Tokyo reported 20 new cases of novel coronavirus infection Friday, a level lower than the 28 logged on the previous day, but residents still remain concerned that the capital may be seeing a possible resurgence of infections after the state of emergency was lifted late last month.

Friday's figure brings the total COVID-19 infections in the capital to 5,343, the Tokyo Metropolitan Government said. The figure also marks the fifth consecutive day of double-digit increase since Monday.

On Tuesday, Gov. Yuriko Koike issued the so-called Tokyo Alert, which serves as a call for caution but would not move back the phases for reopening businesses that have already been implemented, according to Koike.

Tuesday's 34 cases were the highest since Japan fully lifted its state of emergency on May 25.

Yasutoshi Nishimura, the Cabinet minister in charge of issues related with the pandemic, said Thursday he has a "sense of crisis" about the situation in Tokyo, adding that he will discuss possible steps with Koike over the weekend.
