Fans from abroad were banned several months ago. Organizers set a limit of 50% of capacity up to a maximum of 10,000 fans for all Olympic venues. The decision contradicts the country’s top medical adviser who recommended last week that the safest way to hold the Olympics during the pandemic would be without fans. Japan’s prime minister, who has favored allowing fans, said before the official announcement that local fans would be barred if conditions change. The Tokyo Games are set to open on July 23.— CNBC’s Leslie Josephs and The Associated Press contributed to this report. Follow all the market action like a pro on CNBC Pro.
