Mizunashi Former Fish Farm Spring Water (Tochigi Prefecture) Complete Guide | Hidden Famous Water Spot in Nikko and the Charm of Mizunashi Spring Water Hermitage
In the Mizunashi district of Nikko City, Tochigi Prefecture, there is beautiful spring water that was once used as a fish farm. This location, where underground water flows from the Nikko mountain range, is a famous water spot selected for the “Nikko Landscape with Water: 100 Selections,” while maintaining a quiet charm untouched by tourism. This article provides detailed information about the history and characteristics of the Mizunashi Former Fish Farm Spring Water, as well as the popular soba restaurant “Mizunashi Spring Water Hermitage” that utilizes this spring water.
What is Mizunashi Former Fish Farm Spring Water?
Geographic Features of Mizunashi District
The Mizunashi district is located in the Imaichi area of Nikko City, spreading across paddy fields at the foot of the Nikko mountain range. This region has long been blessed with abundant spring water and is known as the “Village of Famous Water.” Rain and snow that fall on the Nikko mountains infiltrate underground, and after being filtered over many years, the water emerges here as clear spring water at the surface.
The place name “Mizunashi” is said to derive either from the fact that water was once so abundant that water channel management was unnecessary, or from “water that never runs out” due to numerous spring water points in the area. In fact, multiple spring water locations exist in this region and have been used for generations as household water and agricultural water for local residents.
History as a Fish Farm
The Mizunashi fish farm was a facility established to utilize these abundant spring waters. The spring water maintains stable temperatures throughout the year, being cold in summer and relatively warm in winter—characteristics ideal for fish farming. This property was particularly suitable for raising freshwater fish such as carp and rainbow trout.
During the time the fish farm was in operation, elegant carp could be seen swimming in pools of clear spring water, making it a notable local attraction. Even now, carp swim in the spring water pool as a remnant of those days, delighting visitors. While commercial fish farming operations have ended, the spring water itself continues to flow abundantly as ever.
Characteristics and Water Quality of Mizunashi Spring Water
Water Volume and Temperature
The Mizunashi former fish farm spring water produces a considerable amount of water daily. While precise official data on water volume is limited, visitors to the site can confirm that water continuously flows from the spring water pool. This abundant water volume results from the Nikko mountain range’s vast water collection area and the excellent water permeability of its volcanic geology.
The water temperature remains stable at approximately 12–15 degrees Celsius year-round, offering a refreshing coolness even in summer. In winter, the water rarely freezes, and this stable temperature provides ideal conditions for fish habitat and water used in soba making.
Water Quality Characteristics
The Mizunashi spring water undergoes natural filtration as it passes through the Nikko mountain range’s volcanic rock layers over extended periods. Consequently, it boasts extremely high transparency, with the pool bottom clearly visible as if through glass.
The mineral content is well-balanced, and the hardness is classified as relatively soft water. This soft water property brings out the taste of ingredients when used in soba making or cooking. Additionally, with low iron and sulfur content, it is valued as water that is easy to drink without any unpleasant aftertaste.
Environmental Conservation Efforts
In the Mizunashi district, efforts to conserve the environment around spring water are conducted primarily by local residents and staff at “Mizunashi Spring Water Hermitage.” Through cleaning around the spring water pool, vegetation management, and water quality monitoring, ongoing efforts ensure this precious natural resource is passed on to future generations.
Nikko City has selected the Mizunashi spring water as one of the “Nikko Landscape with Water: 100 Selections,” working to raise citizens’ environmental awareness and utilize it as a tourism resource. However, excessive tourism development is avoided in favor of maintaining a quiet environment, preserving the intrinsic value of the spring water.
