"I thought the world (title) was way off in the distance but now I am in a position where I have to aim for it," said Obara, the super fly champion in the Oriental and Pacific Boxing Federation.
"I want to seize this chance with a win (against Castillo)," the 28-year-old from Iwate Prefecture told a press conference in Tokyo.
