Miyari Nemoto is a Japanese voice actor from Ibaraki Prefecture, born on May 22. She is affiliated with the talent agency Aoni Production. Her path to voice acting began in childhood, fostered by a father who shared his recordings of anime and movies with her. Although she admired anime characters, she initially did not pursue acting, instead aiming to become a kindergarten teacher while attending university in Tokyo. It was during this time that encouragement from a university lecturer led her to reconsider, and she enrolled in the Tohokushinsha Eizo Techno Academia voice acting department alongside her regular studies.

Her professional career started in 2019, with her anime debut in a minor role in the series GeGeGe no Kitarō. The early years of her career were filled with small roles in major franchises such as One Piece, Attack on Titan, and Fruits Basket. A significant turning point came in 2022 when she was cast in her first main role as Sazanka in the anime In the Heart of Kunoichi Tsubaki. This role was pivotal for Nemoto, who had previously set a personal goal to leave the industry if she had not secured a satisfactory role within five years. She also took on the role of Nodoka Takahata in Alice Gear Aegis Expansion in 2023, a character she later noted felt very close to her own personality.

In 2025, Nemoto was cast in several prominent roles, demonstrating her growing presence in the industry. She voices the title character, Ruri Tanigawa, in the anime adaptation of Introduction to Mineralogy, also known as Ruri Rocks. She also plays Ayumi Endo in Honey Lemon Soda and Piisuke in Sakamoto Days. Beyond these, her filmography includes roles in Classroom for Heroes as Levia, Ippon Again! as Nene Koide, and The Duke of Death and His Maid as Fifa.

Nemoto is also active in video game voice work. Her roles include Chie Sugawara in Heaven Burns Red, Reisa Uzawa in Blue Archive, and Samson Big in Uma Musume Pretty Derby. She has also lent her voice to web anime projects such as Pokémon Evolutions and Pluto. Her hobbies include running and nail art, and she possesses practical skills in playing the electric bass and skiing. She is also a practitioner of judo, holding the rank of shodan.
