Early Career
Kenshiro Teraji began his boxing journey at a young age, influenced by his father’s career. He enjoyed a successful amateur stint while attending Kansai University, where he refined the technical skills that would later define his professional style.
Unlike many boxers who turn pro as teenagers, Teraji completed his education and built a solid foundation before entering the paid ranks.
He made his professional debut in August 2014, winning a six-round decision. His rise was rapid; within his first year, he claimed the WBC Youth title.
By his eighth fight, he had already captured the Japanese national title and the OPBF light flyweight belt, proving he was ready for the world stage far sooner than most critics expected.
Professional Career
Teraji’s career is defined by his long reign as the WBC Light Flyweight Champion. He won the title in 2017 against Ganigan López and defended it eight times before a shock stoppage loss to Masamichi Yabuki in 2021.
