This cave in the Akiyoshidai Plateau is the largest limestone cave in Asia. With an average height of 30m, it stretches about 10km plastered all over with natural limestone, 1km of which is open to the public. The plateau was once a coral reef and has been gradually eroded by rainwater over millions of years, resulting in the landscape called karst topography.
The iconic spot here is Golden Pillar, a giant yellowish column with vertical streaks, 15m tall and 4m wide. Other types of natural carvings include numerous water-filled limestone terraces, cone-like pillars as large as 5m in diameter, and the vast ceiling of icicle-like formations. The underground river is flowing and you need a good pair of walking shoes. About 10 minutes on foot from the elevator exit, there is an observation deck to offer a good view of the plateau.

Absolutely amazing sightseeing event.
They started work on this cave in 1925 with a few electric lights, and now they have a complete concrete walkway with high tech lights and sound for info in 5 different languages along the way.
It's kind of like walking through a James Bond movie set!

Nice and cooling place to visit during the summer season. My 3 kids had such a great time exploring the cave. I felt the pinch that tourists do not enjoy the 700 yen rate anymore but need to pay the full price which is quite expensive. I was told they just took away the 700 yen rate in April 2019.

After sightseeing so many shrines and temples in Japan, I was so happy I discovered this spot. The cave is Japan's biggest cave. In the cave you will see a unique world of structures and animals. A must visit if you are travelling in Yamaguchi Prefecture.
