Tokyo confirmed 12 new COVID-19 cases on June 9, the ninth straight day the tally has reached double digits, health officials and other sources said.

The new cases brought the overall total to 5,408 infections in the capital.

The Tokyo metropolitan government issued a “Tokyo alert” on June 2 to warn residents to remain vigilant about a possible second wave of the contagion, about a week after the state of emergency was lifted for the metropolis.
