The Tokyo Metropolitan Government reported 189 new COVID-19 infections on Friday, resetting the single-day record for a third consecutive day and lifting the capital's total above 1,700.
At the same time, Tokyo revised Thursday's tally of 181 cases downward to 178, overtaking the previous high of 144 set on Wednesday.
The metro government also reported four more deaths on Friday, bringing the total to 40. At least 20 of the deaths are linked to Eiju General Hospital in Taito Ward, now a well-known "hot spot" in the capital.
As in the past few days, Friday's figure featured a growing ratio of younger patients in their 20s and 30s in addition to infections that can't be traced, the metro government said.
Tokyo remains in a state of emergency along with six prefectures.
