A FEW TIPS
1. You raise your hand when you want to get on.
2. Though there are four different bus companies running, they all use the same numbers for the same routs, so you just have to pay attention to the #s. When you get on a bus in Naha city, the buses that have # between 1 and 19 (except for 15) only run inner City. Buses that have # 15 and 20 or bgger number run outside of the city.
3.If you wanna site see inner Naha city like Kokusai St. and Shuri castle, and beaches, you can purchase a one-day pass. It costs about as much as you pay for one time.
