[1] The Shimogō site is located in the central part of alluvial lowland of the lower Yasu River.

In addition to Yayoi earthenware, a large number of wooden artifacts, woven baskets and stone tools have been excavated from the site.

Since the site has a high groundwater level, much organic material, including plant seeds and animal bones have been preserved.

In the surroundings of this bridge, many fragments of bronze swords, ground stone tools, broken bows, wooden shields, and arrow or spearheads have been excavated, suggesting that there was once a large-scale armed conflict at the entrance of the village.

[2] The site is approximately 24 minutes on foot from the JR West Biwako Line Moriyama Station and is now an archaeological park with a museum.
