The pond's distinctive color is caused by iron-rich, acidic spring water flowing from the nearby Tateshina mountains.
The water is highly acidic with a pH level that makes it unsuitable for fish, resulting in its unusual clarity.
The pond served as the inspiration for the painting 'Green Echoes' by renowned artist Kaii Higashiyama.
Mishaka Pond was originally constructed as an irrigation reservoir for local agricultural fields.
The area surrounding the pond is part of the Yatsugatake-Chushin Kogen Quasi-National Park.
Mishaka Pond is an irrigation reservoir in the mountains of Chino, Nagano, recognized for its exceptionally clear, mirror-like water surface. The pond is famous for its vibrant green algae and the reflection of surrounding larch and fir trees. It gained widespread popularity after appearing in the works of Japanese painter Kaii Higashiyama, specifically his painting titled 'Green Echoes'. The pond's acidic water, derived from the nearby Oku-Tateshina hot springs, prevents fish from thriving but contributes to the unique clarity and color of the water. Boardwalks are provided around the perimeter to facilitate viewing while protecting the surrounding wetland ecosystem. It remains a popular spot for landscape photography due to the changing foliage colors across the seasons.
The main wooden viewing platform at the pond entrance provides the clearest view of the reflections.
Bring a polarizing filter if you are using a camera to effectively manage reflections on the water's surface.
Ensure you stay on the designated wooden boardwalks to avoid damaging the sensitive marshland environment.
Dress in layers as the mountain elevation results in temperatures significantly lower than in the town center.
Attempting to walk off the paths or down to the water's edge, which causes erosion to the protected pond banks.
Access may be restricted or difficult during heavy winter snowfall; check local mountain road conditions before visiting.
Stay on the designated observation walkways; do not enter the water or touch the pond banks.
