At the age of five, Sawada became a member of the Otowa Basket Lily Association and started singing nursery rhymes and appeared as a child actor.
She appeared in a TV commercial for "Panshiron" sponsored by Rohto Pharmaceutical Co. in 1968, alongside Kiyoshi Atsumi.
At that time, young female singer-songwriters were rare in Japan, but she benefited from her Japanese idol good looks and attracted a male audience.
In October 1989, she hosted the KBS Kyoto radio program "Hyper Night" every Thursday.
She has also hosted "Paradise afternoon – Subete ni Arigato" every Monday at the Japanese FM's community radio Music Bird.
