This article comprehensively conveys the charm of this famous water, covering the characteristics of Naibetsu River Spring Water, water quality, historical background, experience methods at the Famous Water Interaction Park, and access information.
What is Naibetsu River Spring Water | Reasons for Selection as Famous Water
Naibetsu River Spring Water is a collective name for spring water groups that flow into the Naibetsu River (Naibetsu-gawa), a tributary of the Chitose River. Although the Naibetsu River is only about 2.5 km long, over 60 spring water locations have been confirmed in this short section, boasting a generous water volume of approximately 60,000 tons per day.
Background of Famous Water Selection
When the Ministry of the Environment (then the Environment Agency) selected excellent water environments nationwide as the “100 Famous Waters” in 1985, Naibetsu River Spring Water was recognized as a representative famous water of Hokkaido. The following points were evaluated as reasons for selection:
- Abundant Water Volume: Stable spring water volume of 60,000 tons per day
- Excellent Water Quality: Clear water quality from Shikotsu Lake groundwater
- Regional Water Source: Importance as the main water source for Chitose City’s tap water
- Historical Value: Relationship with the Usakumai Ruins Group
- Natural Environment: Natural filtration function by Shikotsu volcano ejecta
Shikotsu Lake Caldera and Spring Water Mechanism
The water source of Naibetsu River Spring Water comes from rain and snow that fell on the outer rim mountains of the Shikotsu Lake Caldera, which was formed by volcanic activity approximately 40,000 years ago. This water seeps into the ground and passes through layers of Shikotsu volcano ejecta, being naturally filtered in the process, and emerges at the surface in the Naibetsu River basin over a long period of time.
The volcanic geological structure functions as a natural filter, producing delicious water containing an appropriate amount of minerals. This geological characteristic is the reason why Chitose City’s tap water is nationally known as “delicious water.”
