TOKYO —Tokyo reported 5,042 new coronavirus cases on Thursday, its most since the pandemic began as infections surge in the Japanese capital hosting the Olympics. Tokyo has been under a state of emergency since mid-July, and four other areas of the country have since been added. But the measures, basically shorter opening hours and a ban on alcohol for restaurants and bars, are increasingly ignored by the public, which has become tired of restrictions. “We need to tackle the situation now that we have a stronger sense of urgency,” Prime Minister Yosihide Suga told reporters, referring to Tokyo exceeding 5,000 new daily cases for the first time.
