Overview of the Shirakami Mountains and Sobari Lake
Shirakami Mountains: A UNESCO World Natural Heritage Site
The Shirakami Mountains are a vast mountainous region spanning approximately 130,000 hectares across northwestern Akita Prefecture and southwestern Aomori Prefecture. Of this area, 16,971 hectares in the central region were registered as Japan’s first UNESCO World Natural Heritage site in December 1993, along with Yakushima Island.
The defining characteristic of the Shirakami Mountains is the distribution of East Asia’s largest primordial beech forest, which has been minimally affected by human activity. Diverse flora and fauna inhabit this area, maintaining a precious ecosystem. The World Heritage-designated area is divided into “core areas” and “buffer zones,” and while entry into the core area requires permission, hiking and trekking can be enjoyed in the buffer zones.
Characteristics and History of Sobari Lake
Sobari Lake is a reservoir dam created by damming the Kasugekedake River, located in Fujisato Town, Akita Prefecture. Its official name is “Sobari Dam,” completed in 1965. Built for flood control and hydroelectric power generation, the lake now serves as the primary access point to the Shirakami Mountains from the Akita side and is enjoyed by many as a recreational area for experiencing nature.
The surrounding area is developed as a national recreation area, with various facilities arranged throughout Sobari Park. The landscape of broadleaf trees and Akita cedar spreading through beautiful valleys provides seasonal natural beauty to visitors. Particularly during autumn foliage season, the vibrant autumn leaves reflected on the lake surface create a spectacular sight.
