Hiroto Kyoguchi: Two-Division World Champion

Hiroto Kyoguchi is a Japanese former professional boxer from Izumi, Osaka. He won world titles at minimumweight and light flyweight before moving up to flyweight late in his career. Born on November 27, 1993, he retired in 2025 after a nine-year professional career.

A Meteoric Rise to Stardom

Kyoguchi’s professional career began in 2016, and it didn’t take long for him to make a lasting impression. With a relentless offensive style and a penchant for delivering devastating knockouts, he quickly climbed the ranks of the minimumweight division. In 2017, he captured the IBF minimumweight title, solidifying his status as a force to be reckoned with.

Conquering New Heights

Not content with his minimumweight reign, Kyoguchi set his sights on the light flyweight division. In 2018, he dethroned Hekkie Budler to claim the WBA and The Ring light flyweight titles, cementing his place among the elite fighters in the sport. His reign as a two-weight world champion was evidence of his versatility and unwavering determination.

A Warrior’s Spirit

Kyoguchi won world titles at minimumweight and light flyweight. At minimumweight, he made two successful defenses before moving up to challenge Hekkie Budler for the WBA light-flyweight title in 2018.

Kyoguchi’s light-flyweight reign ended when Kenshiro Teraji stopped him in November 2022. After moving to flyweight, he lost a decision to Jonathan González in March 2024 and returned with a decision win over Ricardo Astuvilca that October. He then challenged WBO flyweight champion Anthony Olascuaga on March 13, 2025, losing by unanimous decision. Kyoguchi announced his retirement in July 2025.
