The youngster, headlining a card that also featured a Japanese Featherweight title bout, took on sturdy foe Noboru Osato (7-5-4, 1) [大里 登], who had never been stopped prior to facing Mizuno.
Despite Osato's reputation for being tough the 21 year old Mizuno fought like a man intent on getting the stoppage. Sadly that came at a cost early on, with Osato using his feet and jab to make Mizuno look silly at times. The good start for Osato seemed to suggest that he had the perfect game plan, sadly though it didn't take too long for Mizuno's heavy hands to connect, and in round 5 Osato began to clearly feel the power of Mizuno.
The power of the youngster became too much in round 6, when he dropped Osato with the referee stopping the bout whilst Osato was still down.
Next for Mizuno is an August 23rd match up with Ryota Ishida (7-1, 5) [石田凌太] for the Japanese Youth Bantamweight crown in what looks like a mouth watering match up.
