Karukaya Sansō

Hotel in Shin-Hotaka Onsen

The tatami rooms at this friendly riverside inn with lots of open space to explore are clean, tidy and unexceptional, but for the better ones, which have lovely views. The enormous konyoku rotemburo (mixed-bathing outdoor baths), claimed to be the largest in Japan, are remarkable. However, add in the sweeping mountain views and they're quite extraordinary.

Campsites (adult/child ¥3000/1500) are available or you can come just to use the rotemburo (¥600; 10am to 3pm).
