Two sisters carry different promises
After descending from heaven, Ninigi meets Konohanasakuya at Cape Kasasa and asks to marry her. She refers the decision to her father, the mountain deity. He sends both her and her elder sister Iwanagahime, accompanied by gifts. Ninigi rejects the elder sister because he finds her appearance displeasing and keeps the younger.
Their father explains the consequence. The sisters had been offered together so that the heavenly descendants could possess the endurance of rock as well as the flourishing beauty of blossoms. By returning the rock-associated sister, Ninigi has forfeited lasting durability. The text uses this rejected marriage to account for the limited lives of later sovereigns, despite their divine ancestry.

The pregnancy becomes a dispute
Konohanasakuya soon announces that she is pregnant and that the birth is approaching. Ninigi questions whether a single night's union could have produced his child and suspects an earthly deity instead. She responds by making the safe outcome of delivery a test of the child's heavenly paternity.
She constructs a birth house without an ordinary exit, seals herself inside, and sets it on fire when labor begins. Three sons are born as the flames progress. Their names connect them with stages or aspects of fire. The narrative presents their survival as the answer to Ninigi's accusation. It does not describe the accusation as verified, nor provide an independent reason to doubt her earlier statement.

A claim proven at bodily cost
The episode closes by identifying the children and, for one, an ancestral affiliation. These births continue the genealogy that will connect heavenly descent to later rulers. Their successful outcome answers an immediate dispute while the previous rejection of Iwanagahime explains why that dynasty remains mortal.
The two scenes should be kept together without making them identical. In one, Ninigi's preference narrows what his descendants can inherit; in the other, his suspicion places his wife under pressure to demonstrate legitimacy. The burning house is an extraordinary event within a mythic genealogy, not an example of safe childbirth or a practice to imitate. Its force lies in the contrast between a father's questioned claim and the mother's dangerous act that secures it.
