Once you arrive at Okinawa Airport, notify the rental company and they'll send a car to pick you up. This time, we rented a Honda Fit. It's a compact car, but the trunk can accommodate three 26- to 28-inch tires! The owner and staff speak Mandarin and English, making communication easy. They were friendly and polite, and they even provided reminders about driving in Okinawa. They were always available to answer any questions and ensured the car was returned with a full tank of gas. After returning the car, they drove us back to the airport. I was very satisfied with this road trip! I'll definitely rent a car from this company again when I visit Okinawa!
