Chūbu-Sangaku National Park (中部山岳国立公園 Chūbu Sangaku Kokuritsu Kōen) is a national park in the Chūbu region, Honshū, Japan. It was established around the Hida Mountains and encompasses parts of Nagano, Gifu, Toyama and Niigata prefectures. It was designated a national park on December 4, 1934, along with Daisetsuzan National Park, Akan National Park, Nikkō National Park, and Aso Kujū National Park.
The Hida Mountains, or Northern Alps make up the majority of the park. There are many points in the Hida Mountains within the park that are above 3,000 m (9,843 ft), including Kamikōchi, the Norikura Plateau, Mount Hotaka and Mount Tate. The park is home to numerous gorges, ravines, and dramatically shaped escarpments.
The Chūbu-Sangaku National Park has become the most important hiking area in Japan.
