Tokyo's governor is urging residents to stay home this weekend unless they absolutely must go out. The call comes after officials confirmed more than 40 new cases of the coronavirus on Wednesday ... the largest one-day spike the city has seen so far.

Yuriko Koike told reporters on Wednesday, "We are now at a critical juncture. We want Tokyo residents to realize this and do their work at home as much as possible on weekdays ... though we understand that may not be possible depending on your line of work. We want people to refrain from going out at night. We also want residents to refrain from going out this weekend, unless it is urgent."
