Prime Minister Yoshihide Suga on Thursday declared a second, albeit less comprehensive, state of emergency in Tokyo, Kanagawa, Saitama and Chiba prefectures to contain the fast-spreading coronavirus, which has stretched parts of the nation’s health care system to breaking point.

“I’m highly alarmed by the severe situation nationwide recently ... as the number of patients has been extremely high," Suga said at a government task force meeting, adding the Go To Travel domestic tourism program will be suspended while the state of emergency is in effect.

The restrictions will enter into force Friday and remain in place until at least Feb. 7. They will not be lifted until the affected prefectures see a significant reduction in benchmarks such as hospital occupancy rates and positivity rates.
