Since Hikawa-jinja Shrine is an old establishment listed in the "the Engishiki" (an ancient book for codes and procedures on national rites and prayers) and the main god of Hikawa-jinja Shrine became Susanoo (in other words, the original main god Arahabaki became the guest god) only because of political reasons of the Edo bakufu (Japanese feudal government headed by a shogun), the story on the link between Izumo and Hikawa may be taken as part of the process of Emishi (including Toraijin [people from overseas, especially from China and Korea, who settled in early Japan and introduced Continental culture to the Japanese]) control by the Yamato Court.
氷川神社が延喜式に掲載されている古社であり、かつ、氷川神社の主祭神がスサノオになった（＝元々主祭神であったアラハバキ神が客人神になった）のは江戸幕府の政治的意図によるものであることからすれば、出雲と氷川の繋がりの話は、大和朝廷による蝦夷（含、渡来人）支配の一過程であると捉えたほうがよさそうである。
