三輪山
Book V in the adds the following quaint episode. Suijin's aunt, the aforementioned Yamato-to-to-hi-momoso-hime, was later appointed the consort or wife of Ōmononushi (Mount Miwa). The kami however, would only appear to her at night, and the princess pleaded to reveal his true form. The kami warned her not to be shocked, and agreed to show himself inside her comb box () or toiletry case. The next day she opened the box and discovered a magnificent snake inside. She shrieked out in surprise, whereby the deity transformed into human form, promised her payback for shaming him so, and took off to Mount Mimoro (Mount Miwa). The princess was so distraught at this, that she flopped herself on the seat stabbed herself in the pudenda with chopsticks, which ensued in her death. She is supposedly buried at one of the six mounds near Mount Miwa, the mound. The 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.
