Tokyo reported 317 new COVID-19 cases on Nov. 11, breaking the 300-level for the first time in almost three months, while Osaka Prefecture confirmed a record daily high of 256 new infections.

The infection tallies in the two urban centers have been steadily increasing as winter approaches.

Osaka Governor Hirofumi Yoshimura announced Nov. 11 count, which was one more than the previous high of 255 reported on Aug. 7. 

In Tokyo, the daily tally hit 293 on Nov. 10 before surging to 317 the following day, according to metropolitan government officials.

The last time the number exceeded 300 in the capital was on Aug. 20, when 339 new cases were reported.

Of the 317 cases, 68 patients are in their 30s, followed by 61 in their 20s, 58 in their 40s and 43 in their 50s. Forty people aged 65 or older also tested positive.

The Tokyo metropolitan government said the number of serious cases requiring ventilators or extracorporeal membrane oxygenation, also known as an ECMO lung bypass machine, increased by five from the previous day to 38 on Nov. 11.
