The 七ツ釜鍾乳洞 (Nanatsugama shōnyūdō) or Shimizu Cave is formed inside a 30Ma old limestone. The small karst area has so far 35 known caves.
The cave also offers cave trekking tours for groups after appointment.
The cave visit is completed by a small museum which shows rocks and fossils from the Paleozoic to Cenozoic. Most of the exhibits are fossils from the local limestone or speleothems from the cave.
