Himari Mochida is a Japanese voice actress from Tokyo, born on August 7, 1993. She is affiliated with the talent agency 81 Produce. Before adopting her current stage name in July 2017, she was known by her birth name, Yumi Nagata.

Mochida's path to a voice acting career began after she watched the anime Hunter x Hunter, which made her aware of the profession. Initially thinking her own voice was too ordinary to become a voice actor, this very thought sparked her interest and motivated her to pursue it. She is a graduate of the AMUSEMENT MEDIA综合学院. Her talent was recognized early on when she won the Special Award, the Cultural Broadcasting Award, and the Shogakukan Award at the 7th 81 Audition. She joined 81 Produce in April 2015.

Mochida has built a career through a wide variety of supporting roles in anime, video games, and dubbed foreign media. One of her earliest major recurring roles is as望月愛美 (Mochizuki Manami) in the multimedia project and game 青空Under Girls！. In anime, her versatility is evident through roles such as Mitsuo Seta in an episode of the long-running series Detective Conan and as a high school girl in the romantic comedy Horimiya. She has also appeared in popular series like Kaguya-sama: Love Is War as a schoolgirl, Laid-Back Camp as a wagashi shop clerk, and as Suzu in the sports anime Ahiru no Sora. Her work in the 2017 original net animation Precarious Woman Executive Miss Black General, where she voiced the role of Secretary, stands as a specific example of her anime credits from that period.

Beyond anime, Mochida has an extensive portfolio in video games. She is the voice of the character望月愛美 in 青空Under Girls！ and has contributed to major titles such as Final Fantasy VII Remake as Sara and Monster Strike as one of the Brothers Grimm, Jacob. Her game credits also include roles in Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka ~Memoria・Freese~, White Cat Tennis, and Quiz RPG: The World of Mystic Wiz. Her work in foreign dubbing is equally prolific, lending her voice to characters in films and television series like The Nutcracker and the Four Realms, The Matrix Resurrections, and the Korean drama The Uncanny Counter, as well as animation such as Thomas & Friends and Toy Story 4.

In addition to on-screen roles, Mochida's work includes performances in drama CDs, narrations for television programs, and audio books. She has also served as a radio personality for programs like 優美・祐太のまっすぐなラジオ. Her hobbies and skills include dancing, badminton, and hair arranging.
