The Tokyo metropolitan government reported 920 new coronavirus cases Wednesday, marking the highest daily figure since May, amid a resurgence of infections with less than three weeks to go until the start of the Olympics.
Tokyo's seven-day rolling average of infections per day stood at 631.7, above the 500 mark that indicates Stage 4, the worst level, on the government's four-point scale for the pandemic's severity.
The recent uptick comes as the government is leaning toward maintaining the COVID-19 quasi-state of emergency covering the Tokyo metropolitan area beyond its initially scheduled end on Sunday.
The Japanese capital reported 1,010 new COVID-19 cases on May 13.
The rebound in COVID-19 cases has been fueling public skepticism about staging the Tokyo Olympics, set to begin on July 23, amid concern that the games could be a superspreader event.
Prime Minister Yoshihide Suga is expected to finalize the decision to extend the quasi-state of emergency for Tokyo and three neighboring prefectures on Thursday.
