Corrected entry: When Daniel and Mr. Miyagi are picked up at the airport in the car, they are driving and the steering wheel is on the left of the car. In Japan, steering wheels are on the right. And if you look carefully, all of the other cars are also driving on the right hand side of the road instead of the left side of the road.

Correction: They aren't in mainland Japan, they are in Okinawa. Okinawa was under the control of the American military until 1978 and during that time, traffic flowed on the right not the left. While it changed in 1978, there were still many cars that had left-side drivers.
