How many days can I stay in Japan at most?

The average tourist visa stays for less than 15 days. There are also three-year multiple visas, each of which can stay for up to 9 days. However, when you enter Japan for the first time on a multiple-entry visa, you must include Okinawa in your itinerary and stay in Okinawa for more than one night. In the future, you can re-enter Japan with this visa without restrictions.
