This article comprehensively covers everything you should know before visiting Shiroshio Inari Shrine’s springwater pond, from its historical background and water quality characteristics to water collection methods and nearby attractions.
Ikkanda Springwater | A Treasure of the Hadano Basin Springwater Group
Ikkanda Springwater is a natural springwater located in Ikkanda, Serizawa, Imaiizumi-cho, Hadano City. As the place name suggests, this land has been known since ancient times as a region blessed with abundant water.
Part of the Hadano Basin Springwater Group
The Hadano Basin is a basin-shaped geography surrounded by the Tanzawa Mountains, where rainwater falling on the mountains infiltrates the ground and emerges at the basin’s periphery, creating a distinctive hydrological environment. Selected as Japan’s 100 Famous Waters by the Ministry of the Environment in 1985, the Hadano Basin Springwater Group comprises approximately 60 springwater points, with Ikkanda Springwater being one of the most abundant among them.
Abundant Water Volume of 5,000 to 7,000 Tons Daily
The Ikkanda district, where Shiroshio Inari Shrine is located, is blessed with abundant springwater of 5,000 to 7,000 tons daily. This volume is equivalent to the daily water usage of approximately 10,000 households and serves as an important water source for Hadano City. The clear water flowing through the shrine grounds has supported people’s lives since ancient times and made rice cultivation possible, serving as the water of life.
Water Quality Characteristics of the Springwater
Ikkanda Springwater possesses characteristics unique to natural water that has permeated through the Tanzawa geological strata over many years. It contains an appropriate amount of minerals such as calcium and magnesium, making it a soft to moderately hard water that is smooth and easy to drink. Notably, the nearby Tsurugashima Hot Spring is known for one of the world’s highest calcium content, reflecting the geological characteristics of this region.
The water temperature remains stable at approximately 15-17 degrees Celsius year-round, exhibiting the characteristic property of springwater where it feels cold in summer and warm in winter. This stable water temperature and abundant water volume maintain the rich natural environment within the shrine grounds.
History of Shiroshio Inari Shrine and Its Relationship with Springwater
Shiroshio Inari Shrine and Ikkanda Springwater have an inseparable deep relationship. The shrine’s founding and the existence of springwater convey ancient water-related beliefs to the present day.
Ancient Rice Farmers and Water Source Worship
For the ancient rice farmer populations who inhabited this land, water sources essential for rice paddy cultivation were literally the source of life itself. Recognizing the sacred in the “water source (minamoto)” that became the foundation of human survival and the source of clothing, food, and shelter, ancient people revered it as a place where gods dwell (shinamboi).
The origin of Shiroshio Inari Shrine lies in enshrining “Uka no Mitama,” the spirit of rice and grain that oversees the water necessary for rice cultivation. In other words, the existence of springwater was the fundamental reason for the shrine’s founding, with gratitude and reverence toward water forming the origin of its faith.
Edo Period Reconstruction and Changes in Names
In the early Edo period, the shrine used the characters “white reed (shiroshino).” In 1774, to clarify its origins and renew faith, the shrine was reconstructed through a transfer from Fushimi Inari Taisha in Kyoto. It is believed that the name was changed to the “Shiroshio” characters at this time.
Following its reconstruction, Shiroshio Inari Shrine became widely worshipped as one of the three great Inari shrines of the Kanto region and has welcomed many visitors alongside its abundant springwater.
Importance as a Water Source
Following modernization in the Meiji period onward, Ikkanda Springwater was positioned as an important water source for Hadano City. Today, it continues to be utilized as part of Hadano City’s tap water source, and the springwater within the shrine grounds continues to support the lives of local residents.
The shrine grounds where pure water springs forth represent a truly “clean and spiritually pure place worthy of enshrining the gods,” maintaining unchanging value from ancient times to the present day.
Springwater Spot Pilgrimage Through the Shrine Grounds
Within Shiroshio Inari Shrine’s grounds, there are multiple springwater-related spots, each with its own characteristics and points of interest.
Temizusha (Water Purification Basin) Springwater
As you proceed along the approach path, the first thing you encounter is the temizusha. While many shrines use tap water, the temizusha at Shiroshio Inari Shrine carries Ikkanda Springwater, allowing visitors to purify themselves with natural springwater.
The water in this temizusha is potable, and many visitors bring plastic bottles to collect water. The cold, clear springwater has a subtle sweetness when tasted, embodying the spiritual purity befitting the shrine grounds.
The Golden Spring (Hikariomo Pond)
The most mystical spot within the shrine grounds is the “Golden Spring (Kogane no Izumi).” This pond is home to “Hikariomo,” a rare type of algae, and under the right conditions, the water surface appears to shimmer with golden light, attracting attention as a power spot for fortune in money.
Hikariomo can only grow in clean water environments like springwater and is a delicate organism. The sight of the pond’s water surface shimmering with golden light depending on the angle of sunlight and weather conditions is truly mystical and captivates many visitors. The late morning hours when slanting light filters through are said to be the best times to observe the golden shimmer.
Springwater Ponds and Water Channels
Within the grounds are multiple springwater ponds from which flowing water becomes a small stream that circulates through the grounds. In the transparent water, aquatic plants sway, and small fish can occasionally be spotted.
Near the spring outlet, you can observe water welling up, allowing you to experience firsthand the natural phenomenon of water emerging from underground. The surrounding area is enveloped in greenery, with the pleasant sound of running water creating a soothing space.
