Tomoki, along with older brother and trainer Koki Kameda [亀田 興毅], were particularly interested in the bout as Tomoki was ranked #3 by the WBA, only behind Moises Flores and Roman himself.
After the fight Tomoki admitted that he wanted Kubo to win, as an all-Japanese title bout did excite him, but he's happy to fight Roman and is confident of beating the new champion if he becomes the mandatory for the WBA title. He is however in no rush to announce his next fight as he's got an eye on the upcoming IBF title fight between defending champion Yukinori Oguni's (19-1-1, 7) [小國 以載] and mandatory challenger Ryosuke Iwasa (23-2, 15) [岩佐 亮佑], which would give Tomoki an all-Japanese title bout.
As for Roman he himself stated that he was happy to return to Japan to defend his newly won title as long as certain conditions were met, presumably finances would be the key. Not only is he happy to face anyone but also do a rematch with Kubo if the former champion wants a rematch, which after today's fight he won't be in a rush for.
It should be noted Tomoki won't be the only Japanese fighter looking at Roman as a potential foe with Shingo Wake (21-5-2, 13) [和氣 慎吾], Yusaku Kuga (15-2-1, 10) [久我 勇作], and Hidenori Otake (29-2-3, 13) [大竹 秀典] and Hinata Maruta (5-0, 4) [丸田 陽七太], who face off in October, all likely looking for a world title bout in the near future.
