Born in Tokyo on 28 June 1985, Nakamura began studying music at a young age. She taught herself to play the piano, guitar, and the drums at age ten, and began to write her own songs at the age of fifteen. She entered herself in various music competitions at that time and garnered attention when she won the Katsushika Band Festival, making her the first (and thus far only) solo artist to do so. In 1999, at the age of fourteen, she released an indie label album called Shouchikubai as her prize.
2006-early 2007: Switch to Avex Trax and Ten Made Todoke
In 2006, she switched to a major label, the popular Avex Trax. Her first major label single "Yogoreta Shitagi" was released on her birthday, and received minor attention. "Yogoreta Shitagi" was written about an ex-boyfriend who was cheating on her and is written from the former boyfriend's point of view. Nakamura called this individual on the telephone to explain that the song she had written about him was to be her debut single.
Her second single "Tomodachi no Uta" received greater attention, and placed in the Top 150 at #150 on the Oricon charts. However, it was not until Nakamura revealed on the talk-radio program All Night Nippon that she was born male and had undergone sex reassignment surgery that she received major attention. Her explanation garnered a lot of media attention, and her single rose to #9 on the Oricon. "Tomodachi no Uta" became the theme song for the popular television drama Watashi ga Watashi de Aru Tame ni, a primetime television drama about a young transsexual woman; Nakamura even received a small cameo on the program.
Nakamura wrote "Tomodachi no Uta" when she was fourteen-years-old; notably, it was the first song she ever wrote. She wrote the song to say goodbye to the friends in junior high she would never see again.
Her third single, "Watashi no Naka no Ii Onna," entered the Oricon at #39. On the same day "Watashi no Naka no Ii Onna" was released, the song "Chewing Gum," written by Nakamura for the band AAA, debuted on the Oricon. Her two songs competed with one another for four weeks.
Her first album Ten Made Todoke was released on 1 January 2007. A month later she released "Kaze ni Naru," her fourth single. "Kaze ni Naru" was the theme song for the film Sakebi.
Her song "Kakeashi no Ikizama" was used as the closing theme for the anime series Reideen.
Nakamura intended to be a singer and songwriter from a very young age; she explained on a talkshow that she had never dreamed of being anything other than a singer.
She has a calico cat named Paa.
She played the flute in her high school band.
In a television interview with Ando Yuko, she explained that she had originally hoped to maintain her career without explaining that she had undergone sex reassignment surgery, but changed her mind so as to be honest.
