Aoike Pond (Mishaka-ike) is a breathtaking scenic pond located within the Yatsugatake Chushin Kogen Quasi-National Park in Chino City, Nagano Prefecture, at an altitude of approximately 1,500 meters. It is widely renowned as the inspiration for the masterpiece 'Green Echoes' (Midori Hibiku) by the legendary Japanese painter Kaii Higashiyama. When the water is still, it acts as a perfect mirror, reflecting the surrounding mountains and trees with such clarity that it evokes a deep sense of awe in all who visit. The pond covers an area of about 0.1 hectares with a maximum depth of 8 meters, capturing the essence of Japanese natural serenity.
The pond was originally completed in 1933 as an agricultural reservoir. Historically, the region faced challenges in agriculture due to the cold water, but through the management of spring water, the environment was optimized for rice cultivation. The name 'Mishaka' is believed to be derived from the 'Mishayama Mikari Shinji' ritual of the Suwa Grand Shrine, suggesting that this land has long been regarded as a sacred and spiritual site. Today, it is a cherished cultural and natural spot loved by tourists and photography enthusiasts alike.

The greatest charm of Aoike Pond is the 'mirror reflection' seen on calm days. The sight of the larch forests and mountains reflected on the flawless, still surface is nothing short of a work of art. Visitors can also observe various flora such as bellflowers and lilies, as well as wildlife including ducks, damselflies, and butterflies. The unique ecosystem, including the mosses on the pond bed, adds to the natural beauty of this location.
The expression of the pond changes dramatically depending on the season and time of day. In spring, you can enjoy the vibrant fresh greenery; in summer, the deep, quiet forest tones; in autumn, the brilliant golden hues of the changing leaves; and in winter, a serene silver world covered in snow and ice. Because the light angle changes the reflection and color intensity, visiting in the clear morning air or during the soft light of the afternoon provides different, equally beautiful experiences.

The primary activity here is quiet observation and photography. Immersing yourself in the world of Kaii Higashiyama's art while facing nature in silence offers a special escape from daily life. There are well-maintained paths (with railings) that allow you to enjoy the view safely and closely while listening to the subtle sounds of the forest.
Aoike Pond is situated near the Okutadeshiraka Onsen area and Tateshina Highland, both rich in natural beauty. The surrounding area features various hiking trails and spots steeped in local history. There are many nearby accommodations where you can stay to fully enjoy the mountain environment.
