Sori Falls is a striking vertical waterfall located on the Nakazawa River, which originates from the Yakeyama mountain range (elevation 1,366m) in southern Kazuno City, Akita Prefecture. The most defining feature is its 25-meter drop, where the river plunges vertically down an overhanging cliff. This creates a unique and powerful visual of water falling straight down, a sight that can only be experienced here. The surrounding mountains provide a majestic backdrop, emphasizing the sharp, vertical lines of the falling water.
The area lies at the foot of the Yakeyama mountains, part of the Hachimantai mountain system, a region blessed with abundant water resources and a rich natural environment since ancient times. While there are no specific historical buildings or legends tied directly to the falls, Sori Falls stands as a testament to the raw, sculptural beauty of nature. It is recognized in Japanese topographical guides as a site with a particularly distinctive and impressive geological formation.

The primary attraction is the sheer force of the 25-meter vertical waterfall. Because the water falls from an overhanging cliff, the trajectory of the water is incredibly dynamic and dramatic. Observing the water strike the base of the cliff provides a sense of awe. The harmony between the vertical water flow and the surrounding mountain landscape makes this an exceptional spot for photography and nature study.
You can enjoy different charms depending on the season. The contrast between the white falling water and the surrounding greenery is particularly striking during the lush summer months. However, the scenery is also beautiful as the seasons change. Please note that water volume increases significantly after heavy rainfall. For the best viewing experience, we recommend visiting during bright daylight hours, which allows you to clearly observe the texture of the cliff and the movement of the water.
The visit primarily involves a nature walk to the base of the falls. Located near National Route 341, the trek to the waterfall basin takes approximately 15 minutes. While you do not need professional mountaineering gear, the path is a natural trail, so prepare for a walk through a natural environment. It is a wonderful way to experience the raw power of the Nakazawa River up close.
