Nikkei wrote that Japan is planning to begin gradually easing in October its overseas travel alerts currently in place for 159 countries and regions, starting with 10 countries and regions that have low numbers of new COVID-19 cases. Japan has issued travel advisories for infectious diseases in four categories. The warnings are not legally binding, however, and receiving countries have the power to accept or reject the entry of travelers from Japan. As of Monday, Japan had placed 159 countries and regions, including the United States and China, at level 3, which urges Japanese nationals to avoid traveling there. Beginning next month, Japan will lower its warning level to 2 for countries with low numbers of cases in the last two weeks, such as Australia, New Zealand, Vietnam, and Brunei. Level 2 advises Japanese nationals to avoid nonessential travel. People who travel to these countries will still be required to quarantine for two weeks upon their return to Japan.
