Iya Valley
Deep in the heart of Shikoku lies the Iya Valley, one of Japan's three 'hidden regions.' It is famous for its dramatic scenery of steep, forested mountains and the emerald-green Iya River. The valley's most iconic attractions are the Kazurabashi, or vine bridges, which were originally built by fleeing Heike samurai as a means to quickly cut off their pursuers. Walking across these swaying structures, made of woven mountain vines and wooden planks, provides a thrilling experience with views of the rushing water below. Adventure seekers head to the Oboke and Koboke Gorges for some of Japan's best white-water rafting and scenic boat tours. The valley is also home to remote hot spring resorts, such as the famous Iya Onsen, where a cable car takes guests down a 170-meter cliff to the baths beside the river. For a glimpse into traditional rural life, the village of Ochiai features a cluster of historic farmhouses built on nearly vertical slopes, now recognized as a national heritage site. The local cuisine features hearty Iya Soba (buckwheat noodles) and grilled river fish. Autumn is undoubtedly the best time to visit, as the mountain foliage turns into a striking tapestry of red and orange. Due to its remote nature and narrow winding roads, exploring the valley is best done by rental car, offering a journey back in time to a mystical and rugged side of Japan.
