When a series of plagues broke out during Emperor Sujin's reign, he "dreaded [...] the power of these Gods, and did not feel secure in their dwelling together."

He thus entrusted the mirror and the sword to his daughter Toyosukiirihime, who brought them to the village of Kasanuhi, and delegated the worship of Yamato Okunitama to another daughter, Nunaki-iri-hime [ja],[1][2]but her health began to fail shortly afterward.

It is recorded that Nunakiiri-hime became emaciated after losing all of her hair, which rendered her unable to perform her duties.

[4] When the pestilence showed no sign of abating, he then performed divination, which revealed the plague to have been caused by Ōmononushi, the god of Mount Miwa.

[7] In 965, Emperor Murakami ordered that Imperial messengers were sent to report important events to the guardian kami of Japan.
