Daiki Hashimoto

Hashimoto competed at the World Championships in Stuttgart, Germany, where his team placed third all around.[4] On the pommel horse, he finished in 9th place, and on the horizontal bar, he finished in 4th place.

Hashimoto's breakthrough arrived when he became the champion of All Japan AA Championships. His score of 88.532 was the highest of 2021 until being surpassed by Zhang Boheng's 88.565 result at the Chinese Olympic Trials. One month later, Hashimoto participated in NHK Trophy, and despite only achieving the second highest score of the night, he still won the title because the tournament also used the scores of All Japan AA Championships for the final results. In June, Hashimoto achieved another victory at the All Japan Event Championships. With such impressive performances, he was later selected in Japan men's national gymnastics team competing at the Olympics.

At the Olympics, Hashimoto competed in team event with Kazuma Kaya, Takeru Kitazono, Wataru Tanigawa & won the silver with only 0.103 points behind the ROC team..[5][6][1] He also won two gold medals in all-around and horizontal bar,[1] making him the most successful male gymnast in Tokyo with three medals — two golds and one silver. Being just 10 days before turning 20, Hashimoto also became Japan's second youngest and one of only two teenage male gymnasts in history to accomplish that feat after Kenzō Shirai, who won team gold six days younger in 2016. This would also include by default Hashimoto becoming the youngest Japanese gymnast to win Olympic gold on the all-around and horizontal bar events. In the men's individual floor exercise and pommel horse event finals, Hashimoto would place eleventh and ninth.

At the 2021 World Championships in Kitakyushu, Japan, Hashimoto was the top qualifier on the men's individual all-around and horizontal bar, but only earned two silver medals on those events. He also placed fourth in the parallel bars, and withdrew from floor and pommel horse, despite qualified for the finals.
