Jizō Onsen Spa JippukuNoYu

A large complex. Really a lot of stuff, let me go through it. At the center is of course the onsen with a huge rotenburo. No panoramic view, but there's a garden on a slope — beautiful. Barrel baths, baths set in big boulders, a sauna, an outdoor cold bath where you can sit for a long time. The water is alkaline at 9.4, but seems to be heated. The restaurant is fantastic! They roll and cut fresh soba right before your eyes, bake pizza in a wood-fired oven, there's a coffee shop by the fireplace, their own bakery, and a stand with delicious gelato. The little shop has Shinshu apples — 350 yen for 6!
