If your in Kami area Ryugado cave is worth a visit if you have a spare hour or two.
Plenty of parking.
Escalator to the ticket office or stairs if your fit.
1200 yen entrance fee.
Free guide books in English.
It's about a 1km walk through caves.
Narrow path all the way.
Well lit, with handrails and a few steps. If you have a good torch as well, you will light up some of darker places in the cave.
Sometimes you have to turn sideways and breathe in to get through gaps. One part I crawled a few metres.
Bit slippery in some places.
Last part of cave is a few stairs, when your heading towards Heaven.
When you reach the top exit, it's a nice walk down.
Souvenir shops and some eating places there.
I like the cave because it was narrow and windy.
Lots of stalactites and stalagmites.
Well worth a visit.
We visited the cave on a rainy day. Not much people there and we could enjoy the cave by ourselves. Interesting limestone cave with bats flying overhead. Very interesting to see the little museum what was found there and how the cave was made by thousands of years!
We did an extra adventure course. Requires reservation and Japanese speaker but kids loved it. There are two different adventure courses hence we want to try the different one next. And yes there are centipedes and bats 🦇
