From what we've been told Tanaka will spend 3 days with Nietes, who recently defended his world title against Gilberto Parra, in the hope of honing his skills against of the best little men in the sport. From what we under-stand the idea isn't to get Nietes to mimic Yedras but instead to give Tanaka high quality rounds so that he can improve his own abilities and work on his flaws.
The intention for Kosei seems to be clear. Not only does he want to improve but he wants to make a statement when he sets foot in the ring with Yedras. He's already said he will be hunting a KO in the bout, in fact some reports suggest he is aiming for a 6th round KO, and of course he's also hunting a slice of history by becoming the quickest ever Japanese world champion.
Whilst the sparring is certainly going to be useful for Tanaka it's also going to be good for Nietes who now has a world title defense against Francisco Rodriguez Jr (17-2-1, 11) in summer. Again it's unlikely Tanaka will be replicating Rodriguez Jr but it's high quality sparring for Nietes who will be hoping to get in all the top quality rounds he can ahead of what promises to be a very tough fight for the Filipino.
