Born and raised in Osaka, Hayashi became a performer after her piano teacher sent a tape of her singing to a music producer.

Impressed with Hayashi's talent, a representative of Toshiba Emi's Southeast Asia division arranged to release her debut single, "ake-kaze", on the same day as its Japanese release.

Her debut album, called "Saku" (咲), was released on the same day in Japan, Taiwan, Hong Kong and Mainland China. She has gained fans throughout Japan, Hong Kong, Taiwan, and the United States.

Her hit song, titled "Chiisaki Mono" or "Make a Wish" (English Version), was used in the sixth Pokémon movie, Pokémon the Movie: Jirachi: Wish Maker (Japanese: Nanayo no Negai Boshi; literally "Wishing Star of Seven Nights").^[2] and "Orashion no Tēma ~Tomoni Arukō~" (Oracion's Theme~ Let's Walk Together" was the ending theme to the 20th installation of the Pokémon movie: Pokémon the Movie: I Choose You! Other notable songs include "Hitotsubu no Tane ~Love the Earth~", "Snowdrop", "Jibun Shinjite" and "Mou Ichido Anata ni Aitai".

Hayashi has since recorded in both Japanese and Chinese,^[3] collaborating with Chinese instrumentalist Chen Min on the single, "Tsubane ni Naritai".
