Ootaki Limestone Cave is a sprawling subterranean network in Gujo, Gifu, housing one of the largest underground waterfalls in Japan. Visitors reach the cave entrance via a short wooden cable car ride that ascends the mountainside. The interior features complex stalactite formations and narrow passages carved by ancient water flow. The 30-meter high waterfall, known as Ootaki, serves as the cave's centerpiece and primary destination. The cave maintains a constant cool temperature throughout the year, regardless of external weather conditions. It is part of a larger geological area characterized by karst terrain. The site includes facilities for fishing and dining on local specialties like river fish. Access to the furthest reaches of the cavern involves climbing internal staircases.
