Kurago Cave

Kurago Cave cuts roughly 600 meters through limestone on Kojima Island, opening at the far end onto a coastal reef. Rainwater filtering through the plateau above feeds underground springs, and the cave mouth spring once served as a fresh water source for nearby villagers, who drew the year's first water here at New Year. About 100 meters in, Kurago Falls drops 10 meters into a subterranean pool. Beyond that, passages become more demanding, with thigh-deep water and low ceilings in places. The cave is intended for experienced, self-sufficient cavers. There is no lighting inside, and some sections are submerged, so carry your own light source and a backup.
