上原ひろみ
Tanioka was born in Hiroshima, Japan, where she studied music and composition while in school and enjoyed listening to video game music as her younger brother was a gamer. Among the composers she grew familiar with were Square employees Hitoshi Sakimoto, Nobuo Uematsu and Kenji Ito. Her favorite classical composers at the time were Piotr Paleczny and Hiromi Uehara. Tanioka attended Kobe University, where she studied music and joined a choir. She graduated with a degree in musical performance. Although she had planned on performing music as a career, during college she became more interested in composing than performance, and in video game composition because of her childhood experiences. After graduating, she joined Square (now Square Enix) as a composer in 1998.
