed the Hello! Project Kids' Audition alongside other members of Berryz Kobo. As a member of Berryz Kobo, she participated in the band's weekly radio show "Berryz Kobo Kiritsu! Rei! Chakuseki!". That same year, she was cast in "Koinu Dan no Monogatari", however she did not have a large part due to her age. Many members of Hello! Project Kids and Morning Musume participated in this film.
