Akira Koga is a Japanese voice actor affiliated with the talent management firm Production Baobab. He was born in Saitama Prefecture on May 25, 1990. His path to voice acting began in childhood, where he enjoyed pretending to be heroes and other characters. Although he initially aspired to become an actor, he was inspired to pursue voice acting after frequently receiving compliments on his voice.

Koga has built a career through a wide range of supporting roles in anime, video games, and dubbed versions of foreign films and television dramas. In anime, he is known for providing the voice of Tatsuki Washio, the taciturn third-year middle blocker for Fukurōdani Academy, in the Haikyu!! series, including the Land vs. Air OVA and the To the Top season. His other anime credits include roles in long-running and popular series such as Silver Spoon, Food Wars! Shokugeki no Soma, Blade & Soul, and The Pilot's Love Song. He has also had guest roles in major franchises like Gintama., Baki, Boruto: Naruto Next Generations, and The Case Study of Vanitas. His work extends to web animations, including roles in SD Gundam World Sangoku Soketsuden and Cyberpunk: Edgerunners.

Beyond traditional animation, Koga's voice is featured in numerous video games, such as Granblue Fantasy and Fight League. He is also active in the field of audio dubbing for foreign content, providing Japanese voices for films and television series, including Chicago Fire and Bosch. His work as a narrator is heard in commercials for franchises like Zoids Wild and Beyblade.

A notable aspect of Koga's career is his role as the voice provider for Frimomen, a Japanese voice synthesis software. He provided the vocal source material for Frimomen's iterations as a pitagoe sound effects library, a VOICEPEAK text-to-speech engine, and a Synthesizer V AI singing synthesizer. This work places him at the intersection of traditional voice acting and emerging digital voice technologies.
