The locally run buses only cost a ¥1 and are regular enough to be relied upon. The town is not that big so going by foot is an option. If you want to go to the Three Visitors Cave, take bus 10 leaving at the main Square (hourly or half hourly). A taxi ride out there is ¥10-20. Taxi fares begin at ¥6 and then increase in small amounts over time and distance. Taxis may or may not use the meter, if you stay in the downtown limits, rides should not exceed ¥10.
