Shintaro Asanuma (浅沼 晋太郎), born January 5, 1976, is a Japanese voice actor and singer from Morioka, Japan whose career bridges anime performance and music. Known for expressive delivery and a flexible vocal presence, he has worked across character roles in anime and other media while maintaining a clear identity as a musical performer.
Within the wider seiyuu scene, Asanuma is valued not only for spoken roles but also for songs, character music, and related projects. That dual profile makes him especially relevant to anime music listeners, because his work connects the narrative side of anime with the performance and sound side of the industry. Voice acting in Japan often requires careful characterization, emotional control, and the ability to adapt to different casts, tones, and dramatic settings, and Asanuma's career reflects that range.
His singing activity adds further depth to his public profile, and his place in the broader seiyuu-singer landscape helps define his appeal. Artists in this space contribute to anime through voice work, theme-related music, and character-driven expression, and Shintaro Asanuma fits that tradition well. He stands out as a performer whose work can be approached through both acting and music, embodying the crossover that continues to shape how fans discover Japanese artists and how anime music databases present performers.
