No, as of March 2026, you do not need to show proof of vaccination or a negative COVID-19 test to enter Japan. The Japanese government officially dropped all pandemic-related entry requirements in 2023, returning the country to pre-pandemic immigration rules. Travelers from "visa-exempt" countries (such as the US, UK, Canada, and Australia) can enter Japan for up to 90 days for tourism with just a valid passport. While there are no health-related mandates, visitors are still highly encouraged to use the Visit Japan Web portal before they fly. This official app allows you to pre-fill your immigration and customs declarations, generating QR codes that significantly speed up your processing time upon arrival at Narita, Haneda, or Kansai airports. Although masking is no longer required by law, you will still see many locals wearing masks in crowded trains or shops as a matter of social etiquette and personal health. Travel insurance that covers medical emergencies is not a legal requirement for entry, but it is strongly recommended by the Japanese National Tourism Organization for all international visitors.
