Tomoe Tamiyasu is a Japanese voice actor and singer born on January 3 in Hiroshima Prefecture, Japan. She debuted in 2005 and has built a prolific career, primarily known for her extensive work in adult visual novels and games, having been cast in over two hundred titles. For her voice acting in all-ages anime and general audience games, she typically uses the name Tomoe Tamiyasu written in the hiragana script as たみやすともえ, a practice she began in 2011 to distinguish her mainstream work from her adult-oriented roles, which are credited under her name written in kanji as 民安ともえ.

Her career is marked by several prominent and recurring roles. She is widely recognized for voicing the character Rin Natsume, first in the Key visual novel Little Busters! and its adult version Ecstasy, and later in the 2012 and 2013 television anime adaptations Little Busters! and Little Busters! ~Refrain~. This longstanding association with the character continued with her reprisal of Rin Natsume in the 2021 anime crossover series Kaginado and the Kud Wafter adaptation. Another significant role is that of Irisu Makina in the Grisaia series, which includes the anime The Fruit of Grisaia, The Labyrinth of Grisaia, and The Eden of Grisaia, as well as the original adult games. She also voiced Nagisa Hanamiya in the 2014 anime In Search of the Lost Future.

In addition to these widely-known roles, the examples cited are consistent with her career profile. She plays Ayane Shirakawa in the 2020 anime Overflow and Futami Moriyama, a teacher, across all three seasons of the Recorder and Randsell (Recorder to Randoseru) anime series that aired in 2012 and 2013. She also provided the voice for Kotori Hoshino in the 2012 adult OVA series Tsugou no Yoi Sexfriend?.

Her work is not limited to these series. Tamiyasu has voiced numerous characters in other notable projects, such as Mishima in the 2015 original anime Charlotte and a minor role as a TV audio voice in the 2022 hit series My Dress-Up Darling. In the realm of video games, her extensive filmography includes roles in major franchises, with performances in Yakuza: Like a Dragon as Kamulop and Narumi Yu, and as various characters in the long-running La Pucelle series.

Beyond voice acting, Tamiyasu is also an active singer, having released six albums since starting her singing career in 2006, and has performed theme songs for games. Her voice work has extended to narration for cultural broadcasts and hosting several radio shows. In 2018, she expanded her artistic presence by debuting as a virtual YouTuber under the name Tammy. She was previously affiliated with the talent agency Rock'n' Banana Actors but has been working as a freelancer since 2021.
