Japan is considering extending its coronavirus quasi-state of emergency in Tokyo and three adjacent prefectures, government sources said Wednesday as a rebound in COVID-19 cases has raised the possibility of the capital hosting the Olympics without spectators.

Prime Minister Yoshihide Suga's government will make a decision next week on a possible extension beyond the emergency's expiration on July 11, just before the Summer Games open on July 23, the sources said. Some in the government speculate Suga may declare another state of emergency in the Tokyo area.

Earlier Wednesday, the Tokyo Metropolitan Government reported 714 new daily coronavirus cases, reflecting a sharp rebound in the 10 days since the capital exited a state of emergency and shifted to quasi-emergency measures.
