You may find a room at Kinosaki's largest inn even when other inns are full. Western- and Japanese-style rooms are pricey but well kept, and there are both Western and kaiseki (Japanese haute cuisine) restaurants. It's at the far end of town.
The jaw-dropping private spa rooms in Japanese, Balinese and Chinese style with large tubs, rock saunas and gorgeous garden views are a highlight here. Prices are steep (¥8640 for up to four guests, 70 minutes), but include water and sparkling wine, as well as appropriate attire.
