The Tokyo Metropolitan Government re-sounded the alarm for the capital after 34 new coronavirus infections were confirmed in the city Tuesday, a day after it eased business closure requests for sports gyms and department stores.

“The purpose of this alert is to make residents aware of our precarious situation and urge them to be cautious,” Gov. Yuriko Koike said during a meeting of the city’s coronavirus task force on Tuesday night.

Officials say the brief rise in new cases can largely be attributed to nosocomial infections as well as people partaking in nightlife activities in the Shinjuku area.
