People can be seen collecting wild vegetables in the surrounding area (prior confirmation is necessary if permits are required). Spring flowers also begin blooming, making it an ideal season for nature walks.
Summer (June to August)
The spring water location in summer functions as a natural cooler. The area around the flowing cold spring water has a temperature several degrees lower than surroundings, attracting those seeking coolness.
Early morning or evening visits are recommended. Daytime temperatures become high, so do not forget adequate hydration and heatstroke prevention measures. Insect repellent is essential.

Scientific Aspects of Spring Water
Spring Water Mechanism
Spring water is a phenomenon where groundwater naturally flows out to the surface. Ginmizu-sawa Spring Water is also formed by this mechanism.
Conditions for Spring Water Formation:
- Abundant Precipitation: Rainwater or snowmelt infiltrates underground
- Highly Permeable Geological Layers: Geology structure that allows water to pass through easily
- Existence of Impermeable Layers: Layers that stop water, allowing water accumulation
- Topographic Conditions: Terrain where groundwater is pushed to the surface
Relationship with Geology
The geology of Ibaraki Prefecture is endowed with conditions suitable for spring water formation. The alternation of highly permeable layers such as volcanic ash soil and gravel layers with impermeable layers such as clay allows groundwater to be efficiently stored and appear at the surface as spring water.
Ginmizu-sawa Spring Water is thought to be located in a place blessed with such geological conditions. During passage through geological layers, water is naturally filtered and becomes clean with mineral components.
Water Quality Formation Process
Spring water quality is determined during underground flow:
- Precipitation: Rain or snow falls to the earth’s surface
- Infiltration: Water seeps underground through soil and bedrock crevices
- Filtration: Soil and geological layers function as natural filters
- Mineral Dissolution: Mineral components dissolve from rocks and minerals
- Storage: Groundwater accumulates above the impermeable layer
- Discharge: Appears at the surface due to topographic conditions
This process can take years to decades, or in some cases, hundreds of years.
