We stayed at Nishiyama Onsen on 21/November night. There is a lot of hot springs, and mountains in Nishiyama. Off course, we stayed the Japanese style inn with hot springs. We enjoyed the hot spring, local foods, and local Japanese Sake. It was nice place to stay in Nishiyama-Onsen. I highly recommend it.
In the photo above, it's a hot spring bath tub making Japanese cypress.
