Iizuna Highlands, Tableland in Nagano, Nagano Prefecture, Japan

Iizuna Highlands is a plateau on the southeastern slope of Mount Iizuna in the Ii district of Nagano city, Nagano Prefecture, ranging from about 800 to 1200 meters in elevation. It is divided into areas including the ski resort zone, a sports zone with grounds and a bobsleigh and luge park, and the Oza Boshi Pond and camp area with the Oyachi wetland.

The area gained international attention in 1998 when nearby Iizuna Resort hosted freestyle skiing competitions for the Winter Olympics. This event brought worldwide recognition to the region and its winter sports facilities.

Iizuna Highlands formed part of the Shugendo ascetic route toward Mount Togakushi, and the Ichino-torii gate here was the first torii of Togakushi Shrine. Shukubo pilgrim lodgings once lined the surrounding area. The plateau's grasslands have long been maintained by controlled burning, grazing and hay cutting.

Access is via the Togakushi Bird Line or the Asakawa Loop Line, about 30 minutes from central Nagano; the city road to Oza Boshi Pond has sharp bends closed to large and heavy vehicles. The highland spans roughly 800 to 1,200 m, so carry layers for quick temperature swings. Radio relay stations for the power company and NTT stand on the higher ground.

The plateau's eastern side holds Reizenji Lake, where hot-spring facilities sit beside the water. The high ground also carries wireless relay stations for the power company and NTT, and the old Daniel Norman residence stands as a Western-style building among the grassland.
