Joshinetsu Kogen National Park

Established in 1949, Joshinetsu Kogen National Park covers a broad expanse of volcanic plateau and rugged mountain terrain spanning the Nagano, Gunma, and Niigata prefectures of central Japan. The park is characterized by its dramatic volcanic landscapes, including active and dormant volcanoes such as Mount Asama and Mount Kusatsu-Shirane, and scenic highland areas like the Shiga-kogen Highlands. The diverse ecology ranges from alpine flora and fauna to forested valleys and wetlands, supporting species like Japanese macaques and ptarmigans. This park also features renowned hot spring resorts, particularly in the Kusatsu and Shibu Onsen areas, drawing visitors year-round for relaxation and therapeutic waters. Outdoor enthusiasts can explore numerous hiking trails that provide breathtaking views of volcanic craters, alpine marshes, and panoramic mountain vistas. In winter, sections of Joshinetsu Kogen become popular ski destinations with extensive ski resorts and off-piste terrain. The park offers a combination of natural beauty, outdoor adventure, and cultural interest through its historic onsen towns. Key landmarks include the volcanic landscapes of Mount Asama, Shiga-kogen highland meadows famed for wildflowers, and the Jigokudani Monkey Park where visitors observe wild snow monkeys bathing in hot springs. The park is accessible from several nearby towns and cities, making it an attractive option for both domestic and international visitors seeking a diverse experience of Japan’s mountainous environment.
