Tomomi Motoyama is a Japanese voice actor known for work in anime and adult visual novel adaptations. Information about her career is sparse, with her most notable confirmed role being in the early 2000s OVA series Canvas - Sepia-iro no Motif.

In that production, Motoyama provided the voice for the character Yuzu Nanashiro. Yuzu is a second-year student at Nadeshiko Academy and a member of the track and field club, characterized by her energetic personality and small stature. The two-episode OVA, released from December 2001 to March 2002, was based on the adult visual novel of the same name developed by Cocktail Soft. The character Yuzu Nanashiro was one of the main heroines in the original game, with her specific scenario written by Daisuke Tonoike and her character design by Tatsuya Kurusu.

Outside of this role, no widely available or verifiable information exists concerning other significant voice acting credits, recurring collaborations with directors or studios, or notable awards or achievements in her career. The lack of a substantial public profile suggests that voice acting may not have been a primary or long-term focus of her professional activities.
