Biography Early life Koga was born in Saga Prefecture on August 24, 1993. She had an interest in anime since her childhood, watching series such as Cardcaptor Sakura and Ojamajo Doremi. She was first introduced to voice acting while watching the children's television program Okaasan to Issho and becoming fond of the puppet segments featured in the show. This inspired her desire to "become friends with dolls", which along with her interest in anime, influenced her decision to pursue a career in entertainment. She ultimately decided to pursue a career in voice acting after learning about the profession featured in a program she watched.
Koga joined her school's softball club while in junior high, and later the light music club in high school. When growing up, she experienced a sense of embarrassment regarding her interest in anime among her peers. Coupled with her shy personality and difficulties expressing herself in public, she initially concealed from others her career aspiration in voice acting. Even if some would ask her if she wanted to be a voice actress, she would instead reply about wanting to become a hairdresser or pet groomer instead.
Acting career After informing her family about her plans to pursue voice acting, Koga felt discouraged as she would require moving to Tokyo for work, which she did not view as practical at the time. Upon her parents' suggestion, she began taking acting lessons at a vocational school in Fukuoka. After completing her training, she enrolled in the training school of 81 Produce, a voice acting agency, on the recommendation of a teacher and became affiliated with the company upon graduation.
Koga's first credited role in an anime was a woman in Rokka: Braves of the Six Flowers. In 2017, she was cast as the character Sora Kaneshiro in Angel's 3Piece!; she also became part of the band Baby's Breath along with Yūko Ōno and Yurika Endō, her co-stars in the series. She was later cast as Yuri Miyata in Two Car, where she performed the series' ending theme "Angelica Wind" together with her co-star Aimi Tanaka.
In 2019, Koga played the role of Kaguya Shinomiya in Kaguya-sama: Love Is War, for which she won Best Actress in a Leading Role at the 14th Seiyu Awards. She also made a cameo as a movie theater employee in the live-action film adaptation of Kaguya-sama: Love is War. In 2020, she was cast as the Japanese voice of Paimon in the mobile game Genshin Impact. In 2021, she voiced Shouko Komi in Komi Can't Communicate and Aki Shino in Remake Our Life!. In 2023, she played Konoha Akisato in the anime television series 16bit Sensation: Another Layer; she also performed the series' ending theme "Link: Past and Future". Koga has won Best Voice Actress twice at the Newtype Anime Awards.
Personal life Koga has an older brother with whom she used to fight in judo. She has an interest in manhole covers, finding it interesting how they can come in different shapes and have different characters on them. Koga can also play the drums, which she learned while in junior high school.
