Preservation of the Ruins
To preserve these important ruins, the surface of actual structural remains is covered with two layers; over 30 cm mounds for protection and earth fill for park embankment. The Yayoi village has been reborn atop the original ruins without damaging the valuable ruins.
Yoshinogari Historical Park is for the preservation and use of the Yoshinogari ruins, a national special historic site symbolizing our nations culture. Research was conducted not only in the field of archeology but in every kind of related scholarship for authentic reconstruction.
First, it was debated on what the period and village, when the village existed, looked like in Japanese history. Next, value of existence, reason and purpose of every building was considered. Lastly, the shapes and structures of each building were studied. To reconstruct Yoshinogari, research in every field was conducted.
