Memorial at the 730 Crossing Ishigaki, Okinawa, Japan,
In 1972, Okinawa rejoined Japan. Six years later, on 30th July 1978 traffic rules reverted, so that once again cars drove on the left. A small memorial beside the 730 Crossing on Ishigaki island, serves as a reminder.

I heard that cars were continuously crashing into each other all along Highway 58 following the conversion. I guess much hasn’t changed… 🙂
