Kobo Pond | Basic Information and Origin of the Name
Kobo Pond (kouboouike) is a water spring located in Kamashomizu-cho, Hakusan City, Ishikawa Prefecture. It is also called “Kamashomizu” or “Kama Pond,” and this name is also the origin of the area name “Kamashomizu-cho.”

Showa Famous Waters 100 Selections | Significance of Selection
The “Showa Famous Waters 100 Selections” were selected by the then-Environment Agency in March 1985 (Showa 60) as outstanding spring waters and river waters from throughout the country.

- Kowa Shuizui (Kawachi-cho, Hakusan City)
These famous waters are deeply intertwined with the history and culture of their regions and have been a precious water resource supporting the lives of local residents for many years. However, selection for the Famous Waters 100 does not guarantee suitability for drinking, so caution is necessary when using it.
Kobo Daishi Legend | The Miraculous Story of Water Springing Forth
Kobo Pond preserves an interesting legend related to Kobo Daishi (Kukai).
Content of the Legend
Long ago, when Kobo Daishi was traveling throughout the country as an itinerant monk, he encountered a kind elderly woman in this area. The woman warmly received the traveling monk Kobo Daishi, providing him with food and a place to rest.
Deeply grateful for the woman’s kindness, Kobo Daishi wanted to repay her. Learning that this region lacked water and its residents struggled to obtain it, Kobo Daishi thrust his staff (shakujo) that he was holding into a rock. Then, clear water began to spring forth from that spot, and from that time on, abundant water has been brought to this land.
Significance of the Legend
While legends of Kobo Daishi related to water exist throughout the country, they are not merely folk tales but demonstrate how precious and sacred spring water has been treated in regions with scarce water resources. The legend of Kobo Pond tells of the local residents’ gratitude for water and their history of carefully protecting this spring water.
Rare Pothole Spring Water Nationwide | Geological Features
The greatest feature of Kobo Pond is the spring water flowing from a pothole (ouketsu), an extremely rare geological characteristic nationwide.
What is a Pothole?
A pothole (also called a pothole or pot hole) is a circular or elliptical depression formed on the surface of bedrock in the rapid flow sections of rivers. Small stones enter cracks in rocks at the river bottom, and as they rotate in the water flow, they continuously erode the rock, forming a pot-like depression.
Normally, potholes are landforms seen at river bottoms or banks, and the phenomenon of ground water springs flowing from them is extremely rare.
Geological Formation of Kobo Pond
The pothole at Kobo Pond is believed to have been formed through the following geological process:
- White Mountain Volcanic Activity: Volcanic activity of White Mountain forms a bedrock of rhyolitic composition
- Tegawa River Erosion: Intense flow of the Tegawa River erodes the bedrock, forming potholes
- Changes in River Channel: Over time, the river channel of the Tegawa River changes, and the pothole remains in its current position
- Ground Water Discharge: Ground water begins to spring forth from the bottom of the pothole
The Tegawa River is a primary river originating in White Mountain, and Kobo Pond, located in its middle course, is presumed to be a place where a former river bottom became dry land due to changes in the river channel.
Value as a Natural Monument
Due to these geological features, Kobo Pond has been designated as a natural monument of Hakusan City. The rare phenomenon of water spring from a pothole is valuable as a research subject in geomorphology and hydrology, and has scientific significance not only as a famous water but also academically.
Water Quality and Characteristics | Soft Water with Pure Taste
Kobo Pond water is classified as soft water, characterized by a mellow and easy-to-drink taste.
Water Quality Characteristics
- Hardness: Low hardness (soft water)
- Water Temperature: Stable at approximately 13-15°C year-round
- Transparency: Extremely high
- Spring Water Volume: Approximately 30 cubic meters per day, nearly constant year-round
Soft water is easy to drink for Japanese palates and is considered suitable for tea, coffee, and cooking. The constant water temperature year-round is also evidence that it springs from deep underground.
Historical Use
Until a simple water system was established in Showa 53 (1978), Kobo Pond water was used as a precious drinking water source for local residents. This water, which has supported the community’s life for many generations, is truly the history of the region itself.
