An comes from a family with a strong martial arts background. His father worked as a karate coach, and his younger brother An Yeong-Rim competed in karate at the national level before transitioning to amateur MMA fighting.
In December 2021, An announced his retirement from competitive judo. His career has left a lasting impact on the sport. Born in Tokyo after his family moved from Korea for educational reasons, An studied at the University of Tsukuba. He won gold medals at the 2013 All Japan Student Judo Tournament, which led to an offer to represent Japan.
Despite opportunities to represent Japan, An chose to compete for Korea. In 2014, he transferred to Yong In University in Korea and was selected for the Korean national team later that year. His decision reflects his deep connection to his heritage and commitment to representing Korea on the international stage.
Post-retirement, An plans to focus on coaching young judokas in Korea. He aims to share his knowledge and experience with the next generation of athletes. His philosophy of "Always be humble" will undoubtedly guide his approach as a mentor.
An Chang-Rim's journey in judo is marked by significant achievements, challenges, and a deep commitment to his sport and heritage. His legacy will continue through his contributions as a coach and mentor in the world of judo.
