Miyabi Natsuyaki (夏焼 雅, Natsuyaki Miyabi?, born August 25, 1992 in Chiba Prefecture, Japan) is a Japanese pop singer. Her career began in 2002 when she passed the audition for Hello! Project Kids, an all-female adolescent pop group under Hello! Project. Since then, she has continued to sing in that group and has become a part of four smaller groups composed of Hello! Project Kids members—Aa!, Sexy Otonajan, Buono! and Berryz Kobo.
In 2002, Natsuyaki successfully passed the Hello! Project Kids Audition alongside the other members of Berryz Kobo.
Being a member of Berryz Kobo, she also participates in the band's weekly radio show Berryz Kobo Kiritsu! Rei! Chakuseki!.
In that same year, she was cast as a character 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.
In 2003, Natsuyaki was chosen to join the group Aa!, which consisted of another member of Hello! Project Kids, Airi Suzuki and was led by Morning Musume member Reina Tanaka. They released only one single: First kiss released on October 29, 2003. The status of the group as a recording unit is unknown, since they have not released anything since their single in 2003, but the original lineup "reformed" for live performances in 2007. In 2009, Aa! returned from hiatus, and because leader Tanaka Reina had left the group to form the unit High King with other Hello! Project members, Miyabi took over as leader of Aa!
