From July 23, until August 8, the 2020 Summer Olympics will take place. Japan will host the Summer Olympics for the second time, 56 years after it originally won the distinction of staging the Games in 1964. That was the first time the Summer Olympic Games were held in Asia.

The International Olympic Committee picked Tokyo in September 2013 to host the 2020 Olympic Games. Istanbul and Madrid were other prospective cities. "United by Emotion," the official motto for Tokyo 2020, reflects a worldwide demand for diversity and acceptance.

In Tokyo 2020, 33 sports will be introduced and around the city and 22 events for paralympic sports are to be staged, including the Heritage Zone and the Tokyo Bay Zone in two major sports facilities. The 68, 000-seater New National Stadium, the primary stadium of the 1964 Tokyo Olympic Games, will be used for the opening and closing ceremonies.

Which country has won the most Olympic medals?

The United States have indisputably won the most gold medals and the most medals overall, almost double the second-placed Russian in all its forms. Russian Athletes have so far appeared at the Olympic Games for five different teams, as the Soviet Union, Russia, Unified Team, Russian Empire, and Olympic Athletes from Russia.

The US can boast of winning almost 2,500 medals in 27 Olympic Games combined. Over 1,000 were gold, over 800 silver, and more than 700 bronze. The former Soviet Union, which earned 440 golden and more than 1,100 total medals in 10 Olympic Games between 1952 and 1992, is the second most successful team in the Summer Olympic history. When the Soviet Union, Russia, and the Russian Empire add their total medal carriers, over 1000 medals still remain below the USA's record.

The third most successful Olympic team in the world is that of the United Kingdom, which since 1896 have taken part in all 28 Olympic Games, and received 851 gold medals. China are fourth with 220 gold medals. However, once all medals won by all German athletes who have represented Germany, West Germany, and East Germany are added together, the total is 428 gold medals and over 1,350 overall. Take a look at the complete list, as countries as ordered by the number of gold medals won.
