The park contains over 25 individual dinosaur sculptures, most of which are cast in concrete.
The sculptures are integrated into a sloped hillside, requiring visitors to walk a significant incline to see the full collection.
The park is situated within a larger municipal recreation zone that also includes the Chausuyama Zoo.
Many of the dinosaur models were designed to be interactive, allowing children to climb on or crawl through portions of the sculptures.
The site uses its natural mountain elevation to provide elevated views of the Nagano basin.
Chausuyama Dinosaur Park is an expansive outdoor recreation area featuring over 25 life-sized, concrete-sculpted dinosaur models embedded directly into a sloped forest landscape. The park is integrated into the larger Chausuyama Zoo complex and offers visitors a hiking-style experience through various prehistoric-themed zones. It is designed to simulate a primeval environment, with sculptures ranging from small reptiles to massive sauropods. The layout utilizes the natural terrain of the mountainside to create immersive sightlines between the sculptures and the surrounding trees. It serves as a family-oriented destination that combines physical exercise with educational displays about paleontology. The park emphasizes outdoor movement, requiring guests to navigate paths connecting the various dinosaur displays.
