is a Japanese voice actress affiliated with 81 Produce.
She is most famously known for her role as the titular character of the Trotting Hamtaro television anime series.
Other notable voice roles of hers are as U-tan in Inai Inai Baa! and Leo in One Piece.
Biography In her elementary school graduation yearbook, she wrote down that her dream was to become a voice actor, but in part to her introverted personality, that glamorous dream was gradually pushed to the back of her mind around junior high school. After graduating from Shiga Prefectural Yasu High School, she moved from Shiga to Tokyo and enrolled in a vocational school. Two years then passed, she lived day by day without any particular goal, and just as she started to think, "Should I go back to Yasu?," she then found herself asking, "What on earth do I really want to do?" and "Is this really how I want to live my one and only life?" She then set her mind at that moment to "challenge the dream I had put away," and enrolled in the Baobab Academy, now known as the Visual Space Actor Training Institute, as a 9th-generation student. She wound up studying acting and methods of expression for four years.
In her third year after graduating the institute, Mamiya was officially selected to voice the titular character, Hamtaro, in the Trotting Hamtaro television anime series. According to a 2003 interview, she felt a sense of fulfillment when children told her, "Even when I'm feeling down, hearing Hamtaro's voice cheers me up."
She was formerly affiliated with Production Baobab until transferring to 81 Produce on April 1, 2004.
Personality Her vocal range is soprano『日本音声製作者名鑑2007』(in Japanese). Published by Shogakukan on March 25, 2007. p. 240. . and she speaks in the Kansai dialect.
Her hobbies and special skills include playing badminton, performing impersonations, playing the ukulele, and watching movies.
She had felt a complex about her own voice for a long time, as in junior high school, people around her would say things like "you're so strange" or "that's weird", making her want to overcome and gain confidence in herself. After debuting as a voice actress, she stated, "This voice is something only I can produce—it's my own uniqueness."
As a voice actress, she is mainly active in television animation and foreign film dubbing.
