Raised in Tokyo, bilingual with her multicultural family, Kiko had an interest in music from a young age. At 15, she won a national international school talent contest for her performance of "Summer Time" and she started hosting a national radio show the following year. She was soon after selected to be the lead cast for a kids musical TV show on NHK called, "Eigo De Asobo." She gained popularity among families and began to also perform live shows and events. 

In 2016, she released her first album, a pop album for children, called Kodomo Lounge Eigo and toured Japan. She since has released a second album as well as a Christmas album.

In 2020, Kiko was awarded Best Actresses award for her role in "Aida" (In Between) from Best Shorts Film Competition (LA, USA). She has since received 6 best actress awards, and continues to perform through singing and acting, with plans on releasing more music for a grownup audience in 2022.
