This article comprehensively introduces information you should know before visiting this beautiful spring-fed pond, covering the charm, history, access methods, best timing for visits, and nearby tourist attractions of Nishi-Benten Pond (Izuruhara Benten Pond).
About Nishi-Benten Pond (Izuruhara Benten Pond)
Nishi-Benten Pond is a spring-fed pond located in Izuruhara-cho, Sano City, Tochigi Prefecture (in the Akemi Onsen area). Located within Isoyama Park, it is formed by abundant clear water gushing from cracks in limestone geological strata. This pond is also the source of the Izuru River, and together with the surrounding natural environment creates a beautiful landscape.
The pond has an area of approximately 300 square meters, and while the maximum water depth is about 2 meters, relatively shallow, its high transparency fascinates all who visit. Aquatic plants and swimming fish are visible with crystal clarity, creating an illusion as if water doesn’t exist at all.
Reasons for Selection as One of Japan’s Top 100 Waters
The Izuruhara Benten Pond spring water was recognized as one of Japan’s “Top 100 Waters” selected by the Ministry of the Environment in 1985 (Showa 60). This selection reflected comprehensive evaluation of water quality, abundant water volume, surrounding environmental conservation status, and protective activities by local residents.
The pond’s water volume reaches approximately 2,400 tons per day, maintaining stable water flow throughout the year. The water temperature remains constant at approximately 16 degrees Celsius across all seasons, feeling cold in summer and relatively warm in winter. This stable water temperature and abundant spring water volume are key factors in maintaining the pond’s high transparency.
Value as a Tochigi Prefecture Designated Natural Monument
Nishi-Benten Pond was designated as a Tochigi Prefecture Natural Monument in 1956 (Showa 31). This designation protects not only the pond itself but also the entire surrounding natural environment.
Water gushing from ancient limestone layers is highly pure water, filtered underground over long periods. This geological characteristic and the unique ecosystem it creates enhance its value as a natural monument. Trees of considerable age surround the pond, displaying their appearance in different ways throughout the four seasons.
Reasons for Being Called “Kanto Region’s Monet’s Pond”
Nishi-Benten Pond came to be known as “Kanto Region’s Monet’s Pond” and “Tochigi’s Monet’s Pond” due to similarities with “Monet’s Pond” in Seki City, Gifu Prefecture. The beautiful water surface scenery reminiscent of French Impressionist painter Claude Monet’s work “Water Lilies” became a major topic of conversation on social media.
The Secret of Transparency
Nishi-Benten Pond’s remarkable transparency is created by several factors.
First, it is spring water naturally filtered by passing through limestone strata. Limestone functions as an excellent natural filter, removing impurities while delivering water to the surface.
Second, abundant spring water volume ensures fresh water is constantly supplied. The 2,400-ton daily water volume constantly replenishes the pond water, preventing stagnation.
Third, the surrounding forest environment contributes to water quality conservation. Trees prevent soil erosion, and fallen leaves and other organic matter are appropriately decomposed, preventing water quality deterioration.
Best Photographic Conditions
There are optimal shooting conditions for bringing out Nishi-Benten Pond’s beauty to the fullest. Photography enthusiasts recommend the following combined conditions.
Windless days: Without wind, the water surface becomes mirror-like and calm, perfectly reflecting surrounding scenery. Early morning particularly tends to have calm winds, ideal for shooting.
Clear skies after rain: Rain washes dust from the air, providing clear visibility. Post-rain water volume may also increase, further enhancing pond transparency.
Light angle: The time from late morning through noon is when sunlight appropriately strikes the pond, making underwater conditions clearly visible. Avoiding backlit positions is recommended.
Four Seasons’ Charm
Nishi-Benten Pond reveals completely different faces depending on the season visited. The unique charm of each season is introduced below.
Spring (March to May)
Spring at Nishi-Benten Pond is a season when you can feel the vitality of fresh greenery. Surrounding trees begin budding, and pale green colors reflect on the water surface. Alpine flowers begin blooming around the pond, announcing spring’s arrival.
With rising temperatures, tourists are not yet numerous, allowing leisurely enjoyment of the pond’s beauty. During cherry blossom season, visiting nearby cherry blossom spots together is also recommended.
Summer (June to August)
Summer is the season when Nishi-Benten Pond receives the most attention. Surrounding forest thickly covered in green reflects on the water surface, creating a deep jade-colored world. The cool atmosphere created by 16-degree Celsius spring water provides healing to summer visitors.
The pond area, surrounded by forest, has direct sunlight blocked, making the perceived temperature several degrees lower than urban areas. Summer is the perfect time to visit Tochigi’s spectacular scenery spots, attracting many tourists.
However, summer is also peak tourist season, causing congestion on weekends and holidays. Early morning or weekday visits are recommended.
Autumn (September to November)
Autumn at Nishi-Benten Pond brings the finest season enveloped in autumn foliage. Surrounding trees turn red and yellow, and the spectacle of these vivid colors reflecting on transparent water is truly spectacular.
Autumn foliage typically peaks from late October through mid-November. Many photography enthusiasts visit during this period to capture beautiful autumn scenery. During foliage season, you can enjoy a colorful “Monet’s Pond” differing from spring and summer.
With clear autumn air, transparency further increases, which is another attraction.
Winter (December to February)
Winter at Nishi-Benten Pond creates a mysterious atmosphere of silence. Surrounding trees shed their leaves, revealing the pond’s structure more clearly.
Since water temperature remains constant at 16 degrees Celsius year-round, the pond doesn’t completely freeze even in bitter cold. Occasionally, frost forms around the pond or thin ice develops, creating fantastical scenery.
Winter is a low-tourism season, making it a hidden gem where you can experience the pond’s beauty undisturbed.
