She won awards for composition at an early age, I remember..

But she's been playing piano for a while~
"A piano player since age 4, Otsuka composes and co-produces her songs. She also writes her own lyrics. Her music ranges from upbeat catchy pop/rock music that can be heard in tracks like Happy Days and Sakuranbo to touching ballads like Daisuki da yo and Amaenbo. "
