Guida
Atera Valley is a vital component of the 'Kiso Road' Japan Heritage site, located in Nojiri, Okuwa Village, Kiso District, Nagano Prefecture. The greatest allure of this location lies in its mesmerizing emerald green waters and exceptional clarity. The water is so transparent that the pebbles and rocks on the riverbed are clearly visible. Surrounding the stream is a lush forest of Kiso's five famous trees, including Hinoki cypress. The natural artistry created by the steep rock faces and the vibrant colors of the water offers a deeply moving experience to all who visit.
This region has long been blessed with abundant wood and water. The Atera River originates from Mount Sunagoya, and its 15-kilometer stretch of pristine water has shaped the natural landscape alongside the history of the Kiso Road. Local communities place great importance on preserving this beautiful water and the surrounding cypress forests. For instance, to protect the water quality, activities like barbecuing directly by the water are restricted, with designated campsites provided elsewhere, reflecting a high level of environmental consciousness and dedication to nature conservation.
There are numerous spots throughout Atera Valley where you can witness the sublime beauty of nature. The sight of the emerald green water spreading across the valley is a view unique to this area. Notable landmarks include 'Inugari no Fuchi' and 'Kippo no Taki' waterfall. Furthermore, in the upper reaches, there is a spring known as 'Bigan-sui' (Beautiful Face Water). According to legend, washing your face with this water will lead to beautiful, fair skin, offering a special and mystical experience for visitors. The harmony of steep cliffs, dense forests, and the clear stream makes it an ideal location for photography and nature observation.
Atera Valley reveals a different face with every season. In spring and summer, beautiful wildflowers bloom among the trees, allowing you to feel the changing seasons. Autumn is particularly spectacular, as the contrast between the evergreen cypress and the colorful deciduous trees creates a brilliant display against the emerald water. In winter, the valley transforms into a silent, snow-covered landscape. For the best experience, we recommend visiting during daylight hours when the sun reflects off the water, highlighting the transparency and the vivid emerald hues.
Here, you can experience the artistry of nature with all five senses. Walking along the stream or simply listening to the sounds of the forest provides a perfect moment to escape daily life. If you choose to walk with a local guide, you may gain a deeper understanding of the local nature, history, and the stories of the people who have protected this water and forest for generations. Please note that to protect the environment, certain activities like riverside barbecues are restricted; visitors are asked to respect the natural surroundings.
Atera Valley is located just past the Atera Bridge in Nojiri, Okuwa Village. The surrounding area continues the beautiful scenery of the Kiso Road, characterized by historical landscapes and a rich natural environment. The local community actively works to preserve this environment, allowing you to feel a culture that lives in harmony with nature.
As this is a natural scenic area, we highly recommend wearing comfortable walking shoes and appropriate outdoor clothing. Sturdy, non-slip shoes are especially recommended if you plan to walk near the water or rocky areas. To protect the environment, please strictly follow etiquette such as taking your trash home and avoiding any actions that could pollute the water. Please check local conditions for any specific rules regarding access and facilities.
