Located between Hida Takayama and Okuhida Onsengo, this is one of Japan’s leading limestone caves, extending for about 800 meters (about 2,625 feet). It is also Japan’s highest-altitude show cave. Inside the cave, formed by nature over many years from a coral reef dating back 250 million years, visitors can see delicate white stalactites. Another notable feature is that it has more rare cave formations known as helictites than any other limestone cave in Japan.
The cave is illuminated, creating an otherworldly atmosphere. It was designated a Lover’s Sanctuary on March 1, 2017. Visitors can display “Keys of Promise” and “Ema Votive Plaques of Promise.”
Nearby is Ryomen Sukuna Cave, said to have been home to Ryomen Sukuna, a character featured in the popular manga “Jujutsu Kaisen.” Visitors can also stop there to pay their respects.
Wine, sake, and shochu stored at low temperatures in the cave are popular souvenirs. The adjoining Ohashi Collection Kan Museum displays approximately 1,000 works of art, decorative objects, and other items from around the world collected by the late Sotokichi Ohashi, who discovered the Hida Great Limestone Cave.
