In no result was the domination of the Japanese men felt more than in the 100 metres backstroke. Amsterdam finalist Toshio Irie and newcomer Masaji Kiyokawa eased into the final by winning their races, and were joined by compatriot Kentaro Kawatsu. The finishing order of the final was Kiyokawa-Irie-Kawatsu, the first time Japan had made a clean sweep of the medals in any Olympic event. The main rival to the Japanese trio should have been Germany’s Ernst Küppers but he committed a false start and, seemingly unnerved by this, he finished in fifth.
Masaji Kiyokawa spent twenty years as a member of the IOC and served as a vice-president of the organization.
