The session saw the "God of Left" working on a heavy bag and he looked sharp and ready to go more than a week ahead of his bout.
Whilst the public work out was the key part of the day there was some time for questions and Yamanaka once again promised a KO as he further indicated that wanted to tie the Japanese record of Yoko Gushiken for 6 successive world title defenses by KO.
From what we understand Yamanaka was also using gloves made in a way to add extra sting to his punches, similar in a way to how Cleto Reyes gloves do something similar.
Other comments from the session also indicated that Yamanaka intends to try and unify titles though he did admit that he hasn't been paying huge attention to other fighters in the division. He seemed to suggest that his next fight was focus and not those of others in the division, such as Tomoki Kameda, the current WBO champion who will be defending his title on November 1st in Chicago.
