Shimizu, who claimed an Olympic bronze medal at the London games in 2012, became the first Japanese boxer to claim a medal since Eiji Morioka in 1968. Despite his achievements of winning a medal he was over-shadowed by Murata, who of course went onto win gold. With the medal around his neck there was plenty of expectation that Shimizu would follow Murata and would turn professional himself, instead however Shimizu remained in the unpaid ranks.
Whilst Shimizu's bronze medal was his major achievement in London, losing in the semi-final to Britain's Luke Campbell, he is best known for his controversial bout with Magomed Abdulhamidov of Azerbaijan. That bout was originally ruled a victory for Abdulhamidov before AIBA over-ruled the decision due to some seriously suspect officiating from the referee.
Aged 27 Shimizu has so far claimed Olympic and Asian Championship medals as well as numerous national titles and a host of major national awards. It seems however that he won't be happy until he wins and Olympic gold medal.
The Rio games will be Shimzu's 3rd after having also participated in the Beijing 2008 games. We wish him the best in following in Murata's footsteps then hope to see him turning professional
