Asuka's musical career began in 2002, when she was chosen with two other girls, Hikaru Koyama and Miho Hiroshige, to form the group LOVE & PEACE.
Later in 2003, Tomoko Kawase, better known as Tommy, had seen potential in Asuka and had produced her first solo single, "♥Wanna be your girlfriend♥", under the Sonic Groove label, a sub-label of avex trax.
The group continued to release singles through 2007, two of which, "NIGHT OF FIRE" and "Sticky Tricky & Bang", featured comedian-wrestler Koriki Choshu.
[citation needed] In the spring of 2007, Asuka released a new solo single, "Asu e no Hikari" (明日への光, Light toward Tomorrow).
However, she contributed a song, Suiren (睡蓮, Water Lily), to the compilation album Flower Festival: Vision Factory Presents, released in March 2008.
