Keitaro Hoshino: Boxing Career and Notable Fights
Keitaro Hoshino was a Japanese minimumweight boxer and two-time WBA world champion. He died in Naha, Okinawa, on October 9, 2021, aged 52.
Two WBA title reigns
Hoshino first won the WBA minimumweight title in December 2000 with a unanimous decision over Joma Gamboa. He lost the belt to Chana Porpaoin in his first defense in April 2001. In January 2002, he won the vacant title by defeating Gamboa again, then lost it to Noel Arambulet in July.
Hoshino later challenged José Antonio Aguirre for the WBC minimumweight title in 2003.
The two victories over Gamboa formed the foundation of Hoshino’s world championship record. Both were twelve-round decisions, but they came in different circumstances: the first removed a reigning titleholder, while the second settled a vacant championship. Returning to the top after losing to Porpaoin made Hoshino a two-time champion within a little more than a year.
His rivalry with Arambulet also produced two meetings. After the Venezuelan took the WBA belt in July 2002, Hoshino challenged him again in Osaka that December. Arambulet won another majority decision, preventing a third Hoshino reign. The following year’s WBC challenge against Aguirre extended his pursuit of a championship through another sanctioning organization.
Hoshino retired from professional competition in 2003. He later established a gym in Kakamigahara and remained involved in boxing there until 2018, according to the WBA’s retrospective. That work added a coaching and gym-building chapter to a career remembered most clearly for his two minimumweight title victories over Gamboa.
Further career results
Hoshino’s first title victory came in his native Yokohama, adding a local setting to the Gamboa result. After the ring, his work shifted to gym ownership in Kagamigahara. The WBA’s retrospective distinguishes his 2003 retirement as a boxer from his eventual departure from gym work in 2018, two separate endpoints in his involvement with the sport.
