Tokyo is on edge after Gov. Yuriko Koike called on residents Wednesday night to stay inside, work remotely and avoid nonessential outings this weekend to avoid an explosive rise in the number of novel coronavirus infections.

The Tokyo Metropolitan Government will reportedly announce 47 new cases of infection Thursday, marking four record-breaking days in a row since 16 additional cases were reported Monday, 17 on Tuesday and 41 on Wednesday.

“It’s crucial that we encourage awareness among the people around us, and figure out what we can do together to overcome these circumstances,” Koike said during a news conference Wednesday night.
