Sandii's debut album, "Sandi Ai", is a mix of Japanese originals and covers of well-known songs by John Lennon and Olivia Newton-John.
Sandii met Makoto Kubota in 1976, when he was a guest on her NHK TV show and afterward joined his band Yuyake Gakudan ("Sunset Gang") as a backup singer.
On the soundtrack of Lupin The Third Sandii performed the songs "I Miss You Babe" and "Love Squall"; the latter was a single release paired with the theme of the TV series by Yuji Ohno.
In 1978, Sandii sang the end title theme for the Japanese release of Agatha Christie's Death on the Nile, which became a top 20 hit in Japan.
With limited time and budget, the album "Mystery Nile" consists of disco and pop cover versions including "Dancing Queen" by ABBA.
In late 2005 Sandii achieved the rank of Kumu Hula and celebrated with an event at a shrine in Ise, with old friend Haruomi Hosono providing the music.
