Ayumi Kinoshita is a Japanese actress and voice actress born on December 13, 1982. While she is primarily known for her extensive live-action roles, particularly in tokusatsu superhero productions, she has also contributed her voice to several animated projects. Her career began in the early 2000s, and she gained widespread recognition for her portrayal of Marika Reimon, also known as Jasmine, the Deka Yellow ranger in the 2004 Super Sentai series Tokusou Sentai Dekaranger.

In the realm of anime voice acting, Kinoshita is best known for her role as Aki Izayoi, the main heroine in the Yu-Gi-Oh! 5D's television series. She began voicing this character in 2008, marking her first leading role in animation. This was not her first experience with voice acting, as she had previously provided voices for the series Tsubasa: Reservoir Chronicle and Glass Mask in 2005. She reprised the role of Aki Izayoi for the 2010 theatrical film Yu-Gi-Oh! 3D: Bonds Beyond Time, which brought together protagonists from different generations of the Yu-Gi-Oh! anime franchise. Beyond the Yu-Gi-Oh! franchise, her other notable voice roles include Zhalia Moon in the Japanese dub of the animated series Huntik: Secrets & Seekers.

Kinoshita's work in voice acting is closely tied to her on-screen career, with many of her voice roles appearing in projects related to the tokusatsu and anime genres she is associated with. For instance, she has provided voices for characters in films like Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z and Ressha Sentai ToQger vs. Kyoryuger: The Movie, which are extensions of her live-action work. While her filmography includes several anime and dubbed roles, her voice acting credits are relatively few compared to her extensive live-action appearances. Her performance as Aki Izayoi, however, remains a significant and recognized part of her career portfolio.
