With blunt warnings, flip-charts and daily online briefings, Tokyo Governor Yuriko Koike has been delivering a tough message to the Japanese capital’s residents and shops: stay home and shut down to avert an explosive outbreak of the coronavirus. Koike, 67, was once floated as a future premier. Japan had 7,411 cases of infection and 138 deaths from the virus as of Monday, public broadcaster NHK said, with more than 2,000 cases in Tokyo, a sharp rise from late March.
