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.

Awesome experience. A must visit spot if you love caves. Actual cave is about 9 km long but the tourist admission is just for 1 km. They have adventure course if hiking is your kind of thing.

This was my second time. It's pretty chilly down in the cave even in the summer. A light jacket would be helpful. They have a box that translates in English and a few other languages, serves as a guide to better navigate the cave.

It's an awesome place to go for a day trip! Keep in mind there are three places to enter/exit the cave. You can go to the top of the mountain and walk down, the bottom and walk up, or the middle and take an elevator down. Beautiful place that offers both Japanese and English paper/sound guides.

Amazing cave. In total about 1000m long, divided into 2 parts. You can start at either end. It's been modernized and lit so that it isn't dark. There are no bathrooms inside, so make sure you go before you enter (either entrance has restrooms).
If you listen you can hear the bats above you, we noticed a few of them as we went through.
There are handrails on most of the walk, but it is wet, so wear shoes with good grip. We went in the summer and we weren't that cold just wearing long 👖 jeans and T-shirts.
There are various explanations recorded in English, Japanese, Korean, and Chinese at stops, just click the green button for the audio you want. All the signs are bilingual Japanese and English. There are signs at the gates in English, too.
Parking is more expensive the closer you get. We parked a bit out (only 6 min walk) for only 200 yen.
