I hear things are stricter in other countries, so I am just capturing this as a datapoint; I got this in an email from U.S. Embassy Tokyo
Japan’s Enhanced Screening and Quarantine Measures for Travelers from the United States: The Government of Japan has implemented enhanced screening and quarantine measures to reduce the spread of COVID-19. Effective March 26, all travelers arriving from the United States, including Japanese citizens, will be required to self-quarantine for a period of 14 days at a designated facility, and to avoid using any public transportation, including taxis, trains, and buses, until after the 14-day period. Transiting on a domestic flight within Japan is also considered public transportation, so you will not be allowed to fly to your onward destination in Japan until completing the 14-day self-quarantine. The self-quarantine location may be your residence if you live in Japan or a hotel, but the Japanese government reserves the right to “designate” the location of your self-quarantine. Travelers should be prepared for travel restrictions to be put into effect with little or no advance notice.
