Although he initially planned to study music professionally at Musashino Academia Musicae in Tokyo, financial challenges prevented him from enrolling—steering him toward acting instead.

Career

After relocating to Tokyo, Watanabe joined the renowned En theatre troupe. His breakout stage role came in Shimodani Mannencho Monogatari, which introduced him to critics and audiences as a promising new talent.
