The eastern settlement contains more than 250 pit-dwellings of various sizes and a number of graves. The central settlement has two stone circles, with diameters of 80 meters by 50 meters, surrounding grave pits, encircled by what appear to be post holes to create a colonnade and to support ritual buildings. The southern portion of this area is raised earthen work, within which a large amount of pottery, stone tools, and burnt bone and plant remnants. The number of structures is also estimated to be between 300 and 500. The area also contains at least 20 dome-shaped kofun burial tumuli, with diameters of 8-10 meters, most of which have the remnants of horseshoe-shaped moats. The western area is largely unexcavated, but appears to be a residential area with between 70-100 dwellings.
