However, there are many different places with the same name across Japan, for example Hachiman-yama mountain, Inari-yama mountain, Otsuka-yama mountain, Chausu-yama mountain, Kuruma-zuka tumulus, Funa-yama mountain and Miya-yama mountain, and these names exist in many places and sometimes there are exactly the same names in a county or within an area of an old province; therefore, to distinguish the difference in those cases, usually the name of the oaza or higher rank names (such as the prefecture name) will be added to the original names, for example Inbehachiman-yama mountain Kofun, Inari-yama mountain Kofun, the Eta Funa-yama mountain Kofun and Mozuotsuka-yama mountain Kofun.
しかし、単に八幡山、稲荷山、大塚山、茶臼山、車塚、船山、宮山などと称する地名は各地にいくらでもみられ、時には同郡、同国内に複数存在する場合もあるので、どこの八幡山かを区別するために、井辺八幡山古墳、埼玉稲荷山古墳、江田船山古墳、百舌鳥大塚山古墳などと大字またはそれより上位の地名を付して呼称するのが通例である。
