Tokyo has recorded its fourth record number of daily Covid-19 infections in the last 24 hours, breaking above 10,000, while Japan's exceeded 50,000 for the first time as the Omicron variant continues to spread rapidly, Reuters reports.

The capital had 11,227 new coronavirus cases, the local government said a day after it reinstated curbs on mobility and business activity through February 13. Tokyo's case count, exceeding the previous day's 9,699, was more than double the 4,561 logged a week earlier.

Infections nationwide totalled at least 50,200 as nearly 30 of Japan's 47 prefectures set records, broadcaster FNN reported.
