  • Visited ryusendo, bought 1000 yen ticket. Some places had a roof, water has fallen from the top. Ryusendo has seven underground lake, looks up the second it didn't look so not more than to go back to. It is a clear, blue water. On the size scale of the cave of surprise, towards the top also has a stairs.

  • In early August, I visited a family trip of the summer. Remain strong impression the blueness of the water of the underground lake, but for me, it was about 40 years Buri excursion since junior high school, meanwhile, saw in junior high school, and one day, I visited with my family and thought. Fall step caves within the day, air temperature exceeds the 30-degree heat, it was, and, as soon as the stake was wrapped, I felt very comfortable. Also, apparently it's Cave was visited also the new ryusendo ryusendo tours, walking, located just across the road, but here, in the junior high school student, published did not do too much memory, as ryusendo no measure, but with academic value, It was very interesting. Before you travel, four kids, "I don't want to go watch cave again!" And the fumes were, after the tour, "interesting! absolutely want to come again!" And was very happy.

  • Fantastic experience. The cave is beautiful. It's chilly inside so remember to bring a coat or jumper. We visited when it wasn't so busy so were able to take some lovely photos (tripods are allowed) Some of the stairs are steep and a couple of areas are a little bit of a squeeze but even a large man like me had no problems haha. Highly recommended.
  • Beautiful cave, very clean, some tight spaces to manuver through and many steps so plan accordingly. This was a quick trip, about twenty minutes to walk through and take pictures. Look around carefully and you will see bats hanging around!
  • It's a short tour, about 30 minutes. But it's also amazing natural wonder. The waters ridiculously clear and clean.
  • It was very enjoyable to walk and very well maintained. Cave lighting wasn't too disruptive.
  • Definitely a great day trip. Very pretty and well maintained.
