Keisuke Fujita is a Japanese voice actor also known by the stage names Yoshinori Fujita and Keisuke Oda, the latter being his current professional name. Born on October 27, 1976, in Hirosaki, Aomori, Japan, he began his voice acting career in the late 1990s after training at the Tokyo Announce Gakuin. Throughout his career, he has worked with several agencies including Atelier Peach, Theater Sugoroku, Arts Vision, and Kenyu Office, from which he departed in September 2016. He is recognized for his versatile tenor voice and ability to perform both energetic, comedic roles and more serious, emotionally rich characters, as well as authentic Tsugaru dialect from his native Aomori region.

Fujita has built a substantial body of work in anime, video games, drama CDs, and dubbing. One of his most notable early roles is Kaoru Hitachiin, one of the Hitachiin twins, in the popular series Ouran High School Host Club. His other significant anime voice credits include Masumi Okuyama in Nodame Cantabile, Ginka Midarezaki in Kyōran Kazoku Nikki, Kyoumu Satomi in Asura Cryin', Isao Kako in Bokurano, Atsushi Hirata in Shinreigari, Hiroaki Ogata in Skip Beat!, and Alessandro XVIII in Trinity Blood. He also contributed to the Naruto franchise, voicing Taruho in the film Naruto Shippuden the Movie: The Will of Fire.

In addition to his television and film work, his voice acting portfolio extends to video games. He is known for voicing Skeleton-T in the Puyo Puyo series and Elbert Levin in the Wand of Fortune game series. He also took part in hosting radio shows, including the program VOICE CREW, and contributed vocal performances to character song CDs. While he is not widely noted for receiving formal industry awards, his consistent output of fan-favorite performances in prominent series has earned him a dedicated following.

He has a noted collaboration with the production team of the Puyo Puyo game series, providing the voice for the character Skeleton-T across multiple installments. His work on the Ouran High School Host Club also saw him performing alongside voice actors such as Mamoru Miyano as Tamaki Suoh and Maaya Sakamoto as Haruhi Fujioka. His professional name changes can cause some confusion, as early credits list him as Keisuke Fujita before he transitioned to using Keisuke Oda, his current name. His hobbies include painting and appreciating film art, with singing listed as a special skill. After leaving his final agency in 2016, several of his long-standing character roles were recast with other voice actors.
