Kobo’s Sacred Spring (Ishikawa Prefecture) Complete Guide: History of Kobo Pond and Nationally Rare Pothole Spring Water
Kobo Pond (Koboike), which springs forth in Kamashimizu Town, Nomi City, Ishikawa Prefecture, is a famous water spot with legends related to Kobo Daishi Kukai and geologically distinctive characteristics that are rare nationwide. Also known by the alternative name “Kama Pond,” this spring water has been cherished by local people since ancient times and was selected as one of the Hundred Best Waters of the Showa Era. This article provides detailed explanations of the history, characteristics, access methods, and surrounding tourism information of Kobo’s Sacred Spring.
Kobo Pond: Overview of Ishikawa’s Celebrated Spring Water
Kobo Pond is a spring water site located in Kamashimizu Town, Nomi City, Ishikawa Prefecture, and as its name suggests, it originates from a legend connected to Kobo Daishi Kukai. This pond is not merely a spring but is characterized by the fact that water springs forth from a geologically extremely valuable “pothole (ouketsu),” a phenomenon unique in its own right.
A pothole is a pot-shaped depression created when the rapids of a river carve away bedrock over a long period of time. Normally, potholes form at the bottom of rivers, but at Kobo Pond, groundwater springs forth from this pothole, making it an extremely rare phenomenon known nationwide. From this unique shape, it was given the alternative name “Kama Pond,” and it became the origin of the district name “Kamashimizu.”
The water temperature remains nearly constant throughout the year, maintaining clear, limpid water quality. The local residents have a history of using this water as domestic water from ancient times, and even today, many people visit in search of this famous water.
The Legend of Kobo Daishi Kukai: Gratitude to an Old Woman and the Miracle of the Pilgrim’s Staff
The most famous legend associated with Kobo Pond is the story of Kobo Daishi Kukai and a kind old woman. This legend is passed down as a particularly moving episode among the many Kobo Daishi traditions found throughout Ishikawa Prefecture.
Details of the Legend
In the early Heian period, Kobo Daishi Kukai, who was traveling throughout the country, visited this area and encountered an old woman. At that time, this region was lacking in water, and residents were forced to endure the hardship of traveling far to draw water.
Suffering from thirst during his journey, Kukai received precious water from the old woman without hesitation, and she offered him wholehearted hospitality. Deeply grateful for the old woman’s kindness, Kukai thought of wanting to give her something in return.
Kukai forcefully thrust the pilgrim’s staff (shakujo) he held in his hand into the rock. Then, from that spot, clear water sprang forth, becoming a spring that would never run dry. This freed the villagers from the suffering of water shortage.
Significance of the Legend
This legend is not merely a tale of miracles but contains deep teachings about compassion in Buddhism, the importance of gratitude, and salvation for people in difficult circumstances. Kobo Daishi Kukai is known as the founder of the Shingon sect, but he left similar “legends involving water” in various places throughout the country, each becoming a subject of faith in their respective regions.
Numerous temples and shrines connected to Kobo Daishi Kukai exist throughout Ishikawa Prefecture, and Kobo Daishi faith remains deeply rooted from the Noto region to the Kaga region. Kobo Pond can be said to be a precious place where the legend remains in a particularly concrete form among these sites.
Nationally Rare Pothole Spring Water: Geological Significance
The greatest feature of Kobo Pond is the geologically extremely rare phenomenon of spring water being produced from a pothole (ouketsu). This characteristic is explained in detail below.
What is a Pothole?
A pothole is a circular or elliptical hole created when stones and sand carried by river rapids rotate in a whirlpool-like motion within a depression in bedrock, gradually carving away the rock over a long period of time. In English, it is called a “pothole,” which literally describes its “pot-like” shape.
Normally, potholes are found at the bottom of rivers or in places that were once rivers where water currently flows. However, cases like Kobo Pond where groundwater springs forth from a pothole are extremely rare nationwide.
The Geological Formation Process of Kobo Pond
The area around Kamashimizu Town in Nomi City, where Kobo Pond is located, is thought to have been the former course of the Tedori River. The Tedori River is the largest river in Ishikawa Prefecture, originating from Mount Hakusan and flowing into the Japan Sea as a rapid river.
Tens of thousands of years ago, the fierce flow of the ancient Tedori River that flowed through this region carved away bedrock to form potholes. Subsequently, the river’s course changed, and this location was no longer a river bottom. However, it is believed that through a fortunate coincidence, a groundwater vein happened to spring forth at the surface exactly at the location of the pothole, forming the present-day Kobo Pond.
Characteristics of Water Quality
The water of Kobo Pond, being groundwater flowing from deep underground, maintains a nearly constant temperature throughout the year (approximately 13-15 degrees Celsius). Additionally, as it is naturally filtered through geological strata, it is very clear and transparent with high clarity and contains mineral components in good balance.
This water quality was evaluated highly, and it was selected as one of the “Hundred Best Waters of the Showa Era” chosen by the Ministry of the Environment. Historically, local people have used it as drinking water and domestic water from ancient times, and even today, people continue to visit to draw water.
The Hundred Best Waters of the Showa Era: Evaluation of Kobo Pond’s Water
The water of Kobo Pond was selected as one of the “Hundred Best Waters of the Showa Era” chosen by the Ministry of the Environment in 1985 (Showa 60). This selection aims to preserve excellent spring water and river water throughout the country and make their value widely known.
Selection Criteria for the Hundred Best Waters
To be selected as one of the Hundred Best Waters, the following criteria are considered:
- Water Quality Excellence: The water should be clear and suitable for drinking
- Abundant Water Volume: Stable water quantity should be ensured
- Public Accessibility: The environment should be accessible and familiar to residents and visitors
- Conservation Activities: Conservation activities should be conducted by the local community
- History and Culture: Strong connections to the region’s history and culture
Kobo Pond met all these criteria, and it was highly evaluated particularly for its historical and cultural background through the Kobo Daishi legend and its geological value as spring water from a pothole.

The Relationship Between Kobo Daishi Kukai and the Hokuriku Region
To deeply understand the legend of Kobo Pond, it is important to understand the relationship between Kobo Daishi Kukai and the Hokuriku region.
The Life of Kobo Daishi Kukai
Kobo Daishi Kukai (774-835) was a Buddhist monk in the early Heian period and is known as the founder of the Shingon sect. Born in Sanuki Province (present-day Kagawa Prefecture), he studied Buddhism from a young age and departed for China in 804 as part of an official mission to Tang Dynasty China.
In China, he studied the mysteries of esoteric Buddhism from Keika Acharya and returned to Japan in just two years. After his return, he established Kongobuji Temple on Mount Koya, making it the center of Shingon esotericism. He also received Toji Temple in Kyoto and devoted himself to spreading esoteric Buddhism.
Kukai was not only exceptional as a religious figure but also demonstrated outstanding talents as an educator, calligrapher, and civil engineer, having significant influence on Japanese culture.
Kobo Daishi’s Nationwide Pilgrimage Legends
Legends of Kobo Daishi traveling throughout the country and saving people exist in many places. Particularly, legends involving “water” are found all over the country, with the following patterns observed:

- He dug wells for villages suffering from drought
- He changed poisoned water into pure water
- He discovered hot springs
While it is often uncertain whether Kobo Daishi actually visited these locations, these legends are thought to have been born from the deep faith of the common people in Kobo Daishi combined with the important life issue of securing water.
