Kokoro Noda is a Japanese actress, soprano singer, and voice actor born on September 26, 1992, in Fukuoka Prefecture, Japan. Her career began in musical theater at a young age, and she has since built a diverse portfolio spanning stage productions, television, and anime voice work.

Noda's entry into the entertainment industry came through stage performance. She made her professional debut in 2002 at the age of ten, playing the role of Young Nala in the Fukuoka production of the musical The Lion King. This early start in a major theatrical production laid the foundation for a career that would blend performance with her formal musical training. She later graduated at the top of her class from the Ferris University Faculty of Music, where she specialized in vocal music, and completed a master's degree in the same field at the university's graduate school. Her classical training as a soprano has been a significant part of her professional identity, leading to appearances in classical music concerts and performances at settings like nurseries and kindergartens. She has also been a member of the choir unit Ferris Frauenchor.

In addition to her early work in The Lion King, Noda's stage career includes a variety of roles. She starred as the title character in the 2017 stage play Otome Youkai Zakuro. She has also been a regular performer in the Daisuke Ooyama no Sekai Meisaku Gekijou series from 2017 to 2020 and has appeared in reading musicals and other stage productions.

Noda's voice acting roles in anime, while a facet of her career, are documented alongside her broader performance work. She provided the voice for the lead role of Spring Pan in the anime film Sprin' Pan Let's go forward!, which was released in Japanese theaters on July 31, 2020. Her other anime credits include roles in the television series Rinshi!! Ekoda-chan in 2019 and Kintamani Dog in 2021. In the video game world, she has voiced characters in titles such as Mobile Legend and performed voice work for the game Sōkyū no Misuto Āku, for which she also contributed to the singing and lyrics.

Beyond acting and voice work, Noda has been a familiar face on Japanese television. From 2018 to 2022, she was a regular performer as "Kokoro Oneesan" on the Friday corner "Kin☆Moni" of the children's program Kinder TV. Her musical abilities have also led to appearances on music programs like THE Karaoke★Battle, and her academic background has seen her participate as a member of a "women's intellectual team" on the quiz show Nep League. Her work extends to commercials and narration for regional television programs, particularly in the Yamagata Prefecture area. In September 2020, Noda announced that she had joined the talent agency Yoshimoto Kogyo.
