After covering Celine Dion's "Because You Loved Me" in 2007, Fukuhara made her major label debut through Sony Music Japan in 2008.

Fukuhara's debut album Rainbow (2008) was a commercial success, becoming certified gold by the RIAJ and spawning the top 30 singles "Change", "Himawari", "Yasashii Aka" and "Love (Winter Song)".

The leading track of The Soul Extreme EP, "O2" featuring singer Ai was a success, allowing Fukuhara to release a second extended play in the series, The Soul Extreme EP II, led by the song "Get Up!"

In 2015, Fukuhara set up an independent music label, Happy Field Records, and in December of the same year released an extended play of new material, Something New.
