It seems that the Katsurakisitoriniimasu Amenohaikazuchi no Mikoto-jinja shrine was a worship space or something like a sato-miya shrine (shrine built in a village area as a worship space for another shrine in a mountain) belonging to the Futakami-jinja shrine on the top of the mountain.
山頂の二上神社の遥拝所もしくは里宮的な存在であったとみられる。
