The bout is for a title given up at the turn of the year by Ryosuke Iwasa, who is now set to get a shot at the IBF interim Bantamweight title, and although it's not between the top fighters in the Orient it does promise a lot of action with styles that should gel to provide a lot of exciting action and exchanges.
Of the two men it's Kawaguchi with the most to lose considering the 28 year old is just a year removed from a loss against Kentaro Masuda for the Japanese Bantamweight title. Although the more experienced fighter Kawaguchi has come up short in his most notable bouts to date including the Masuda bout and a contest to Yasutaka Ishimoto. Considering he has been a professional for more than a decade however he will likely know that it's time he showed what he was really capable of.
Aged 24 the hard hitting Yamamoto turned professional in 2008 and he's now unbeaten in more than 4 years, following a run of 1-3. He enters this bout on the back of 9 wins with the last 6 coming inside the first 3 rounds of a fight. This is however his first title bout and sees him facing his best foe since that winning run began back in 2012.
