| There is a height difference in several meters between the exterior embankment of Tsukiyama Tumulus and Konpira-yama Mountain Tumulus, which extends out and encircle Tsukiyama Tumulus, and forms a pond at one location called Tsuga Pond. |
また、築山古墳の周堤帯とコンピラ山古墳の間に数ｍの段差があり、それが、南に築山古墳を囲む形で延びており、一部は栂池という名の池となっている。 |
