[4][b] Although details change in various records, her parents are described as a deity (her father), and a daughter of an influential person in the Yamato Province (her mother).

[7][4] According to the Kojiki, when Kamu-yamato-Iwarebiko (Emperor Jimmu) was searching for a wife, he was told about a woman named Seya-datara-hime (勢夜陀多良比売) who bore a daughter after she was impregnated by Ōmono-nushi (the ‘Great Diety of Miwa’).

[11][12] Likewise, the main narrative in the third and fourth volumes of Nihon Shoki refers to her as the daughter of Kotoshiro-nushi rather than Ōmono-nushi.

[15] According to the Nihon Shoki and other sources, Iwarehiko (later Emperor Jimmu) left the Land of Himuka and made an expedition to the east, and after many battles, established his government in the Yamato region.

Iwarehiko built the Palace of Kashiwara in modern-day Kashihara at the foot of Mount Unebi and ascended to the throne as the first Emperor.

Although there are differences in details, the Nihon Shoki and Kojiki describe a succession struggle that occurred among his children after his death.

[25] There is a theory which interprets that by marrying "the child of god" (Hime-tatara-isuzu-hime) as his principal wife, Jimmu, the first Emperor, made use of her in order to legitimize his regime.

Finally, there is also an interpretation that this story works to explain how Emperor Jimmu's forces had acquired iron-manufacturing technology.

[i] Since there are some historical records in which "-耳神" (literally: god of ears) is added to his name, there is a theory that this suggests Mizukuhi is an object of worship as a divine being.

[3][29][j] In the Edo period, Motoori Norinaga, a scholar of Kokugaku, interpreted this "mizo (groove)" to refer to a toilet built over a stream of water, and this has become a prevailing view.

[11][19][Shoki 1][Kojiki 2] Motoori Norinaga identifies Seya (勢夜) as Seno village of Heguri-gun in Yamato Province (Sangō Town of Ikoma County in Nara Prefecture).

[39][o] In other words, the fact that Emperor Jimmu took Hime-tatara-isuzu-hime (= Hime-tatara-isuke-yori-hime = Hoto-tatara-isusuki-hime) as his wife is interpreted as an indication that the royal family controlled the iron and steel industry.

[39] Yutaka Yoshino (Japan Literature Association) states that the name "Hoto-tatara-isuzu-hime" refers to a priestess who served the god of molten ore and the blast furnace.

[40] Motoori Norinaga and other early modern Kokugaku scholars did not interpret the word "tatara" in Hime-tatara-isuzu-hime to mean a bellows.

[40] In their view, the word tatara is a slang term used by blacksmiths and is dismissed from its ties to steelmaking as it is unsuitable for the name of a noble empress.
