First of all, the outdoor bath (Rotenburo) is simply awesome. Roaring river nearby, 4 baths, I've not seen better. Will definitely be back. The grounds around the onsen are very fun as well. The room was antiquated but not why I came. Reminded me of my Japanese grandmother's place back in the 80's. Charming in it's own way, but may not be for everyone. I missed the last shuttle bus so it was a $100 cab ride to the onsen, but took the shuttle on the way back. Got breakfast and dinner were included (I got full board), but only ok. No other food options apparent. There is a lunch place across the river (3 minute walk) where you have to buy your lunch, which is inexpensive and of good quality (better than breakfast and dinner IMHO)
