TOKYO (Reuters) - Tokyo has confirmed more than 50 new coronavirus cases, which is a record daily increase, national broadcaster NHK reported on Saturday.

Tokyo Governor Yuriko Koike has requested that tens of millions of people in the capital and surrounding regions should avoid non-essential, non-urgent outings until April 12, following a surge in coronavirus infections this week that she said put Tokyo on the brink of an emergency.
