The U.S State Department has now advised against travel to Japan as it grapples with a new wave of coronavirus cases.
The news on Tuesday comes just months before the Tokyo Olympics are set to be held and Japan was quick to respond.
Chief cabinet secretary Katsunobu Kato said hours later the advisory won't affect U.S support for actually holding the Games.
"We believe that there is no change in the U.S. position to support the Japanese government's determination to realize the hosting of the Tokyo Olympics and Paralympics."
The U.S. "Do Not Travel" advisory and guidance for Japan did not mention the Olympics specifically but warned against visiting the country at this time.
The U.S Olympic and Paralympics Committee said in a statement to Reuters
that it was aware of the updated travel advisory but was quote "confident" that the current mitigation practices in place for athletes and staff, including testing before arrival and during the Games time, will allow for safe participation.
The Games are scheduled to kick off on July 23 even under Japan's state of emergency.
