Answer the following Q with stream of consciousness. Passage: This is a list of host cities of the Olympic Games, both summer and winter, since the modern Olympics began in 1896. Since then, summer games have usually -- but not always -- celebrated a four-year period known as an Olympiad. There have been 28 Summer Olympic Games held in 24 cities, and 23 Winter Olympic Games held in 20 cities. In addition, three summer and two winter editions of the Games were scheduled to take place but later cancelled due to war: Berlin (summer) in 1916; Tokyo / Helsinki (summer) and Sapporo / Garmisch-Partenkirchen (winter) in 1940; and London (summer) and Cortina d'Ampezzo, Italy (winter) in 1944. The 1906 Summer Olympics were officially sanctioned and held in Athens. However, in 1949, the International Olympic Committee (IOC), decided to unrecognize the 1906 Games. Four cities have been chosen by the IOC to host upcoming Olympic Games: Tokyo for the 2020 Summer Olympics, Beijing for the 2022 Winter Olympics, Paris for the 2024 Summer Olympics, and Los Angeles for the 2028 Summer Olympics.

Question: Based on this passage, where are the upcoming olympics to be held?
The relevant information is: Four cities have been chosen by the IOC to host upcoming Olympic Games: Tokyo for the 2020 Summer Olympics, Beijing for the 2022 Winter Olympics, Paris for the 2024 Summer Olympics, and Los Angeles for the 2028 Summer Olympics.
