Today the two men took part in their weigh in for the bout and both fighters came in on the divisional limit of 118lbs, and both looked in good shape, showing off ripped bodies.
At the weigh in Yamanaka admitted his body was getting bigger but that he was able to fine tune things for this bout, which will be his 13th world title defense. A win for Yamanaka will see him tying the long standing Japanese record for most defenses of a world title, set at 13 defenses by Yoko Gushiken.
As for Nery his comments to the media was about his ability to put weight back on and he's stated that he will put on around 18lbs between this morning's weigh in and fight time, essentially making him a Lightweight in the ring. From what we understand that sort of a weight increase is normal from Nery but does seem a huge amount for a fighter who has mentioned moving down to Super Flyweight in recent dats.
For fans who aren'taware, the contest will be aired at 19:56 on NTV live in Japan.
