Yoshihiro Kamegai is a retired Japanese professional boxer who competed primarily in the welterweight and junior middleweight divisions. Born on November 12, 1982, in Sapporo, Hokkaido, Japan, Kamegai fought out of Tokyo and stood 5 feet 9 inches tall with a reach of 70.9 inches. He was known for his orthodox stance and was affiliated with Teiken Boxing Gym, later fighting under Golden Boy Promotions during his career abroad. Kamegai began his professional career on November 5, 2005. His early years were mostly spent fighting in Japan, where he quickly rose through domestic ranks, ultimately capturing the Japanese light-welterweight title in 2010 and defending it once before vacating. In 2013, he won the OPBF welterweight championship, again vacating after a successful defence to concentrate on fighting internationally. By 2011, Kamegai had made his U.S. debut with a victory over Hector Munoz at MGM Grand, developing a reputation for thrilling contests and durability.

During his peak years, Kamegai faced several notable opponents and gained recognition for his exciting, pressure-based fighting style. He fought for a world title on August 26, 2017, challenging Miguel Cotto for the vacant WBO junior middleweight championship at the StubHub Center in Carson, California. Though defeated by unanimous decision, the bout highlighted Kamegai’s resilience and relentless offence against one of boxing’s biggest stars. Other significant fights in his career included high-action wars with Robert Guerrero, Alfonso Gomez, and Jesus Soto Karass, all in the United States. Kamegai’s contests were distinguished by heavy exchanges, with Guerrero and Cotto both acknowledging his durability and non-stop aggression after their respective bouts.

Over a professional career spanning nearly 13 years, Kamegai compiled a record of 27 wins, 5 losses, and 2 draws, with 24 wins coming by knockout. He was never stopped in any of his defeats, earning a reputation for toughness and an excellent chin. In total, he fought 10 times in the United States, including his final four bouts, which brought him international acclaim as a fan-favourite action fighter.

Kamegai retired after his last professional fight on August 17, 2018. Throughout his career, he was respected for his all-action style, resilience, and willingness to face elite-level opposition. His bouts were frequently marked by aggressive forward movement and high punch volume, contributing to his status in Japan and abroad as a reliable and entertaining combatant within the welterweight and junior middleweight divisions.
