This museum, located on the grounds of a pleasant park, is dedicated to the history of Hamamatsu and the surrounding area. Exhibits include locally-found pre-historic fossils, ancient pottery, old maps, and farming and domestic implements up through the Edo era. Also on the grounds are some shell mounds, evidence of pre-historic human life in the area. A reconstruction of a Jomon village has been installed among the mounds, giving the visitor an idea of what life was like here three to four thousand years ago. The name of the park and also the neighborhood, Shijimizuka, means "shell mound".
