Hayami became interested in voice acting while attending elementary school. In 2004, she attended junior class of Nihon Narration Engi Kenkyūjo, a voice acting training school. She was curious how Audrey Hepburn's voice was dubbed after learning that what she heard wasn't the actress' original voice. She recalls how she left a flyer for the voice acting school on the kitchen table, only to be told by her mother to pick up the phone & call herself.
