Hidaka was born in the Kudan area of Chiyoda, Tokyo, Japan,[1] where she attended Fujimi Elementary School.

She began her career as an idol star, but switched to voice acting, and was employed by the talent management firm 81 Produce until 2006.

She switched to the current usage (日高) around 1995 when she found that it was written that way already on many things and after friends recommended the kanji with the lower stroke count.

She has also done voice-over commercials for programs and games, in which she plays a role for 3rd Super Robot Wars Alpha: To the End of the Galaxy.
