Are all the competitions of the Tokyo Olympic Games held in Tokyo? Are some competitions held in other cities?

Is this right? Not all the competitions of the Agricultural Olympics are held in Tokyo. In this Tokyo Olympic Games, some competitions were held in other cities outside Tokyo. For example, the 20 km race was held in Sapporo, Hokkaido. Mainly considering that the food in Tokyo is spicy and the weather conditions in Sapporo are better. But in fact, it was quite hot on the day of the game, because the temperature was very high, and then it was even wetter, and the humidity and temperature were very high.
