The loss to Obara was Iwabuchi's second failed attempt to claim the OPBF title, with the first being a decision loss in an absolute barn burner with Min Wook Kim back in April 2013.
Despite those set backs the the explosive Iwabuchi seems to know that he still has a bright future in the sport and will return to the ring tomorrow to battle against Venezuelan fight Luis Araguayan (11-7, 6) in his comeback bout.
At today's weigh in Iwabuchi weighed in at the contracted limit for the fight, 140lbs, notably heavier than Araguayan who was 139¼lbs. Although heavier Iwabuchi looked sensational shape, as seen in the picture he posted on his blog yesterday.
Notably this is the weight that Iwabuchi tends to shine at. Whilst he has suffered a pair of notable losses he had also scored notable wins here, including an opening round stoppage of Shamgar Koichi a 10 round decision win over Tsuyoshi Ozawa and an 8th round stoppage of Valentine Hosokawa. As for Araguayan he'll actually be moving up in weight for the bout having made his name at Lightweight.
