Since Tokyo Twilight Ghost Hunters, some of his more prominent roles include Nishiki Sasa in Love Kome, Ritsu Shikishima in Caligula, and Taiga in Tribe Nine.
[1][2] Chiharu is the younger brother of voice actress Miyuki Sawashiro.
At first, Chiharu was a bit skeptical of voice acting, since it was a lot less popular at the time.
However, as voice acting got more popular, his peers continued to ask him questions about his sister.
Using connections from his sister, he was able to enter vocational school and eventually made his full debut as a voice actor with Masamuse Shiga in Tokyo Twilight Ghost Hunters.
