The best place in Japan where we slept. Ryokan staff is simply beautiful, kind, very familiar ambient. They came to wait us to the train station without asking them, and they took us to the monkey snow park by car because it was raining! Japanese style breakfast was delicious (oishii!) and they have a private onsen where you can stay as long as you wish. A++
Stayed at Seifu-so, Yudanaka Onsen, Nagano.
