Biography
Kentaro has 2 younger brothers. He lived in Saitama before entering elementary school, then moved to Central Okinawa and lived there until he was 19-years-old.
As a child, Kentaro's aspirations frequently changed, ranging from becoming a soccer player and a school teacher to working as a staff member in a professional wrestling company. He first became aware of voice acting as a profession in the second year of middle school after accidentally watching a music video by Mamoru Miyano on TV, thinking, "This singer is wonderful!" At that time, he only occasionally watched anime and manga, unaware that voice acting was a profession. It was while watching Mamoru Miyano star in "Mobile Suit Gundam 00" that he noticed his name at the top of the credits, sparking an interest in voice acting as a career. This realization led him to think that becoming a voice actor might allow one to experience all the professions they had dreamed of, thereby making voice acting an appealing career choice.
After graduating from Sogo Gakuen Human Academy in 2014, he entered the Haikyo Voice acting Studio. In 2015, he started working at Tokyo Actor's Consumer's Cooperative Society.
His hobbies are soccer, watching professional wrestling, watching baseball, reading and collecting manga. Due to his interest in professional wrestling, he was invited as a guest speaker at DDT Pro-Wrestling in 2021 and 2024.
