Shingū ruins

The site is located on a river terrace of the Yahagi River near its conjunction with the Oto River. The ruins cover a wide area of 40,000 square meters and has only been partially excavated. Thus far, the foundations for 12 pit dwellings from the Jōmon period, 37 clay-jar burials, six dirt burials and one square-sided tumulus from the Yayoi period, 11 pit dwellings from the Kofun period, 6 pit dwellings from the Nara period, 19 pit dwellings and one raised floor building form the Heian period have been discovered. Finds included a large amount of artifacts, with including earthenware and stoneware shards, ceremonial stone swords, and clay figurines from the Yayoi period. Sue ware and pottery from the Kofun and Heian periods were also found. The ruins are valuable in that they present a record of continuous occupation from the Jōmon through Kamakura periods.

The site was discovered in 1973. Excavations were carried out more than a dozen times from 1974 when the site was endangered by a nearby housing development. It is currently back-filled by one meter of earth to protect the ruins, but an archaeological park has been established with six reproductions of residences from the late Jōmon period, 30 earthenware tombs from the Yayoi period and one square tomb from the Kofun period. In the past, most of the excavated items were displayed at the Okazaki City Folk Museum, but are now stored at the Okazaki City Museum of Art.

The park is located five minutes on foot from Higashi-Okazaki Station on the Meitetsu Nagoya Main Line .
