One of Japan's Three Most Secluded RegionsThe Only Hotel in Iya Valley: Iyaonsen

This gorge, with its sheer cliffs that cut through the Shikoku Mountains,
has a dangerous beauty that is hard to match.
In autumn, the red leaves combine with the sparkling emerald water below to create a rich, natural tapestry.
When new leaves begin to appear in spring, the valley pulses with vibrant green life.
Expansive vistas of Iya Valley can be viewed from our hotel's open-air baths.
