About Satoshi
Satoshi Hino (日野 聡, Hino Satoshi) is an American-born Japanese voice actor who has been active in the industry since 2000. Born in San Francisco, California, he moved to Tokyo at the age of five, where he would eventually build one of the most prolific careers in anime voice acting. He originally pursued stage acting as a teenager, participating in a Children’s Theater Company before shifting his focus to voice work after taking part in the dubbing of the American television drama ER. He is currently represented by the talent agency Axl-One.
Hino is known for his ability to portray characters with deep conviction and powerful presence. His voice carries a natural authority that suits heroic and intense characters particularly well, making him a fitting choice for Kyojuro Rengoku — a man whose every word rings with passion and unwavering resolve. Hino’s performance in Demon Slayer is widely regarded as one of his most memorable, translating Rengoku’s fierce warmth into something genuinely moving, especially during the film’s climactic sequences.
Beyond anime, Hino has contributed his voice to video games, dubbing, and narration work across a long and varied career. He holds a first dan ranking in kendo, a detail that perhaps lends an authentic physical understanding to the many swordsmen and warriors he has voiced over the years. In January 2015, he announced that he had married fellow voice actress Saki Nakajima, and the couple welcomed their second child in September 2020.
