It was named as Konpira-yama Mountain Tumulus since Konpira-jinja Shrine, known as the guardian of sailing, was enshrined on top of the tumulus body; it is an interesting point to note that the enshrined guardian deity is the same Omono nushinokami with Miwa-yama Mountain Omiwa-jinja Shrine.
コンピラ山古墳は、航海守護として知られる金毘羅神社が墳丘上に祀ってあったことから名がついたもので、三輪山大神神社の大物主神と祭神が同じであるのは興味深い。
