Today, ahead of that bout, Uchiyama took part in a public work out with him and his team talking about the bout with Corrales.
The 36 year old champion looked sharp at the work out, and made a point of stating that he was closing in on the 130lbs weight limit for his, with the weight coming off naturally as he worked his way towards the bout. Interestingly he also seemed to suggest that he was close to the best condition of his career, and is expecting to be in the same shape as he was in his last defence.
When it comes to Corrales it seems Uchiyama and his team have been scouting him since the bout was in talks and are aware of his defensive ability, his unusual shoulder roll guard and his quick jab.
Sadly it's not the bout Uchiyama or the Watanabe team had been wanting, with them holding talks to face both Nicholas Walters and Javier Fortuna, though they will be hoping to secure a big bout next, if he can see off the tricky and slippery Corrales.
*The Japanese record is actually held by Momo Koseki however given that Koseki's a female fighter her record is lightly regarded with many viewing Gushiken's record as the more legitimate Japanese record.
