C aving Explore the mysterious marble caves
What is Caving ?
Caving... is a coined word that combines the words "cave" and "ing" and refers to cave exploration. Hiraodai has about 200 caves that have been discovered, and it is an activity where both children and adults can get covered in mud and enter the earth's interior for a mystical experience. Hiraodai's caves are cool in the summer and warm in the winter, with temperatures around 15 degrees all year round , so you can enjoy them all year round!
*The regular caving program is for children in the third grade or above. There is also a challenge course for children under the third grade.

What kind of caves can you enter?
Mejiro Cave
The tourist area is about 200m long, and the rest of the cave is unvisited. It is one of the largest limestone caves in Hiraodai, with a total confirmed length of 2km. At the very back, there is a 20m waterfall, and you can see a spectacular view created by nature.


青龍窟(せいりゅうくつ)
Seiryu Cave is one of the largest limestone caves in Hiraodai along with Mejiro Cave. It is also a sacred place that was used as a training ground for Shugendo sect members in the past. It is a cave that inspires the spirit of exploration with its white marble river, varied topography, and various entrances.


Fudo Cave
Half of the entrance to this cave is submerged, and there is a lot of water inside the cave, with some parts forming lakes, so you can have fun swimming across them. At the very back, the cave splits into two, and a beautiful sandy beach and an underground lake spread out before you.


Senbutsu Cave
Senbutsu Cave is a very famous tourist cave. It is a very popular cave in the summer, where the lights are on for about 900m from the entrance and you can walk along a pleasant river. Beyond the so-called "Hell Tunnel" where the lights go out, there are a series of small waterfalls that you can explore.
