In 2010, Shiraki married, and following the wedding he legally changed his name from Daisuke Sugie to Daisuke Shiraki. Two years later, in 2012, he made a significant institutional move by joining Carpe Diem, one of Japan's most prominent and successful BJJ organizations. The affiliation deepened his connection to the highest level of Japanese jiu-jitsu and provided a platform for the next phase of his career.
Opening CARPE DIEM HOPE in Gifu
Shiraki channeled that momentum into building the sport locally, opening his own branch — CARPE DIEM HOPE — in Gifu city. The academy expanded the Carpe Diem network into a region where his competitive reputation could inspire a new generation of practitioners, becoming a symbol of his commitment to developing BJJ beyond Japan's major metropolitan centers.
Sustained Excellence in Competition
Far from stepping back after establishing his academy, Shiraki produced some of his finest results well into his thirties. In 2016 and 2017, he captured IBJJF Japanese National Championship gold, affirming his standing as one of Japan's premier domestic competitors. During this same period, he earned 3rd place finishes at the IBJJF World Masters Championship in both 2016 and 2017 in the Master 2 division, demonstrating that his technical and competitive edge remained sharp at the elite level. His nickname 'Amazon' — earned through years of fierce competition — reflected the relentless intensity he brought to every match.
