The oldest inn on the Kiso Road, the Iwaya is a traditional Japanese lodging with rooms furnished in cypress wood and tatami flooring. The hotel’s baths, which are sourced from the nearby Yoshinaka spring, historically are the best way to relax after a long day on the Kiso Road.


Positioned on the Kiso Road, the Iwaya has long benefited from a broad range of dishes that travel the road with their creators. Famed for its mushrooms in autumn, the Iwaya also offers traditional Japanese fare cooked with local seasonal ingredients to create delicate, charming and rustic dishes.


Its position on the Nakasendo Trail means the Iwaya is ideally located to explore features of the trail itself, which is renowned for its diverse beauty and fantastic examples of Edo-era architecture. The Jigokudani Monkey Park is also easily reachable, where guests can view the snow monkeys in their natural habitats in the hot springs.
