The shell mound is a place where Jomon people eat and throw away shells, and you can find earthenware and human bones, and you can see how they lived at that time. Yoshigo Shell Mound (Yoshigo Town) is a representative shell mound of the Jomon period in Japan. During the Taisho era, a survey by a doctor at Kyoto University discovered more than 300 human bones, which became a hot topic. In 1951, the first excavation survey in Japan was conducted based on the Law for the Protection of Cultural Properties, and many earthenware, stone tools, Jomon human bones, etc. were excavated, and in December of the same year, it was designated as a national historic site.
Yoshigo Shell Mound became a historic park in 2007, and the museum was opened. The life at that time is explained in an easy-to-understand manner with models, photographs, and excavated items.
