Basic Information about Shirakami Sanchi and Aoike
Shirakami Sanchi as a World Heritage Site
Shirakami Sanchi was inscribed as a UNESCO World Heritage Site in 1993. Spanning Aomori and Akita Prefectures, it is home to the largest primeval beech forest in the world. Because the forest has never been subjected to large-scale logging, it preserves an invaluable natural ecosystem. Rare species such as the black woodpecker and golden eagle inhabit the area, and the region continues to be the focus of ecological research and conservation efforts. Within this vast mountain range lies the Jūniko cluster of 33 lakes, the most famous of which is Aoike.
