We saw two such fighters testing their credentials at one of the B class tournament finals last year when then unbeaten Naoto Uebayashi, a former amateur star, battled the 22 year old Yusaku Kuga. Kuga, who came into the bout with a loss and a draw from his previous 8 bouts knew he was up against it but also showed true self belief and refused to be intimidated by the amateur credentials and hype that Uebayashi had gotten. As a result we got a fantastic fight between two very good and promising fighters.
The fight was a very competitive one that showed off what both fighters were capable of at time. Since then however both appear to have developed their skills notably and we'd not be shocked if one, or the other, manages to claim at least a national title at some point in their career.
