The area protected under the National Historic Site designation is only the portion containing the Maeda clan graves, and covers and area of 86,294.35 square meters. Within the Nodayama cemetery are the graves of some 80 members of the Maeda clan, including daimyō, official wives, and various children. The graves are unusual in that they take the form of dome-shaped tumuli in three layers, with a grave marker in front of each tumulus, resembling ancient dome-shaped kofun. Most of the daimyō graves have a diameter of 16 meters, with the exception of the grave of Maeda Toshiie, which is the largest at 19-meters. The size of these graves is unparalleled by other daimyō graveyards. Surrounding the tombs of each daimyō and his family are many smaller tombs for important retainers of the clan, as well as numerous Edo-period tombs of important residents of Kanazawa.
