In Iya Valley, the Iya River flows from Mount Tsurugi and runs through two main areas: Nishi Iya (West Iya) and Oku Iya (Inner or East Iya). West Iya is easier to reach with buses from Awa-Ikeda and Oboke Stations, while Inner Iya is much harder to get to since buses are very limited or don’t run at all.
To explore the valley comfortably, it’s best to rent a car. You can rent one in Awa-Ikeda, Oboke, Takamatsu, or Tokushima. Just be careful—the roads are narrow, with sharp curves that can be tricky to drive. Buses from Awa-Ikeda and Oboke go to Iya Kazurabashi (some also stop at Iya Onsen) and Kubo, where you can transfer to go deeper into the valley. Buses to Mount Tsurugi only run on weekends and during busy seasons, not in winter.

1 of 2 in Tokushima Prefecture
The Iya Valley (祖谷渓, Iyakei) is a hidden gem in Tokushima Prefecture, nestled deep within the rugged mountains of Shikoku Island. Known for its stunning natural landscapes, the valley features steep slopes, deep gorges, and traditional vine bridges like Iya Kazurabashi and Oku-Iya Kazurabashi, offering a glimpse into Japan's past and breathtaking views. This secluded paradise also boasts relaxing hot springs and numerous outdoor activities for nature lovers and adventure seekers.
Beyond its scenic beauty, Iya Valley holds historical significance as a refuge for the Taira Clan, who fled here after the Gempei War in the late 12th century. Remarkably, descendants of these ancient clans remain in Iya and other secluded areas like Shirakawago and the Noto Peninsula, preserving the area’s unique heritage. With its blend of history, culture, and natural beauty, the Iya Valley promises an unforgettable escape into one of Japan's most enchanting landscapes.
