The heat of the Rio Olympics is such that it can be felt even in Japan.

On Tuesday, Ueno Park in Taito Ward, Tokyo, drew families and students eager to watch the final of the men's 200-meter freestyle swimming on a giant monitor prepared by the organizing committee for the 2020 Olympics and Paralympics.

"I became interested in the Olympics after watching Japan winning the gold medal in gymnastics," said 17-year-old high school student Atsushi Seino.
