Amami was the youngest actress in the company's history to be cast in a top male role.
As an otokoyaku (男役, male role), she belonged to the Moon Troupe (Tsuki).
She was involved in various famous musicals when she was in the company, including Gone With the Wind, where she starred as Rhett Butler, and Me and My Girl.
In May 2013, Amami suffered a mild heart attack after performing in the stage production L’honneur de Napoleon at the Tokyo Metropolitan Theatre.
Although she wanted to return, she decided to bow out of the role on her doctor's advice and wrote a letter of apology to her fans.
