Masaki Kitahara is a Japanese actor and voice actor born on July 15, 1976, in Osaka Prefecture, Japan. His career has primarily focused on live-action television dramas and films, with a comparatively limited number of confirmed roles in anime voice acting.

While Kitahara has an extensive list of acting credits spanning from the mid-1990s to the 2010s, verifiable information regarding his work as an anime voice actor is sparse. His most frequently cited role as a voice actor is Keima Oimachi in the anime series Dr. Rin ni Kiitemite! which was released in 2001.

The role of Shingo Obata in the series Shota no Sushi is a live-action television drama role rather than an anime voice acting role. The series, which aired in 1996, is a comedy based on a manga about a young sushi chef, and Kitahara appears as an actor in the supporting cast alongside other live-action performers. This distinction between his live-action and voice work is a key aspect of his professional profile.

Across various film and television databases, Kitahara is overwhelmingly listed as an actor, with only a single title categorised as an anime voice performance. His other notable acting credits include appearances in popular Japanese dramas such as Hoshi no Kinka, Miseinen, Virgin Road, and the film Kamen Rider Hibiki to 7-nin no Senki. Due to the limited number of confirmed anime roles, a comprehensive profile focusing exclusively on his voice acting career cannot be provided.
