RYUGADO CAVE

Nationally designated historical site and natural monument

Deep down in their heart
Ryugado Cave is a place where various sculpture shapes are naturally formed one after another throughout the endless time.

It has been developing from the past, until now and will continue on.

Wander around in this limitless world with your heart open.
On this journey, you will be asking yourself "What is Time", "What is the World", "What is Life", "What is self" which continues on forever, without end.
"The Exploring"
We invite you to a journey where you can discover something that is precious to you.
Designated a national natural monument and historic site, Ryugado Cave was formed over 175 million years ago. The cave is approx. 4km in length and about 1km of this is open to the public. Among the mysterious natural sights the cave presents, there is also projection mapping fusing the ancient with the near future. The cave has even been set up with Wi-Fi!

Put on a headlight and try the adventure course which takes you through parts of the cave so narrow you need to almost crawl to get through! Note that you do need to book in advance to go on the adventure course.

Adjacent to Ryugado cave is the Rare Birds Center where you can see onagadori (lit. long-tailed cock), a bird designated as a Japanese National Natural Treasure.
