yes. you will need a passport to visit Okinawa, Japan if you are traveling from the United states. if you plan to stay upwards of 90 days in Okinawa or Japan in general, you will need to get a travel Visa. if you plan to work while you are there you need a visa for that as well ( im not sure if work visa's can count as travel visa's as well).
