崇神天皇
An anecdote concerning Emperor Sujin relates that Amaterasu (via the Yata-no-Kagami and the Kusanagi sword) and Yamato-no-Ōkunitama, the tutelary deity of Yamato, were originally worshiped in the great hall of the imperial palace. When a series of plagues broke out during 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-no-Ōkunitama to another daughter, Nunakiirihime. 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. When the god was offered proper worship as per his demands, the epidemic ceased.
