The pond is colloquially nicknamed 'Swan Lake' due to the migratory birds that frequent the water.
The water is supplied entirely by underground springs, ensuring it remains clear throughout the year.
The surrounding trees are primarily Japanese larch, which turn a distinct golden yellow in late autumn.
The pond was originally part of a private estate before becoming a publicly accessible scenic site.
Kumoba Pond, locally known as Swan Lake, is a spring-fed body of water located in the Karuizawa resort town. The pond is characterized by its perimeter walking trail that circles the entire water feature through a dense forest of larch and maple trees. It is highly regarded for its reflection of seasonal foliage, particularly during the autumn peak in late October. The site is a natural habitat for various migratory birds, including mallards and occasionally swans. The landscape is designed to emphasize the contrast between the dark water and the surrounding seasonal vegetation. The walking circuit is flat and well-maintained, making it accessible for most visitors. It remains one of the most photographed locations in Nagano Prefecture due to the clarity of the water and the symmetrical tree lines.
The wooden bridge located at the northern end of the pond provides the most iconic view of the water reflecting the forest.
Bring a polarizing filter for your camera to reduce glare on the water and enhance the reflection of the trees.
Complete the full 250-meter walking loop to see the pond from multiple elevations and lighting angles.
Carry mosquito repellent if visiting during the humid summer months.
Do not feed the ducks or other birds as it disrupts the local ecosystem and feeding patterns.
Stay on the designated gravel path to protect the shoreline vegetation and keep noise levels low to avoid disturbing local wildlife.
