Senbutsu Limestone Cave

The Senbutsu Cave, which stretches across the karst plateau of Hiraodai, is one of the largest caves in Japan and is designated as a national natural monument. Located at an elevation of 300m above sea level, the interior of the cave, which meanders northeastward, can be viewed up to about 900m where there is a lighting system. The path through the cave is like an art gallery of nature! The cave is a narrow, high-ceilinged canyon with a maximum width of about 10 meters and a ceiling height of about 15 meters, making it an impressive sight to behold.
At the entrance, about 30 stalactites of various sizes hang down, creating a mysterious atmosphere that seems to invite visitors into another world. As you proceed through the cave, underground water appears after 480 meters. The water can reach adult knee height in the deepest points. It is a good idea to borrow sandals at the entrance. Enjoy a thrilling 40-minute round-trip adventure, splashing your way through the water.
The temperature inside is about 16 degrees Celsius year-round, making it popular as a “natural cooler." In summer, it is crowded with tourists seeking to cool off.
