Jōshin'etsu-kōgen National Park

Jōshin'etsu-kōgen National Park (上信越高原国立公園) is a national park in the Chūbu region of the main island of Honshū, Japan formed around several active and dormant volcanoes. It spans the mountainous areas of Gunma, Nagano, and Niigata prefectures. The name refers to the two mountain ranges that make up the park. It was divided into two separate areas: the Southern Niigata/North Nagano Area and the East Nagano Area.

History
Jōshin'etsu-kōgen National Park was established in 1949 and significantly expanded in 1956 to include the Myōkō-Togakushi mountainous region. The latter was separated as Myōkō-Togakushi Renzan National Park on March 27, 2015 with 39.772 ha.

Etymology
The name of the park consists of two elements. The first, "Jōshin'etsu", is a kanji acronym consisting of three characters which represent the former names of provinces of the area: Kōzuke Province (上野国) in present-day Gunma Prefecture, Shinano Province (信濃国) in present-day Nagano Prefecture, and Echigo Province (越後国) in present-day Niigata Prefecture. The second, "kōgen", means tableland or plateau.

Southwest Mikuni Mountain Range Area
Southwest Mikuni Mountain Range Area (三国山脈南西部) includes Mount Tanigawa (1963 m) and two active volcanoes -- Mount Kusatsu-Shirane (2162 m) and Mount Asama (2542 m). Mount Asama is the most active volcano on Honshū.
