The Tokyo Metropolitan Government confirmed 161 coronavirus infections Monday, marking the lowest figure since July 27, but the start of the new work week following the Bon summer holidays has rekindled worries over a rise in fresh infections across the country in the coming days.

The figure, which compared with 260 cases a day earlier, pushed the cumulative tally in the capital to 17,875, with 340 deaths and 25 in serious condition. Monday's results came after 2,780 tests were conducted Friday.

The metropolitan government has raised its alert for the pandemic to the highest of four levels, meaning infections are spreading. Karaoke venues and drinking establishments that serve alcohol are also being asked to close by 10 p.m. until the end of this month.
