Gou Aoba is a Japanese actor and voice actor born on October 19, 1969, in Yamagata Prefecture. He began his career on stage and eventually joined the Theatre Company Gekidan Seinenza. His early voice acting work in the late 1990s and 2000s includes roles in several notable anime series and films.

Aoba's career includes a range of roles in anime television series. He is known for his performances in mecha anime, such as his role as Guin Sard Lineford in Turn A Gundam and as Jonathan Glenn in Brain Powerd. He also voiced Armbrust in the Kiddy Grade series, a role he reprised in multiple films. In mystery series, he provided voices for Sota Murakami in the 1999 Kindaichi Case Files television series and appeared in multiple episodes of Case Closed. A significant role in a drama series was as Dr. Amakasu in Kita e: Diamond Dust Drops. His film work includes a part in the acclaimed 2004 movie Innocence: Ghost in the Shell 2.

Throughout his career in the late 1990s and early 2000s, Aoba frequently collaborated with director Yoshiyuki Tomino, appearing in Brain Powerd and both the Turn A Gundam television series and its subsequent films. He also worked alongside fellow voice actors such as朴璐美 (Park Romi) and 田中敦子 (Tanaka Atsuko) on multiple projects.

A significant development in Aoba's career was his transition to the theatre company Shiki, also known as Theatre Four Seasons. Due to this company's policy of exclusive involvement, he effectively suspended his voice acting activities. As a result, several of his notable anime roles were taken over by other voice actors in later projects and video games, including 平川大輔 (Hirakawa Daisuke) and 浅沼晋太郎 (Asanuma Shintaro).
