Guida
Located in the Iya region of Tokushima Prefecture, the "Iya no Kazurabashi" is a traditional suspension bridge crafted by weaving together mountain vines known as shirakuchi-kazura. Measuring 45 meters in length and 2 meters in width, the bridge features gaps in its flooring, allowing visitors to peer directly down into the valley below. This unique structure causes the bridge to sway as you walk, providing a visceral connection to the natural terrain. It is designated as a National Important Tangible Folk Cultural Property, representing a precious cultural heritage where Japanese traditional architectural techniques and nature seamlessly blend.
This area is steeped in legend, said to be a place where the Heike clan fled to escape pursuers after losing the Battle of Yashima. Various legends surround the origin of the bridge: one story suggests the Heike warriors built it so they could quickly cut it down to evade enemies, while another claims the monk Kobo Daishi (Kukai) built it for the local villagers. In this secluded region, which remained isolated from the outside world until modern times, ancient lifestyles and unique customs continue to be cherished and preserved.
The greatest thrill is the experience of crossing the bridge itself. Looking through the gaps of the woven vines toward the valley floor provides a sensation unlike any other. Near the bridge, you can also enjoy the beauty of the "Biwa Waterfall," which drops approximately 40 meters, showcasing the magnificent sculpting of nature. Furthermore, depending on the season, the area is adorned with blooming wisteria flowers, creating a stunning contrast with the fresh greenery and the surrounding mountains.
The scenery changes beautifully with each season. From spring to summer, the lush greenery and wisteria flowers (mid-April to early May) offer a rich palette of natural colors. At night, a mystical illumination takes place between 19:00 and 21:30. While the bridge itself cannot be crossed during the illumination period, it offers a truly enchanting sight to behold. We recommend visiting during the day for the physical thrill of the crossing, and visiting at night to enjoy the ethereal atmosphere.
Beyond crossing the bridge, you can fully immerse yourself in the surrounding nature. For instance, walking about 50 meters to the left of the bridge leads you to the powerful Biwa Waterfall. There is also a walking path that leads down toward the Iya River, allowing you to experience the pristine river water (please note that setting up tents on the riverbanks is prohibited). It is a perfect place to experience history and topography through all five senses.
The area surrounding the bridge is the Iya region, known as a hidden gem of Tokushima. The landscape is dotted with traditional villages, hot spring facilities, and historic houses. While traveling by car is the most common method, access via bus is also possible. There are many spots nearby where you can feel the original, untouched landscapes of Japan.
Because the bridge structure is unstable, we highly recommend wearing comfortable walking shoes. Cashless payments are accepted for admission. No advanced reservation is required, but please check in advance as the site may temporarily close during heavy rain or extreme weather warnings. To protect the natural environment, please take your trash home with you and refrain from activities outside of designated areas.
