Just a side note, Hitou generally are big on traditions and onsen, but not necessarily luxury...(the price point should tell you as much!)
Nakanoyu has 3 buildings which by Hitou standards are very big 
One of them, Yake, is targeting hikers and climbers, with the lowest price, shared facilities, no lift etc, I heard the food is also different.
The one I booked, called Hotaka, is the mid tier. Have toilets in the room but no bathroom. Dinner is served in a dining hall.
The most expensive one, Kasumi, from what I can see, difference is the view, slightly larger rooms and also dinner is served in your room - I'm actually not a fan of this so easy decisions.
6 tatami room, futon was already set up.
