Biography
Hideaki Matsuoka, credited in Japanese as 松岡秀明 and sometimes under the alternate spelling 松岡英明, is a Japanese animator born in Tokyo who grew up in Fukuoka and Oita prefectures [1]. His profile lists more than 400 animation credits spanning multiple decades, across television series and theatrical films in nearly every genre [1]. His animation-director work includes episodes of Attack on Titan: The Final Season, Banana Fish, Kakegurui, Garo: Vanishing Line, and Granblue Fantasy the Animation, while his key-animation credits reach into Death Note, Fullmetal Alchemist: Brotherhood, Naoki Urasawa's Monster, JoJo's Bizarre Adventure, and Space Dandy [1]. That range, mecha, psychological thriller, gambling drama, dark fantasy, says less about a single specialty than about a career built on being reliably good across very different house styles rather than tied to one genre. Off the job, his listed hobby is guitar [1], a small personal detail that stands out against a resume built almost entirely from studio credit lists rather than interviews or public profiles.
