Whether it is sumo, domestic basketball or baseball games, Japanese fans have been filling arenas in recent days, leaving Olympic athletes wondering why they will be competing in front of empty stands at the Tokyo Games.

Japanese organizers have decided to ban spectators from venues of the Olympics, which start this week, in a bid to stem an increase of COVID-19 infections, with the capital in a state of emergency until Aug. 22.

Foreign visitors were banned earlier from attending the delayed Tokyo 2020 Games.
