If you find yourself without a car on Okinawa, you may find the following link to the Okinawan bus lines helpful. Our reader, Erika, submitted the following:

When I was on okinawa last month this website would have been useful for me. Even though I read Japanese, the times on the bus stops arent 100% accurate. This website would help keep you on time and from waiting too long. It shows you the buses locations in real time and where they will be at specified times, and there’s a mobile phone edition available via qrc codes on the website as well.
