Ōtaki Limestone Cave Guide: Cool Things to Do in Gujō-Hachiman
See Natural Limestone Formations Up Close
Ōtaki Limestone Cave (Ōtaki Shōnyūdō) is a sightseeing limestone cave located in Akuta, Hachiman-chō, Gujō City, Gifu Prefecture.
It is well suited to travelers who want to add a nature experience different from strolling the town of Gujō-Hachiman.
As you walk through the cave, you can observe limestone formations and scenery created by underground water over a very long time.
The total length is about 2,000 m, of which about 700 m is open to the public for sightseeing.
Another appeal is being able to refresh yourself in the cool underground space of about 12 to 14°C in the middle of a trip touring temples, shrines, and old townscapes.
Top Things to See at Ōtaki Limestone Cave for International Travelers
At Ōtaki Limestone Cave, you can view the limestone formations spreading across the ceiling and walls as you make your way along the roughly 700 m of open passage.
Deep inside the cave is an underground waterfall with a drop of about 30 m, where you can feel up close the atmosphere created by the sound of water and the rock surface.
This underground waterfall is located deep below ground and is the origin of the cave's name.
It is an easy spot to recommend not only to those interested in Japan's natural scenery but also to those looking for a place that stays cool even in summer.
The Ōtaki Limestone Cave Experience Begins with a Wooden Cable Car
Enjoy the Wooden Cable Car Ride to the Entrance
One distinctive feature of Ōtaki Limestone Cave is the wooden cable car heading to the entrance, a rarity even in Japan.
As it climbs gradually while you take in the mountain scenery, you can enjoy a feeling like a small adventure even before entering the cave.
Reaching the entrance by this ride is an experience that tends to leave an impression on family trips and trips with friends alike.
However, please follow the guidance on the day regarding operating status and the reception process.
Inside the Cave, the Basic Rule Is to Proceed Calmly Along the Route
The inside of the cave is maintained for sightseeing, but it is a space that makes use of the natural terrain.
Watch your footing and overhead, and proceed along the route without rushing.
Limestone formations are natural objects created over many years, so it is important to view them without touching.
In narrow spots, keep your distance from those in front and behind, and when taking photos, be careful not to block the passage.
How to Explore the Limestone Formations and Underground Waterfall
Observe the Rock Surface of Limestone Lit by the Lights
Inside the cave, paying attention to the shape, color, and surface texture of the limestone makes the tour even more enjoyable.
Some formations hang from the ceiling like icicles, some rise from the ground, and some spread across the walls, each with a different appearance even within the same cave.
In dark places, pausing for a moment until your eyes adjust makes the bumps in the rock and the flow of water easier to see.
Take In the Sound and Air of the Underground Waterfall
The "otaki" (great waterfall) in the name of Ōtaki Limestone Cave comes from the underground waterfall deep inside the cave with a drop of about 30 m.
The sound of falling water, the damp air, and the echoes reverberating off the rock give a different impression from an outdoor waterfall.
Rather than only taking photos, pausing quietly to listen to the sound lets you feel the character of the underground space.
When it is crowded, viewing while being considerate of others makes for a pleasant visit.
