Houmoto was born in Tottori Prefecture and she grew up in Chiba, Guangdong, and Osaka. She is a Hafu with a Japanese father and a Chinese mother. Her father wanted her to learn Chinese, so they lived in Guandong from 2004 to 2012. At that time, she used her Chinese name Yang Ming (楊明). Most of the time, Houmoto talks to members of her family with a combination of Chinese and Japanese.
After she graduated from high school, Houmoto gave up going to the university and went to Tokyo alone with 100000 JPY to pursue her dream being a voice actress.
