The bout, which is for the title given up earlier this year by Yu Kimura, hasn't yet been officially announced but all of sources have "all but confirmed" that the contest is set with a date, venue and show and will almost certainly be announced over the coming days.
We've known for a short while that the two men would meet for the title, with Ono being guaranteed a shot after Kimura gave the belt up. Horikawa on the other hand booked his place in the contest just over a week ago, when he stopped compatriot Il Che in the 8th round of their clash. What we hadn't expected was such a quick turn around from Horikawa who would be going in to this tough bout just over 8 weeks after the Che contest.
For Ono this will be a chance to claim a second professional title, having previously held the OPBF Light Flyweight title. As for Horikawa this is his 4th shot at a Japanese title, having previously come up short against Akira Yaegashi in 2009, Ryuji Hara in 2012 and Yu Kimura in 2014, amazingly however he is 0-6 in title fights coming in to this bout
From we understand the bout is to take place at the Korakuen Hall on Dangan 139 and will be on the same show as the upcoming return of former Japanese Bantamweight champion Kentaro Masuda (21-7, 11), who will be facing Wataru Miyasaka (9-3-1, 2).
