Yamanouchi, located in the Japanese Alps, includes Shiga Highlands, one of the largest ski resorts in Japan. The town of Yamanouchi hosted three venues during the 1998 Winter Olympics: Snowboarding Half-pipe events were held at Kanbayashi Snowboard Park and the technical events of Alpine skiing were held at Mount Higashidate and Mount Yakebitai. The town of Yamanouchi is a gateway to Jōshin'etsu-kōgen National Park via Route 292, the Shiga-Kusatsu-Kogen Highway. This route is a mountain-ridge which connects Yamanouchi to Karuizawa in the south.

Yamanouchi is also home to Jigokudani Monkey Park where Japanese macaques can be found soaking in an outdoor hot spring. These macaques were part of the opening sequence in Baraka, the 1992 non-narrative documentary film directed by Ron Fricke.

Geography

Shimotakai District, in northern mountainous Nagano Prefecture, comprises Yamanouchi town, Kijimadaira Village, and Nozawaonsen Village. Yamanouchi is the largest of these. More than 90% of Yamanouchi is covered by mountains and forests. The town measures approximately 39 kilometers east-west and 12 kilometers north-south (266 square kilometers), and has an elevation ranging from 424 meters to 2341 meters. The surrounding area is known for its forest therapy.

In winter, damp air from the Japan Sea hits the mountains causing heavy snowing. Many ski resorts operate in the area. The plateau above the town is dotted with over 70 large and small wetlands and ponds which can be traced to volcanic activity. The main mountains include Mt. Yokote, Mt. Uriwa, Mt. Iwasugeyama, Mt. Shiga, and Mt. Kousha.
