The U.S. State Department on Tuesday eased its advisory that had warned Americans not to travel to Japan, just two weeks after raising the alert to the highest level of four as the country struggles to contain the coronavirus pandemic ahead of the Tokyo Olympics.

Reflecting the latest assessment by the Centers for Disease Control and Prevention, the department has returned Japan to level three, indicating a destination to which Americans should "reconsider travel."

On Monday, the CDC updated its criteria used to determine its travel health notice levels "to better differentiate countries with severe outbreak situations from countries with sustained, but controlled, COVID-19 spread."
