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.

It's beautiful here and there are discounts for overseas tourists. To explore, one needs to walk quite a fair bit. There is a direct bus from Shin-Yamaguchi Bus Terminal Platform 2.

As I entered they warned us we had a long way to walk to get back from the exit, so we decided to just walk through the cave and back.
The caves had so many interesting things, like a mini-Mount Fuji, rice fields, and other formations like bundles of rice.
It was a relaxing place to be on a hot summer's day.
