Rie Miyazawa is a highly acclaimed Japanese actress whose career spans live-action film, television, and stage, with a smaller but notable body of work in voice acting for animated projects. Born in Tokyo on April 6, 1973, she began her career as a child model and made her acting debut at the age of fifteen in the 1988 film Seven Days War, a performance that earned her the Japan Academy Award for Newcomer of the Year. While she rose to prominence as a leading actress and former teen idol, winning numerous accolades including multiple Japan Academy Film Prizes, her voice acting roles have contributed to her diverse filmography.

Miyazawa's voice acting credits include a range of films and series. She provided the voice for Iratsume of Fujiwara in the 2005 animated film The Book of the Dead. She narrated the 2009 nature documentary Oceans. In 2019, she returned to the role of Hitomi Nakayama, this time as a voice actor, for the animated film Seven Days War, a new adaptation of the work that marked her debut. More recently, she voiced the character Romi in the 2023 anime series Phoenix: Eden17 and its companion film Phoenix: Reminiscence of Flower, based on the classic manga by Osamu Tezuka. Her other voice work includes the Japanese-dubbed version of the animated film The Hunchback of Notre Dame II, where she voiced Madellaine, and a role in the 2014 puppetry series Sherlock Holmes.

Throughout her extensive career, Miyazawa has been recognized as one of Japan's foremost actresses, with a reputation built on powerful and nuanced live-action performances in films such as The Twilight Samurai, for which she is perhaps best known internationally. Her voice acting, while a smaller facet of her body of work, demonstrates her versatility and ongoing involvement in a variety of storytelling mediums, from major film productions to prestigious animated adaptations.
