Since Iriomote is a large island, we need some mobility for sightseeing of the island.  Although a rent-a-car is the most convenient, actually it is not inexpensive.  So, we can use a rental bicycle to go to some near sightseeing spots such as Star Sand Beach, Tsukigahama Beach and Pinaisara (I hear that a man got to Yubu Island from Kanpira-so and back by bicycle).  For solitary sightseeing, a rental motorcycle is more economy than the rent-a-car.  A bus on a regular route is not very useful because it runs a few times a day, but it may be available to get to some particular places such as Iriomote Hot Spring and Yubu Island.  Rich people can make sightseeing by taxi.  
     All of the services shown here are available at Kanpira-so.  See  here for general information in the eastern part of Iriomote, and see here for that in the western part of Iriomote.
