TOKYO — Tokyo has reported 678 new cases of the coronavirus, a high for the Japanese capital, as Japan now struggles with another surge in the virus.

The Tokyo Metropolitan Government said Wednesday that the new cases bring the prefectural total to 48,668.

Infections have been on the rise nationwide. Japan had more than 2,410 cases Tuesday for a national total of 184,042, including 2,688 deaths.

Prime Minister Yoshihide Suga, apparently reluctant to further damage businesses already hit by the pandemic, has been slow to take steps. Last Friday, after repeated calls from experts, Suga finally announced plans to suspend the government’s travel promotion campaign nationwide from Dec. 28 to Jan. 11 following a series of media surveys showing a sharp decline in his approval ratings.
