The site is located on the southeastern edge of the Hekikai Plateau on the right bank of the Yahagi River. The ruins date from the 7th century and are believed to be the oldest temple ruins in Aichi Prefecture, although the name of the temple does not appear in any known historical records. The precincts cover an area of 126.5 meters from east-to-west and 140 meters from north-to-south.
