Good news again about the convenient shuttle bus service between Kinosaki Onsen and Genbudo Caves!! Why not take this Zentan shuttle bus and explore around the caves?? You might have an exciting encounter with wild oriental white storks on the road, too!
Additionally only for foreign tourists, "Zentan Green Pass" (One Day Pass) is sold at Sozoro Tourist Information Counter just in front of JR Kinosaki Onsen station. It costs 500 yen per adult. http://www.zentanbus.co.jp/wp-content/uploads/2013/12/ura.pdf
For more information, please feel free to contact the staff at Sozoro. http://global.kinosaki-info.com/access/
