At the age of 20 she released her first single, Yume Miru Shoujo ja Irarenai on November 8, 1995.
That album won her an invitation to perform on Kōhaku Uta Gassen, a New Year's Eve singing contest between male and female teams of popular singers sponsored by NHK (one of Japan's television networks).
Some music-journalists said that a large part of her fan base, during the 1990s, was the Bōsōzoku (motorcycle gang) youthes especially those in the western areas of Japan.
In 2001, she also released a 'mini-album' (sometime between a full album and a single) with only 7 tracks called the Last Quarter of uncharacteristically soft ballad-style music, recorded during her later months of pregnancy.
This album focused more on ballads and soft music than her well-known rock edge.
Her first music release while working on this album is as part of a limited unit called "Crimson-FANG" for the soundtrack of Kamen Rider Kiva: King of the Castle in the Demon World, having performed on the soundtrack on Kamen Rider Blade in 2004.
and with whom she toured for the album: Aikawa Nanase was married on her twenty-sixth birthday, February 16, 2001 and their first child, a boy, was born on September 6, 2001.
Aikawa is a good friend (as stated in an interview) of Yumi Yoshimura from Puffy.
