Synchronized swimming has been an event in every Summer Olympics since the 1984 Summer Olympics in Los Angeles, and it was also an Olympic event after World War II. The early powers were the United States, Canada, and Japan, and medals were won by all three. However, after the 2000 Olympics, Russia emerged as a new power, winning all gold medals in six consecutive Olympic Games in 2020. Among the three countries in the early days, only Japan has maintained a stable medal-winning strength. Currently, it has only failed to win a medal in 2012, 2020 and 2024. It is the country with the most medals.
