Rising to fame with the hit "The Parting Song", released in 1977, she has since seen a successful career as a singer-songwriter, primarily in the early 1980s. Four of her singles have sold more than one million copies in the last two decades, including "Earthly Stars", a theme song for the Japanese television documentary series Project X. Nakajima performed in experimental theater every year-end from 1989 through 1998. The idiosyncratic acts featured scripts and songs she wrote, and have continued irregularly in recent years. In addition to her work as a solo artist, Nakajima has written over 90 compositions for numerous other singers, and has produced several chart-toppers. Many cover versions of her songs have been performed by Asian singers. She is the only musician to have participated in the National Language Council of Japan.
