Yasuhiro Mamiya is a Japanese voice actor, born in 1981, who plays Boiled, the formidable assassin from Sakamoto's past, in the original Japanese version of Sakamoto Days.
Mamiya voices Boiled, an assassin with deep ties to Taro Sakamoto dating back to their days together at the JCC training academy. Operating by a personal code that spares anyone but the assigned target, Boiled favors explosives in combat and stands as one of the series' most dangerous returning threats.
Mamiya, who is represented by Kenyū Office, has built a career largely around imposing, older-skewing characters thanks to his deep tenor voice, including Magma in Dr. Stone, Iron Michael in Baki Hanma, and the giant Gigantomachia in My Hero Academia. He is also known for his skill at mimicking the voices of veteran actors such as Hōchū Ōtsuka and Banjō Ginga.
