Biography
Initially, he wanted to be an actor, but since he was from Hiroshima Prefecture, even if he wanted to become an actor, there were no auditions and he was not in an environment where he could move to Tokyo. After entering high school, he made many friends, got deeply involved in anime and manga, and thought that a career as a voice actor might be interesting, which led to him aiming to become a voice actor.

After graduating from high school, he enrolled in Amusement Media Academy. After he debuted in dubbing in The Good Doctor in 2012 during his time at the school, he passed the "Internal Audition for Production Affiliation" held from January to March 2013 at the Office Osawa. In October of the same year, he made his first starring role as Takahiro Mizuno in the TV anime Walkure Romanze.
