The Yoshinogari Ruins were discovered in 1989 and are the largest Yayoi period (3rd Century) ruins in Japan. The ruins cover an area of roughly 40 hectares spreading throughout the towns of Kanzaki and Yoshinogari. The discovery of the ruins casts doubts on the theory that there were no large scale moated settlements in Kyushu. Many artifacts have been excavated. By discovering the enormous burial mounds thought to belong to royalty, visitors to the park will be able to understand the changes that occurred during the 600 years of the Yayoi period as well as getting to know the whole story behind this settlement focusing on this “country” in the Yayoi period. Along with the on-going excavations within Yoshinogari History Park, restorations of the “latter half of the Yayoi period” are continuing. The Yoshinogari History Park is a park allowing its visitors to feel the romanticism of ancient Yayoi.
