The museum is positioned on the Utsukushigahara Plateau, one of the largest flat-topped mountains in Japan.
It is affiliated with the Fujisankei Communications Group, which also operates the Hakone Open-Air Museum.
The high altitude often causes the site to be enveloped in dense fog, creating a distinct, shifting atmosphere for the sculptures.
Several sculptures are designed to be interactive, allowing visitors to climb or walk through them.
The museum complex includes an indoor art gallery known as the 'Gallery of Art' for sensitive or smaller-scale works.
Utsukushigahara Open Air Museum is a satellite of the Hakone Open-Air Museum located at an elevation of approximately 2,000 meters in the Utsukushigahara Highlands. The museum features over 350 permanent contemporary sculptures displayed across a vast, rolling mountainous landscape. It covers a sprawling site that integrates art installations with the natural topography of the Nagano peaks. The collection includes works by internationally recognized artists such as Alexander Calder and Niki de Saint Phalle. Because of its high-altitude location, the site offers panoramic views of the Northern and Southern Japanese Alps and Mount Fuji. The grounds are expansive, requiring significant walking across hilly, grassy terrain.
