Dangyo Falls Springwater Complete Guide｜Exploring Shimane’s Top 100 Waters and Japan’s Top 100 Waterfalls in Oki
The Dangyo Falls springwater located in Naku, Okinoshima Town, Oki County, Shimane Prefecture is a miraculous famous water created by Japan’s nature. Selected as one of the “Top 100 Famous Waters” by the Ministry of the Environment in 1985 (Showa 60), and further designated as one of “Japan’s Top 100 Waterfalls,” it is known as a rare location that shines in these two prestigious selections across the entire country.
Located on Shimojima Island in the Oki Archipelago, this springwater is situated in the upper reaches of the Naku River, which originates from Mount Yokoo, and is formed by two waterfalls—the male and female falls—that cascade down from a majestic folding-screen-like rock wall. Since ancient times, the local people have revered it as the “Water of Longevity,” the “Water of Victory,” and the “Water for Fire Prevention,” making it deeply rooted in the life and culture of the people of Oki Island.
About Dangyo Falls Springwater｜Why It Was Selected as a Top 100 Famous Water
Value as a Top 100 Famous Water
The background for Dangyo Falls springwater’s selection as a Top 100 Famous Water lies in its abundant springwater volume and excellent water quality. The springwater volume reaches approximately 2,500 tons per day, maintaining stable water volume throughout the year. This abundant water flows as the Naku River and ultimately empties into the Japan Sea.
Rainwater that falls on the forested areas of Mount Yokoo slowly permeates through the geological layers over many years, emerging as clear water through nature’s filtration process. The water produced by this natural purification system contains appropriate mineral content while remaining pure and pristine, and has been used as domestic water by local residents since ancient times.
Geological Characteristics
The geology around Dangyo Falls is characterized primarily by volcanic rock unique to Oki Island. It has also been selected as one of the 100 Shimane Geosites by Shimane University, making it geologically valuable. The male falls have a drop of approximately 50 meters, while the female falls drop approximately 40 meters, and the sight of water cascading from the steeply cut rock walls like a folding screen is breathtaking.
These rock walls were formed by lava created through volcanic activity being eroded over long periods of time, and their unique topography serves as a factor in producing the abundant springwater.
The Two Falls of Dangyo｜The Charm of the Male and Female Falls
Characteristics of the Male Falls (Odaki)
Located on the right side, the male falls plunge dramatically from a height of approximately 50 meters with powerful impact. Also called “Urami Falls,” this waterfall is known as a rare “behind-the-falls” waterfall nationwide, where visitors can walk behind the waterfall and view the outside scenery through the water curtain.
When you enter behind the falls, you are surrounded by a water curtain flowing with a thunderous roar, as if you have wandered into a different world. The space enveloped in negative ions becomes a healing spot where both mind and body can be refreshed.
Characteristics of the Female Falls (Medaki)
Located on the left side, the female falls drop approximately 40 meters and are characterized by a somewhat more elegant and delicate water flow compared to the male falls. The sight of the two falls flowing side by side appears as if a husband and wife, making it popular as a power spot for matchmaking and romantic connections.
Dangyo Shrine is enshrined between the female and male falls, and the sight of the shrine standing as if protected by the two waterfalls creates an atmosphere truly worthy of being called a sacred space.
The Water of Longevity and Victory｜Traditions and Beliefs of Dangyo Falls Springwater
Connection with Oki Island’s Traditional Events
Dangyo Falls springwater is deeply revered by local people as the “Water of Victory” and the “Water of the Goddess.” Particularly during traditional events such as Oki’s famous bull fighting (sumo wrestling) and classical sumo tournaments, participants would always drink this waterfall’s water to purify themselves—a custom that continues to be passed down today.
This custom is based on the ancient belief of incorporating the sacred power residing in the waterfall’s water into one’s body and praying for victory. In the island’s important events, Dangyo Falls springwater has become an indispensable presence.
Reputation as the Water of Longevity
Known as the “Water of Longevity,” Dangyo Falls springwater has supported the health and longevity of local residents since ancient times. Oki Island is known for having many long-lived residents, and one factor attributed to this is the daily consumption of this clear water.
The water quality with excellent mineral balance and the pure, clean taste resulting from nature’s filtration process that removes impurities is evaluated as ideal drinking water for maintaining health.
Belief in the Water for Fire Prevention
Furthermore, Dangyo Falls springwater is believed in as the “Water for Fire Prevention,” and there was a custom in the past to take this water home when building a new house or to prevent fires as a protective charm. Due to the purifying power of water and the fact that it springs from a sacred location, it was believed to possess the power to ward off calamities.
Dangyo Shrine｜A Sacred Realm United with the Falls
History and Origins of the Shrine
Dangyo Shrine, enshrined between the two falls, forms a sacred space united with Dangyo Falls. The approach path is lined with old cedar trees said to be several hundred years old, and their branches spread to cover the sky, creating an fantastical atmosphere like a forest inhabited by spirits.
As you walk along the approach path leading to the shrine, you are enveloped in a mystical space woven together by dappled sunlight filtering through the cedar trees and the sound of falling water. This approach itself has become a power spot, captivating many pilgrims and tourists.
Tips for Visiting
When visiting Dangyo Shrine, the custom is to first purify your hands with the fall’s water before proceeding along the approach. From the shrine grounds, you can view both falls simultaneously, and praying enveloped in the sound of water provides a purifying and refreshing experience.
Early morning visits are especially recommended, and the sight of the falls in the morning sun is divine, offering the clear energy befitting the beginning of a day.

Surrounding Vegetation and Forests
The forested areas continuing from Mount Yokoo are covered with vegetation unique to Oki Island. The rich forest where broadleaf evergreen forests and coniferous forests intermingle functions as an important water source forest that nurtures the springwater.
