Princess Yamato Totohi Momoso

[3][4] The Kiki, the collective name for the Kojiki and the Nihon Shoki, records that pestilence struck during the 5th year of Sujin's rule, killing half the Japanese population.

Amaterasu was moved to Kasanui village (笠縫邑) in Yamato Province (Nara), where a Himorogi altar was built out of solid stone.

The divination involved him making a trip to the plain of Kami-asaji or Kamu-asaji-ga-hara (神浅茅原), and invoking the Yaoyorozu no Kami (八百万の神, Eight Million Gods).

Sujin's aunt, Princess Yamato Totohi Momoso, daughter of the 7th Emperor, Kōrei, acted as a miko, and was possessed by a god who identified himself as Ōmononushi.

The god Ōmononushi (whom some sources to the chronicle identify with the Mount Miwa deity) spoke through the mouth of an elder princess of the imperial house named Princess Yamato Totohi Momoso (daughter of 7th emperor Emperor Kōrei and Sujin's aunt[7]) and revealed himself to be the deity residing in the borders of Yamato on Mount Miwa, and promised to bring end to chaos if he were properly worshipped.

Sujin's aunt Princess Yamato Totohi Momoso, who was skilled at clairvoyance, interpreted this to mean that Take-hani-yasu-hiko (Ōhiko's half brother) was plotting an insurrection.

Princess Yamato Totohi Momoso pieced it together from overhearing news that Take-hani-yasu-hiko's wife (Ata-bime) came to Mount Amanokaguya (天香久山), and took a clump of earth in the corner of her neckerchief.

[a] Emperor Sujin gathered his generals in a meeting upon hearing the news, but the couple had already mustered troops to the west who were ready to attack the capital.

The Emperor responded by sending an army under the command of general Isaseri-hiko no Mikoto to fight a battle that ended with a decisive Imperial victory.

[8] The Kojiki version of this myth describes a union between a woman from the Miwa clan and Ōmononushi, resulting in the birth of an early Yamato king.

Scholars note that this is a clear effort to strengthen Yamato authority by identifying and linking their lineage to the established worship surrounding Mount Miwa.
