Satoshi Shimizu is a Japanese professional boxer who has held the OPBF (Oriental and Pacific Boxing Federation) featherweight title since 2017. He is also an Olympic bronze medalist in the men’s bantamweight division at the 2012 London Games. He is known for his nickname “Diamond Left” and his southpaw stance.

Shimizu was born on March 13, 1986 in Sōja, Okayama. He started boxing at a gym in Kurashiki, Okayama in the third grade of junior high school. He graduated from Komazawa University and joined a children’s clothing maker, Miki House, as an employee. He was also a second lieutenant in the Japan Ground Self-Defense Force in 2012.

Shimizu had a successful amateur boxing career, winning several national and international titles. He competed at the 2008 Beijing Olympics at featherweight but lost his first bout to Yakup Kılıç of Turkey. He then moved down to bantamweight for the 2012 London Olympics, where he won the bronze medal after a controversial quarter-final bout against Magomed Abdulhamidov of Azerbaijan. Shimizu knocked down his opponent six times in the third round, but the referee did not stop the fight or give any warnings. Shimizu was initially declared the loser by points, but the decision was overturned after an appeal by the Japanese coach.

Shimizu also won the bronze medal at the 2009 Asian Championships in Zhuhai, China, and participated in the 2010 Asian Games in Guangzhou, China, but lost in the quarter-finals. He was Japan’s first men’s boxing medalist since 1968.

Shimizu turned professional at the age of 30, on September 4, 2016. He made his debut against In Kyoo Lee of South Korea and won by knockout in the fourth round. He then won his next nine fights by knockout or technical knockout, including against Carlo Demecillo of the Philippines, Takuya Yamamoto of Japan, Sa Myung Noh of South Korea, Eduardo Mancito of the Philippines, Kyung Min Kwon of South Korea, Shingo Kawamura of Japan, Takuya Uehara of Japan and Joe Noynay of the Philippines.

Shimizu’s first professional loss came on July 12, 2019, when he faced Landy Cris Leon of Mexico for the WBO Asia Pacific super featherweight title at EDION Arena Osaka. Shimizu was stopped by technical knockout in the sixth round after suffering a cut over his right eye.

Shimizu bounced back from his defeat and won his next two fights by unanimous decision against Musashi Mori of Japan and by retirement against Kyohei Tonomoto of Japan. He defended his OPBF featherweight title in both bouts.

Shimizu is currently ranked #20 by BoxRec and #2 by WBO in the featherweight division. He is scheduled to face Robeisy Ramirez of Cuba for the WBO world featherweight title on July 25, 2023 at Ariake Arena in Tokyo.
