Jigokudani Yaen Koen in Yamanouchi is a gorge-side park in northern Nagano Prefecture, set around the Yokoyu River valley at about 850 metres above sea level. Its most recognisable scene is the mix of hot spring water, rock walls and Japanese macaques in one confined landscape.

The park sits in the Valley of Yokoyu River, within Joshinetsu-Kogen National Park, and the official name appears in Japanese as ???????. The site is in Yamanouchi Town, a mountain area long associated with Jigokudani Onsen and the surrounding ski country.altitude 850 metres
The physical setting matters as much as the animals. Steep rock, flowing water and a narrow gorge give the place a compressed, enclosed look, while the park itself keeps the macaques at the centre of the visitor experience.steep rocky gorge
1964 and the public life of wild macaques
The park opened in 1964 and is closely linked with Hara Sogo, the first director named in accounts of its early years. That date places the site in Japan’s post-war tourism landscape, when wildlife viewing and mountain travel were being reshaped for a wider public.opened in 1964
The park’s identity rests on Japanese macaques, not on buildings or formal gardens. Snow, hot spring water and the animals’ presence create the image most people associate with Jigokudani Yaen Koen, while the site remains a place for observing wildlife in a managed landscape.Japanese macaques
The hot spring landscape and the monkeys
Natural hot springs rise in the Jigokudani area, and the park’s reputation comes from macaques gathering around that water in a setting shaped by rock, steam and winter snow. The park is known in English as the Snow Monkey Park as well as Jigokudani Yaen Koen.natural hot springs
The park’s appeal lies in that direct combination of landscape and animal life. It is a place where the gorge itself becomes part of the setting, with the river valley, the springs and the macaques forming one continuous scene.Valley of Yokoyu River
Visiting Jigokudani Yaen Koen: what travellers from Western Europe should know
