Since she was young, she decided she wanted to work in either the athletic or entertainment fields.

During her second year of high school, she trained for a year in boxing at the action training school under action director Sakaguchi Tak. She also received full-fledged action training in acrobatics. She attributed this choice to seeing Milla Jovovich in "Resident Evil" and becoming interested in action.

She won the Japan Action Award for Best Action Actress and the Best New Artist award in 2015.
