To enter Japan in 2026, travelers generally require a valid passport and, depending on their nationality, either a visa-exempt status or a pre-approved visa (including the eVisa for eligible short-term tourists). For most visitors, the most efficient way to clear immigration is by using the Visit Japan Web service, where you can pre-register your immigration and customs declarations to generate a QR code for faster processing upon arrival. While COVID-era health certificates are no longer required, you must still provide proof of return or onward travel if requested. Additionally, some travelers may be asked to show proof of sufficient funds for their stay, such as recent bank statements or a credit card. Always ensure your passport has at least six months of validity remaining from your date of entry to avoid any potential boarding issues with airlines.
