UPDATE: As of October 10, 2022, Japan lifts visa requirements and eases entry restrictions on foreign nationals. Visas are no longer required to enter Japan for short-term stays within 90 days. ERFS (Entrants, Returnees Follow-up System) will also no longer be required. Visa exemptions for short-term stays apply only if you are a citizen of an eligible country (including the U.S., Canada, and Mexico).
