Ryusendo Cave

hi :)
i come for 2 nights to marioka in april,
i think of going to see the Ryusendo Cave .
it will have the jr pass.
however -it is more then 2 hours away(by bus), i hesitate if it is a waste of time or the cave is very very beutiful and worse the time wasted on driving.

what do you think?

thanks

Not sure whether you are aware of it, but the JR bus between Morioka and Ryusendo is covered by the Japan Rail Pass (it is not covered by other JR passes):

If you have an interest in caves, I think it can be worth it. It is one of Japan's nicer caves. Unfortunately, there isn't too much else to see in the immediate proximity of the cave. The scenery along the way is quite nice.

thank you! yes, i noticed, but for some reasons i will have the regular pass so that will be ok.
is there something special about this cave? or a day to lake tazawa is more recomended?

This page provides an introduction to the cave:

It depends on your personal interests. I personally never found Lake Tazawa too interesting. I recommend to read about both places and then make a decision on which one appears more interesting to you personally.

an hard choice ! however thank you :)

I'd definitely say Ryuusendou in a heartbeat, though I must admit I'm biased - it just reopened for business after it suffered quite a bit of damage in the typhoon that struck Iwate last August, so it (and Iwaizumi, where it's located) could certainly use a little more help in getting back on its feet. That aside, I've been there, and it really is quite pretty inside, although be prepared to spend an entire day getting to and back from Ryuusendou if you do decide to go there. The same could probably be said about Tazawa-ko though, although you do have Kakunodate nearby should you want to explore other tourist sites.
If I'm not wrong there're only four buses a day that head to Ryuusendou from Morioka, so you might want to plan your timetable for that day a little more carefully.
