The Japanese-style Iya Onsen Hotel is a retreat nestled in Iya Valley, one of Japan's three most mysterious places. The scenery of the precipitous cliffs is as beautiful as a painting. In the season of autumn leaves, the emerald-colored river waters and the mountains form a natural and beautiful brocade. During the season of fresh green leaves, the valley is decorated with vibrant trees.

Hotel Iya Onsen boasts an open-air bath where you can enjoy this magnificent view. A cable car takes you 170 meters down to the valley floor, where you can enjoy the panoramic view as you slowly descend the 42-degree cliff. The open-air bath is built so that it enters into the flow of the Iya River, and is a rare hot spring in Shikoku with its own spring water flowing out of the hot spring.
