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.
