Tokyo reported 317 new cases of the novel coronavirus Wednesday — the first time the capital has recorded more than 300 in a single day since late August — amid an ongoing surge in new infections throughout the country.

Individuals in their 20s, 30s and 40s accounted for 187 — more than half — of the 317 infections announced by the Tokyo Metropolitan Government. The capital conducted just 1,010 polymerase chain reaction tests Sunday. The results of the tests on Sundays, which often take three days to be received, collected and reported, are demonstrably lower than on weekdays, when the capital routinely conducts over 4,000 tests.

As of Wednesday afternoon, the capital has reported more than 33,000 infections. 38 individuals are currently hospitalized with serious symptoms, according to the metropolitan government.
