Mone Kamishiraishi is a Japanese actress, singer, and voice actress born on January 27, 1998, in Kagoshima City, Japan. She is affiliated with the talent agency Toho Entertainment. Her career began in 2011 when she won the评审员特别奖 (Special Jury Prize) at the 7th Toho Cinderella Audition, which led to her signing with the agency alongside her younger sister, actress and singer Moka Kamishiraishi.

Her entry into voice acting came in 2012 with a role in the acclaimed animated film Wolf Children. However, her career as a voice actress achieved international prominence in 2016 when she was cast as the female lead, Mitsuha Miyamizu, in Makoto Shinkai's blockbuster animated film Your Name. Her performance was widely praised and she reprised the role for a cameo appearance in Shinkai's subsequent film, Weathering with You, in 2019. For her work on Your Name, she received the Best Lead Actress Award at the 11th Seiyu Awards.

Beyond these landmark roles, her other significant voice acting credits include providing the Japanese dub voice for the titular character in the live-action CGI film Alita: Battle Angel in 2019 and for Poppy in the Japanese dub of Trolls World Tour in 2020. She also voiced the protagonist Natsume Amano in the 2017 animated film Yo-kai Watch Shadowside: Oni-ō no Fukkatsu.

While her voice acting work is notable, Kamishiraishi maintains a parallel and highly successful career as a live-action actress and singer. She has starred in numerous films and television dramas, such as the live-action adaptations of Chihayafuru and the romantic comedy television series An Incurable Case of Love, for which she won the 104th日剧学院奖 (Drama Academy Award) for Best Actress. Her work as a musical theater actress is also critically acclaimed, with leading roles in productions like the stage adaptation of Spirited Away, where she played the role of Chihiro.

Her career is marked by versatility across acting, singing, and voice performance. A recurring collaboration of note is with director Makoto Shinkai, having voiced the same character in two of his films. In the broader entertainment industry, she has worked with various prominent actors and musicians, though her career is defined more by individual project achievements than by exclusive recurring collaborations with specific directors or studios in anime. She is also known for her linguistic abilities, speaking English and Spanish, a skill she developed while living in Mexico for three years during her childhood.
