The Izuruhara Benten Pond Spring Water (出流原弁天池湧水) located in Sano City, Tochigi Prefecture, is a famous water spot also called the “Kanto Region’s Monet’s Pond” due to its remarkable transparency and beauty. This spring-fed pond, selected as one of Japan’s 100 Best Waters by the Ministry of the Environment and protected as a Tochigi Prefecture Designated Natural Monument, has become Sano City’s signature tourist destination visited by many tourists throughout the year.
This article comprehensively explains everything you should know before visiting the site, from the characteristics and history of Izuruhara Benten Pond Spring Water to access methods and surrounding tourist information.
What is Izuruhara Benten Pond Spring Water?
Izuruhara Benten Pond Spring Water is a spring-fed pond located within Isoyama Park in Izuruharamachi, Sano City, Tochigi Prefecture. The pond, with a perimeter of approximately 138 meters, is filled with clear water that springs forth from caverns formed by the dissolution of limestone from the Paleozoic layer.
Selection as One of Japan’s 100 Best Waters
In 1985 (Showa 60), it was selected as one of Japan’s 100 Best Waters by the Ministry of the Environment. This designation indicates that the water quality is excellent and that it deserves preservation as a valuable water resource for the region. Furthermore, the pond itself was designated as a Tochigi Prefecture Designated Natural Monument in 1956 (Showa 31), and its value as a natural heritage is highly appreciated.
Water Quality Characteristics of Izuruhara Benten Pond
The greatest feature of Izuruhara Benten Pond Spring Water lies in its stable water quality. Throughout the year, the spring water volume remains constant at approximately 2,400 cubic meters per day, and the water temperature is stable at approximately 16 degrees Celsius regardless of the season. This constant water temperature and abundant spring water volume keep the pond’s water perpetually clear.
The transparency of the water is extremely high, and when standing at the pond’s edge and looking down, you can see clearly all the way to the bottom. The carp swimming in the pond appear to be floating in mid-air, and you can observe their scales’ brilliance and the green plants swaying at the bottom with remarkable clarity.
Geological Background of Izuruhara Benten Pond
The secret to the beauty of Izuruhara Benten Pond Spring Water lies in its geological structure. The area is formed of limestone from the Chichibu Paleozoic layer, and over long periods of time, groundwater dissolved the limestone to form stalactite caves. Water springng from these caves becomes extremely clear water after passing through nature’s filtration process and fills the pond.
As the water passes through the limestone layer, it not only has impurities removed but becomes high-quality water with an appropriate amount of minerals. This geological mechanism is a factor that produces the superior water quality of Izuruhara Benten Pond Spring Water.
As the Source of the Izuru River
Izuruhara Benten Pond Spring Water is also the source of the Izuru River. The clear water overflowing from the pond becomes the Izuru River and flows, playing an important role as a water resource for the surrounding area. It is also the source of the Akami Hot Spring and has multifaceted value as a regional tourist resource.
The Izuru River flows through Sano City and has a history of being used as agricultural and domestic water for the region, making it a water system closely connected to residents’ lives.
Isoyama Benzaiten and Izuruhara Benten Pond
Izuruhara Benten Pond is located within the precincts of Isoyama Benzaiten (Isoyama Park). Isoyama Benzaiten is a sacred site that has attracted faith since ancient times and is known as a Shinto shrine dedicated to Benzaiten.
Benzaiten is revered as the god of water, and it is natural that she is enshrined in this place where clear spring water springs forth. Visitors can view the beauty of Benten Pond while making peaceful prayers.
Within the precincts, there is also a place dedicated to the white snake, which is believed to be Benzaiten’s messenger. The clear spring water combined with the sacred atmosphere has become popular as a spiritual power spot.
Beauty Through the Four Seasons
Izuruhara Benten Pond Spring Water displays a different appearance throughout the four seasons.
Izuruhara Benten Pond in Spring
In spring, the surrounding trees are enveloped in fresh green, and vibrant greenery is reflected on the water’s surface. During cherry blossom season, sakura trees blooming around the pond scatter petals onto the water’s surface, creating a fantastical landscape.
Izuruhara Benten Pond in Summer
In summer, trees covered in deep green reflect on the water’s surface, creating a profound emerald-colored landscape. Since the water temperature is as low as 16 degrees Celsius, a cool atmosphere lingers even in summer, making it popular as a summer retreat.
Izuruhara Benten Pond in Autumn
In autumn, autumn leaves color the pond. The sight of red and yellow leaves reflected on the transparent water surface is truly worthy of being called the “Kanto Region’s Monet’s Pond” with its picturesque beauty. The autumn foliage season is especially popular and attracts many tourists.
Izuruhara Benten Pond in Winter
In winter, the surrounding trees lose their leaves, and the pond’s water transparency becomes even more prominent. Because the air is clear, the bottom of the pond becomes more visible. On snowy days, the contrast between the silvery white world and the transparent pond creates a beautiful landscape.
