  • I went there about 30 years ago. The underground lake was very beautiful, and I had always wanted to go there, but there was not a chance easily, and it was able to be realized at last. It's better and easier to see, but it's no longer wild. But the beauty of the underground lake remained the same. And this time, we went to Ryusen Shin-dong Science Museum on the other side of the road. I'm on the ticket and I have time, so i went there by the way. However, even though it is right next to Ryusen-dong, the inside is completely different and it was very interesting. I don't know what time it will be next, but I want to go again.

  • It is said that it is the three largest cave salnook in Japan. Imagine Akiyoshi-dong and the aisle smaller and going up and down the stairs. It was regrettable that it was a little different from a selfish imagination.
