This article comprehensively introduces the charm of this famous water, from its historical background and water quality characteristics to actual usage methods, access information, and nearby tourist attractions.
Kannon Sacred Water | The Famous Water of Ryugen-ji Temple That Has Flowed for Over 450 Years
Kannon Sacred Water is natural water that springs from the grounds of Ryugen-ji Temple located in Wada, Minami-Shinsui, Iida City, Nagano Prefecture. The clear water that flows from the foot of Seihei Mountain, the only independent peak in the Toyama region located at the southernmost tip of the Southern Japanese Alps, has continued to flow for over 450 years without ever running dry.
Selection as One of the Heisei 100 Best Waters
In June 2008, it was selected as one of the “Heisei 100 Best Waters” by the Ministry of the Environment. This was the second selection following the “100 Best Waters” selected in 1985, with precious water resources chosen from across the nation. In Nagano Prefecture, besides Kannon Sacred Water, four locations in Shinshu were selected as famous waters: “Matsumoto Castle Town Spring Water Group (Matsumoto City),” “Kiso River Source Village Mizuki-sawa (Kiso Village),” and “Ryuuokoji Clear Water (Kijima-dai Village).”
Historical Connection with Ryugen-ji Temple
Ryugen-ji is a Soto Zen temple deeply connected with the history of the Toyama region. The temple grounds also contain a giant tree called “Kannon Great Cedar” with a tree age exceeding 400 years, telling of this place being an ancient place of worship. The name Kannon Sacred Water derives from Kannon worship and has long been cherished by local residents.
Water Quality Characteristics of Kannon Sacred Water | Mineral Balance at the Top of Japan
The reason Kannon Sacred Water is supported by many people lies in its excellent water quality. Let us examine in detail the characteristics revealed through scientific analysis.
Hard Water with Hardness of 225.5
The greatest characteristic of Kannon Sacred Water is its hardness of 225.5. While most natural waters in Japan are soft water (hardness of 100 or less), Kannon Sacred Water is classified as hard water. This hardness indicates extremely high levels of calcium and magnesium content.
Abundant Mineral Components
Kannon Sacred Water contains the following mineral components in abundance:
- Calcium Ions: Minerals essential for bone and tooth formation
- Magnesium Ions: Important components involved in enzymatic reactions in the body
- Bicarbonate Ions: Works to regulate pH balance in the body
These minerals are created through a process where water from the Ikeguchi Peak water vein originating from the Southern Japanese Alps slowly dissolves limestone layers (geological strata that were once oceans) over decades. This geological process creates the unique mineral balance of Kannon Sacred Water.
Slightly Alkaline Characteristics (pH 8)
Kannon Sacred Water exhibits slightly alkaline pH values around 8. Since human body fluids are also slightly alkaline, it is said to be easily compatible with the body. Additionally, the water temperature remains stable throughout the year at 14.0-15.0°C, maintaining a cool and easy-to-drink temperature.
Japan’s Highest Mineral Content
Kannon Sacred Water is noted as “Natural Mineral Water with Japan’s Highest Mineral Substance Content.” This balanced mineral composition has value equivalent to natural supplements and is particularly supported by health-conscious people.
Taste and Usage Methods of Kannon Sacred Water
Mouthfeel and Deliciousness
You might think hard water would be difficult to drink, but Kannon Sacred Water is praised as having “a clean, mellow mouthfeel that goes down smoothly.” Despite being rich in minerals, it is characterized by a clear, refreshing taste without any unpleasant flavors.
Water Collection Method and Precautions
A water collection area is equipped within the temple grounds where anyone can freely collect water. On weekends, so many people visit from outside the prefecture that lines form.
Precautions when collecting water:
- Prepare Containers: Bring clean plastic bottles or water containers
- Spirit of Sharing: Be mindful of other users during crowded times
- Environmental Conservation: Always take trash home and keep the water collection area clean
- Storage Method: Store collected water in a cool, dark place and use it as soon as possible
