Another theory was that it was derived from Susa-jinja Shrine in Izumo (the present-day Susa-jinja Shrine in Izumo City, Shimane Prefecture) (Susano was created by deifying the head of Susa-go), or that it was from the king of iron sand or the chief of O County.
また、出雲の須佐神社(出雲市)（現在の島根県出雲市須佐神社(出雲市)）に因むとする説（スサノオは須佐郷の族長を神格化したものとする）、州砂(砂鉄)の王という説から、意宇郡(おうのこおり)の首長とする説などがある。
