To get Obara rounds his team matches him with Kota Oguchi, a team tough opponent who hadn't been stopped in 16 previous contests. He was viewed as a safe opponent due to his lack of power and limitations as a fighter but he was durable, he was tough and he knew how to survive having gone 8 rounds numerous times.
What Obara's team wouldn't have expected was for their charge to drop Oguchi in the second round or finish him off in round 3 in what was genuine a very impressive result despite not looking it on paper. On paper Obara had beaten a guy who had entered 8-8, in actuality he had stopped one of the toughest "journeymen" in Japanese boxing in just 3 rounds!
Since this bout Obara has become one of the best Light Welterweights in Asia. He has won Japanese and OPBF titles and become one of the most dangerous punchers in or around 140lbs. Oguchi on the other hand has fought 5 times, losing 4 of those 5 bouts though has gone the distance in all 4 of those losses.
