Yoshimasa Hosoya is a Japanese voice actor and narrator known for a deep, flexible voice that has made him a frequent choice for athletes, soldiers, complicated rivals and emotionally guarded protagonists in anime, games and dubbing. Born on February 10, 1982, in Onomichi, Hiroshima, Japan, he trained for voice work at Tokyo Announce Gakuin Performing Arts College and through the Mausu Promotion Actor Training Center. He joined Mausu Promotion, later left the agency, and has worked as a freelancer since 2014.
Hosoya's early career included small roles across television animation before he began to receive larger parts in the late 2000s and early 2010s. One of his major breakthrough roles was Shichika Yasuri in Katanagatari, a stylized adaptation that required both comic restraint and gradual emotional awakening. Around the same period, he voiced Kuranosuke Shiraishi in The Prince of Tennis franchise and Junpei Hyūga in Kuroko's Basketball, helping establish him in sports anime. His performance as Sentarō Kawabuchi in Kids on the Slope also showed a warmer, more naturalistic side, fitting a series built around jazz, friendship and adolescent longing.
International anime audiences often know Hosoya for Reiner Braun in Attack on Titan. The role demanded a balance of physical confidence, buried conflict and psychological fracture as the series revealed more about Reiner's identity and loyalties. Hosoya also voiced Asahi Azumane in Haikyu!!, giving the Karasuno wing spiker a gentle, anxious strength; Fumikage Tokoyami in My Hero Academia, whose formal speech and shadow power made him one of Class 1-A's most distinctive students; and Doppo Kunikida in Bungo Stray Dogs, where he brought rigidity, impatience and loyalty to an idealistic detective.

His credits extend across science fiction, fantasy, action and game franchises. He voiced Orga Itsuka in Mobile Suit Gundam: Iron-Blooded Orphans, Daryun in The Heroic Legend of Arslan, Genjirō Tanigaki in Golden Kamuy, Joe in Megalobox, Shin in Dorohedoro and roles in Chihayafuru, Strike the Blood, Terra Formars and Space Battleship Yamato 2199. In games, he has been associated with Belial in Granblue Fantasy and Welt Yang in Honkai Impact 3rd and Honkai: Star Rail. He has also appeared in anime films including In This Corner of the World and The Empire of Corpses.
Hosoya has been recognized by the Seiyu Awards, winning Best Supporting Actor honors at both the 8th and 10th ceremonies. In 2017 he took a temporary hiatus for throat treatment, a significant event for a performer whose career depends on vocal stamina and control. He resumed work later that year. In 2025 he publicly announced that he had married someone outside the entertainment industry.
What distinguishes Hosoya's work is not only vocal depth but the ability to make strong characters sound vulnerable without weakening them. His heroes and rivals often carry pressure: team expectations, military command, hidden guilt, private ideals or fear of failure. That quality has made him especially effective in ensemble anime where characters need to be memorable quickly but deepen over time. Across sports series, shonen action, literary fantasy, prestige animation and games, he has become one of the widely recognized male voice actors of his generation.
