  • This is the entrance of ryusendo. Buy tickets at vending machines. 1000 yen. Ryusendo entered. Totally different if she had expected Akiyoshi-do cave scenery! Ryusendo underground lake called Lake. Rimstone in large icicles are very helpful. Don't have much time, so had turned quickly. Few tourists.

  • The cave is not like the typical caves that I’ve seen here in the Philippines. Upon entering you’ll never know that it is a cave. It has blue lights that reflects the depth of the waters. It has alot ...  more »
  • I visited as a place second to none rain knowing weather when I went to Iwate. During the week of the season was very empty cave, slow tour. Also the difference between the air staff do not feel so seasonal patterns, clothing, but cold required is when the cave tour. Slippery footing because shoes are recommended (* be ∇ ') can look quite high up on the stairs (up and down stairs are tough people and...), clean and crystal-clear water, was as mysterious.

  • The cave itself was cool. However coming from Morioka, the only public transit option was a bus that took 2.25 hours and 2660¥ one-way. It also travels infrequently, so check the schedule. Renting a car might have been better. The cave is somewhat small as far as caves go, you can walk through it in 30-40 min with stopping a lot to take pictures. There is also a second cave that has more of a museum feel which is neat. Both caves have really cool looking formations and underground lakes.
  • Fun place to visit but very out of the way. Food options are not great either.
  • Nature at its best. Experienced the cool (literally) limestone caves and the breathtaking view of cave lakes
  • Cave was good but at places where water would drip they had a lot of plastic sheets to keep you dry but I thought they were a huge eye sore. Very nice area around cave as well. Make it part of a road trip and it is worth the drive.
  • This place is very interesting. The cave is large, with a few separate levels. Many small spaces and lots of stairs, but manageable. The cave is lit with many color changing lights that creating a good atmosphere. There are a couple small cafes and a restaurant on the property as well.
