This facility serves as the hub for the Kitahiroshima Ecomuseum, which collects and provides information on the natural splendor, history, and industry of the city based on the concept of the entire city being a roofless museum. The center collects and preserves materials regarding natural, historical, and cultural heritages in the city, engages in research, and holds exhibitions, educational programs, lectures, and other events.

The permanent exhibition area has exhibits featuring natural history, including displays on the history of the earth and geological formations and fossils found in the city. Also displayed are materials about local history that introduce three forerunners associated with the city. Models of a mammoth and its child, created with the help of many local residents, are also on display. The special exhibition area hosts two or three exhibitions annually under various themes.
