Ginryudo Cave

Ginryudo is a 200-meter limestone cave on Kenbuchi Island, formed over centuries by acidic water dissolving the rock. A single passage follows an underground stream, ranging between 2 and 5 meters wide, ending at a subterranean pond. About halfway along the route, a stalactite platform holds a small shrine to the village's guardian deity, still active today and the reason for the rustic torii gate at the cave entrance. The cave sees few visitors now compared to its popular days in the 1960s. There are no installed lights, so bring a headlamp and a backup. The path is frequently wet and slippery in sections.
