The museum exhibits fossils of the 'Chichibu Mastodon,' providing evidence of megafauna that once inhabited the Japanese archipelago.
The outdoor geological park contains massive stone samples that illustrate the crustal movements responsible for forming the Kanto region.
The Saitama Prefectural Museum of Nature is located in the Nagatoro area, focusing on the geological and biological history of Saitama Prefecture. The collection features a prominent exhibit of the Paleoparadoxia, an extinct marine mammal fossil discovered within the region. Visitors can explore displays of regional flora and fauna, alongside taxidermy specimens representing local wildlife. The museum highlights the Chichibu Basin's unique geological formation process and its transition from a marine environment to land. Outdoor exhibits include a geopark-themed garden showcasing various rock formations found throughout the prefecture. It serves as a regional research center for natural history studies.
