Rokan Cave

Rokan Cave is a limestone cave in Sumita with an extensive underground passage system. Visitors can walk through illuminated sections that reveal natural chambers, rock formations, and the scale of the cave's interior architecture.

The cave served as shelter for local people in ancient times and later became connected to regional gold mining operations. This dual role as refuge and mining site shaped its importance in the region's history.

Local guides lead educational tours through the cave, sharing geological knowledge and explaining the natural processes that shaped the underground formations.

The cave entrance is easy to reach and the approach path is straightforward. Inside, illuminated walkways are designed for visitors of various abilities, though sturdy footwear is advisable for the uneven ground.

Deep within the cave system lies Ten no Iwado no Taki, an underground waterfall that plunges dramatically into a natural pool. This hidden cascade is one of the most striking sights inside the cave and often escapes visitors' notice.
