On July 6, 1912, Mishima served as a standard bearer for the opening ceremonies of the 1912 Olympics. The same afternoon, although he tied his personal record, he was eliminated in the first round of the 100 meters competition by more than one second, coming in last place. He came in fifth (and last) place in the first heat of the 200 meters competition. In the 400 meters competition he advanced to the semi-finals in second place, but since there was only one other runner, this was also last place. He defaulted the final race due to pain in his right leg. He left Stockholm before the closing ceremonies to visit Berlin, where he examined the grounds for the 1916 Summer Olympics, and to purchase sports equipment then not available in Japan, returning home only on February 7, 1913. However, the 1916 Berlin Olympics were cancelled due to World War I, and Mishima was unable to qualify for the 1920 Summer Olympics in Antwerp, Belgium.
