Swimming At The 1952 Summer Olympics – Men's 1500 Metre Freestyle

This swimming event used freestyle swimming, which means that the method of the stroke is not regulated (unlike backstroke, breaststroke, and butterfly events). Nearly all swimmers use the front crawl or a variant of that stroke. Because an Olympic size swimming pool is 50 metres long, this race consists of 30 lengths of the pool.

Even though the top three swimmers were from different countries, all of them were of Japanese origin. Ford Konno was Japanese American and Tetsuo Okamoto was Japanese Brazilian.
