Mei Hata is a Japanese performer primarily known for her work as a live-action actress rather than a dedicated anime voice actor. She was born on April 10, 2002, in Tokyo, Japan. Standing 152 centimeters tall with blood type O, Hata began her entertainment career at a very young age, starting her professional activities when she was just one year old. She is affiliated with the talent agency Ken-On.

In her live-action career, Hata has amassed an extensive list of credits across film and television. She began appearing in dramas as a child actor, with early roles in productions such as the historical drama Seppuku Blue Sky in 2012 and the legal drama 99.9: Criminal Lawyer in 2016. She continued to build her filmography through the 2010s and 2020s with roles in series like The Maidens of the Savage Season in 2020, the romantic comedy film In Spite of Everything, Chihiro-kun is Too Sweet in 2023, and the live-action adaptation of the comedy series Joshi Kōsei no Mudazukai.

Hata is specifically known for the role of Saku Loli Momoi in the 2020 live-action television series Joshi Kōsei no Mudazukai, also known as Wasteful Days of High School Girls. In this adaptation of the manga by Bino, she played a character who pretends to be more experienced than she is to avoid being looked down upon by her peers.

While voice acting is not the primary focus of her career, Mei Hata has taken on roles in animation as a guest performer. Her most notable anime voice credit is the role of Minato Tateoki in the feature film Detective Conan: Highway no Datenshi, also known as Detective Conan: Fallen Angel of the Highway. This film is the twenty-ninth entry in the long-running Detective Conan movie series and was released in Japan on April 10, 2026. In this film, she voices Minato Tateoki, a twenty-two-year-old female police officer with the Kanagawa Prefectural Police who is assigned to investigate a motorcycle accident at Lake Tanzawa. This role represents a guest voice appearance for Hata, capitalizing on her acting experience rather than a recurring career as a voice specialist.
