Birth place: Tokyo, Japan

In her high school days, Kojima Mayumi learned about Rosemary Clooney and quickly got hooked on that kind of 50's American music. The only turn off was the English language, so she decided to write her own songs in Japanese. At the age of 18 Mayumi completed her first demo record Manatsu no Umi, and so began her music career. Her official debut was in 1995 with the single Kekkon Soudanjo.
