Yoshimi Iwasaki is a Japanese singer and actress who was born on June 15, 1961, in Tokyo, Japan. While she is primarily recognized for her successful career as a pop singer, her professional activities include work as a voice actress in anime. She is the younger sister of renowned singer Hiromi Iwasaki.

In the context of anime voice acting, Iwasaki is known for providing the voice of the character Otomi Murai in the 1981 anime television special Sugata Sanshiro. This production was part of the Nissei Family Special's "animated literature series" and was based on the novel by Tsuneo Tomita. Her involvement in anime also includes a voice role in the 2021 feature film Belle, where she voiced a character named Nakai. Furthermore, her voice work extends to dubbing foreign productions into Japanese and narrating for the animated series Ojarumaru.

Beyond these specific credits, Iwasaki's most significant and enduring connection to anime is through her music. She is highly notable for having performed the majority of the theme songs for the immensely popular anime television series Touch. This contribution remains a hallmark of her career. In 2008, she joined the fantasy band Sound Horizon as a vocalist for their story CD Moira, though she left the group before their subsequent concert. Her career also includes numerous live-action television and film acting roles since the late 1970s.
