Hiroyuki Yoshino (12-3-1, 9) Vs Masumi Yamaguchi (4-3, 3)
On the world stage Japanese fighters are better known for what they do at the lower weights. Domestically however we often find some of the most explosive coming in the more middling range. One example of that is this short Japanese Welterweight title bout between Hiroyuki Yoshino and Masumi Yamaguchi, that saw every punch being thrown with bad intention. This is short but sweet.
