To travel to Japan in 2026, you primarily need a valid passport (ideally with at least 6 months' validity), a Customs Declaration, and a Disembarkation Card (both of which can be completed digitally via the Visit Japan Web portal). As of 2026, Japan has fully removed all pandemic-era health entry requirements, meaning you no longer need proof of vaccination or a negative COVID-19 test. However, travelers from certain countries—including many in South Asia and Africa—must still obtain a physical or e-Visa before arrival. For 2026 visitors, having travel insurance with full healthcare coverage is "strongly recommended" because Japanese medical providers often require payment upfront or proof of insurance before treating foreign nationals. Additionally, while the "Japan Rail Pass" remains a popular tool, you should ensure you have an IC Card (like a digital Suica or Pasmo on your phone) for local transit and "konbini" payments. Carrying a small amount of cash is still advisable for rural areas, but 2026 Japan is much more credit-card friendly than in previous decades.
