A delta-driven surge in COVID-19 cases is coming to a faster-than-expected end in Japan, but experts warn another wave of infections may be just around the corner.

The country¡¯s fifth wave was the most explosive yet and wreaked havoc on the nation¡¯s health care system.

But the surge has subsided significantly since its mid-August peak. Health ministry data shows there were 2,661 new cases confirmed nationwide on Saturday, a dramatic drop from the middle of last month when the daily tally routinely topped 20,000 and peaked over 25,000.
