Prime Minister Shinzo Abe on Monday evening justified extending the state of emergency nationwide until May 31 but vowed to gradually relax some restrictions to resuscitate the economy.

Abe, holding a news conference, showed a dose of cautious optimism that the number of coronavirus patients is on a downward slope as he claimed the emergency declaration has been effective and thanked the public for cooperating.

At the same time, he said the situation remains grim, pointing out that the number of patients in critical condition requiring a ventilator has tripled in the last month and nearly 10,000 patients are still undergoing treatment, including hospitalization.
