[7][8] Omonoimi no Kami is considered possibly identical to Toyouke-hime[a][9] who is also worshipped at the Warabioka subshrine.

[7] Omonoimi no Kami is primarily associated with industrial growth and is also enshrined in other places in the Tōhoku region, including Chōkai gassan ryōsho-gu [simple; ja].

[5] The repeated destruction of the main shrine means archaeological evidence is difficult to find.

[7] Early mentions of the shrine include the Engishiki Jinmyocho where it is listed as a Myojin Taisha, a very highly ranked shrine and mentions in the Nihon Sandai Jitsuroku whjere an oracle foretold the Imperial Army's defeat in 878 and 879.

At that point a massive eruption happened and dark muddy water flowed down the rivers which were dammed by dead fish.

[17] Omonoimi no Kami is known to have received the rank of Shōichii in the reign of Emperor Yōmei.

[5] The shrine has a festival every year on July 14 called Hi-awase shinji (火合せ神事).

[7] It is said in local tradition that the legendary Buddhist monk En no Gyōja founded the shrine.

[5] There are three torii gates and the movie Rurouni Kenshin: The Legend Ends was filmed there.
