    For cave system is like a little scared. Inside the cave were lots of visitors, so inside the cave is prepared to jam. Underground lake is beautiful, but I'm afraid. But those who don't own feet won't overdo it, that stick up and down fine, intense, so may be better

    The summer holidays so crowded. Go dressed like a windbreaker, just by the sheer long sleeve cold enough in the falling drops of water there, so I hope it is. Wet feet too. Worth a look is.

    It was just before you die also cave-like and always want to go. It was making plans to go in the fall of last year by Typhoon No.10 of August great damage received can visit had gone happily March safely resumed business, went to the end of July. And the remaining damage from Typhoon en route from Morioka to iwaizumi in several places during the construction and the really big disaster was felt so hurt. Went to the site and worrying about whether or how ryusendo damage at the same time and it was just previously recovered similar was being revived splendidly. Underground lake couldn't be in the beauty of imagination over while moving from in-situ. Fortunately visitors who did not so much to take sinus 2 laps and, I spent nearly two hours. I think that beauty is not interested in the cave also worth a look is great. Take also day whether you want to visit.

    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.
