Do we need a visa to visit Okinawa, Japan?

Question:

Answer:

You must have a valid passport and an onward/return ticket for tourist/business "visa free" stays of up to 90 days. Your passports must be valid for the entire time you are staying in Japan. U.S. citizens cannot work on a 90-day "visa free" entry. As a general rule, "visa free" entry status may not be changed to another visa status without departing and then re-entering Japan with the appropriate visa, such as a spouse, work, or study visa.
