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.

Bring your passport and get discount for entrance ticket. You also can enjoy orange summer ice cream and pear ice cream, really delicious! Natural landscape is really beautiful, inside the cave also can try adventure program by paying additional cost fee. Anyway, just go here first and explore the uniqueness of this cave!

An amazing place. The largest and deepest caves in Japan. Well worth a visit. Need to be careful walking around as lots of steps and slopes so not easy for the disabled or older people.

I've been in a few different caves now and this was my favourite, mostly because of the fresh running water which goes through it.
There's plenty of information inside about the various sites (mostly calcium formations). Just press a button on a machine and the information will be told to you.
The cave is about 1km long and takes maybe a little over an hour to get through. Though if you park your car on one side rather than using public transport, you'll have to walk back again.
It costs 1200 yen for an adult. If you're a foreigner and you can show your passport, it's just 700 yen! It's so nice to be in an Asian country where they don't charge foreigners more than that locals. I didn't have my passport, but I had a photo of it. They accepted this but I would still recommend bringing your physical passport just to ensure the discount.

Worth going to yamaguchi to visit the cave. It's quite a far walk but worth spending some time in the area!

Long and spacious cave. The internal part has path that would make walking quite easy but still be careful as some part is slippery. Make sure you keep your entrance ticket as you need it for re-entry if you go up the escalator to see the hill with rocks.
And since you've come this far, if you're driving, do visit Hagi to see samurai houses and nice sea side panaroma.
