Mewhan, also known by the Japanese name みゆはん, is a Japanese singer-songwriter and voice actress from Kagawa Prefecture who began her career in 2015. She is affiliated with the record company Victor Entertainment.

Her career is notably dual-faceted, combining music and voice acting. She made her independent debut in 2016 with the self-produced album "Johari no mado." Her major debut followed on February 22, 2017, with the mini-album "Jiko Schema" under Victor Entertainment. This album was significant as it included "Boku no Friend," the ending theme song for the anime series Kemono Friends, for which she also provided a voice.

Mewhan's voice acting roles are closely tied to the Kemono Friends franchise. Her most prominent role is Sand Cat in the first season of Kemono Friends in 2017. She later voiced Common Vampire Bat in Kemono Friends 2 in 2019 and also took on two roles in the Kemono Friends 3 project. Beyond this franchise, she voiced the role of Racehorse Owner's Daughter in the 2021 anime series Neko Jockey. While her acting credits are primarily associated with these works, her broader career is marked by extensive activity as a musician. She has released numerous albums and singles, composed theme songs for other anime such as SUPER SHIRO and Hachigatsu no Cinderella Nine, and even provided songwriting for the popular singer Ado.

While specific recurring collaborations in voice acting are not widely documented, she has worked with other artists in the music industry. Notably, she served as a producer for an album by singer Shiina Mikoto. In 2024, Mewhan announced her marriage and subsequently left her agency, CloudNine, leading to the closure of her official website and fan club.
