Yumi Matsutoya
Her first studio album entitled "Shoujo" was recorded in Los Angeles, produced by Grammy Award winner John Fischbach, with distinguished musicians such as David Campbell, Carole King and Charles Larkey who was King's husband at that time. Owing to her introspective compositions, Itsuwa was often nicknamed "Japanese Carole King", along with other Japanese singer-songwriters like Yumi Matsutoya (who had worked under her birth name "Yumi Arai" during the mid-1970s) and Minako Yoshida.
