What to know
The Iya Valley (祖谷渓, Iyakei) is a remote, mountainous valley in western Tokushima Prefecture. Nestled in the heart of Shikoku Island, this secluded valley features steep mountain slopes and deep rocky gorges, historically crossed by vine bridges. Three of these bridges—Iya Kazurabashi and the Oku-Iya Kazurabashi bridges—are still maintained today and remain top attractions. Iya is also known for its hot springs and outdoor activities.
Due to its isolation, the valley served as a refuge for members of the Taira Clan who fled here after losing the Genpei War (1180–1185) at the end of the Heian Period. Their descendants can still be found centuries later in the Iya Valley and other remote regions of Japan, such as Shirakawago, Yunishigawa, and the Noto Peninsula.
