The temple where Konpira Daigongen (金毘羅大権現) is enshrined is Matsuoji Temple (松尾寺) of the Koyasan Shingon sect.
Speaking of Matsuo Temple, Matsuodera (松尾寺) Fudarakusen (補陀落山) in Yamato Koriyama, Nara Prefecture, where the tomb of Soga no Irika (蘇我入鹿) is located.
Strangely enough, "Miyayama (宮山)", in Misaki-Cho, Okayama Prefecture, is exactly located at the point that forms 2:1:√3 with the two temples of Matsuo (松尾寺).
I don't think the relation of this figure is a coincidence. It seems to have a deep meaning.
