Located on a precipice in the Iya Valley, the Shomen Kozō is a sculpture standing upon a rock overlooking a deeply carved V-shaped valley. This location, looking down upon the shimmering emerald green waters of the Iya River, creates a unique landscape where natural beauty and man-made art become one. It is said that the sculpture was inspired by local legends of children and travelers who once tested their bravery on these very rocks.
This site holds a storied history; local legends tell of travelers and youths who performed feats of courage on the steep cliffs. The sculpture currently standing there serves as a symbol of this cultural heritage and the rugged spirit of the region. The terrain itself, featuring a protruding rock formation, was shaped during the construction of the old Iya road, making it a place where local folklore has taken a physical form.

The greatest attraction is the striking contrast between the tiny figure of the Shomen Kozō and the massive, steep cliffs overlooking the emerald green river. Looking down into the deep V-shaped valley, the clarity and color of the water are mesmerizing. The juxtaposition of the harsh, natural landscape and the small, solitary sculpture makes this one of the most iconic views in the region.
The expression of the valley changes beautifully with the seasons. In autumn, the entire mountain range is dyed in vibrant hues of red and gold, offering a spectacular view of the colorful foliage against the emerald river. Throughout the year, visiting during bright daylight hours is recommended, as the sunlight enhances the transparency of the river and clearly defines the height and depth of the cliffs.
Visitors can experience the sheer majesty of nature through sight. While gazing at the sculpture on the cliff, one can reflect on the sense of awe and the legendary tales of courage that travelers once felt. It is an ideal spot for photography and for taking a moment of quiet rest while absorbing the profound natural surroundings.
The area is part of the broader Iya region, known as one of Japan's three most important hidden valleys. Nearby attractions include the famous Iya Kazurabashi (Vine Bridge) and Biwa Falls. Exploring these sites together allows for a deeper connection to the culture and nature of Tokushima. There are also various hot spring facilities and accommodations nearby to enjoy a relaxing stay amidst the valley scenery.
As the terrain involves steep cliffs and uneven surfaces, it is highly recommended to wear sturdy, non-slip walking shoes. Please respect the natural environment and prioritize safety at all times, as the area is quite rugged.
