The Kojiki gives Ninigi one further episode beyond the descent his own deity record narrates: when Konohanasakuya-hime tells him she is pregnant after their single night together, Ninigi doubts the child can be his and says so. Stung by the accusation, she shuts herself into a doorless birthing hut, sets it alight, and declares that if the children are truly his they will come to no harm in the flames. She bears three sons unhurt inside the burning hut, Hoderi, Hosuseri and Hoori, each carrying fire in his name for the ordeal of his birth. Hoori is the youngest of the three, and it is through him and his son Ugayafukiaezu that the line the Kojiki traces continues down to Emperor Jimmu, so the doubt Ninigi voiced becomes the origin of the fire that proves his own line legitimate.

SymbolHis descent to earth carried the three sacred imperial regalia, the mirror, the sword and the curved jewel, still central symbols of the Japanese imperial line. 1 Canonical ReferenceThe Kojiki explains human mortality itself as a consequence of Ninigi's choice: when he takes Konohanasakuya-hime as his bride but sends her elder sister Iwanaga-hime, whose name means everlasting rock, back to their father in shame, the affronted father withdraws the eternal life he had attached to both daughters, and the imperial line becomes mortal from that point on. 1 Position Profile

FoundedTradition holds his grandmother Amaterasu sent him down from the heavens to Takachiho in Hyuga to rule the earthly realm, carrying with him the three Imperial Regalia, the sword, mirror and jewel, a descent known as tenson korin from which the imperial house of Japan traditionally traces its line. 1 Practice
Mode of TransmissionThe two earliest written compilations of the myth, the Kojiki of 712 and the Nihon Shoki of 720, preserve differing versions of his descent to Takachiho, reflecting an oral court tradition that had not yet settled into one fixed telling by the time either was written. 1 LineageGrandson of Amaterasu; husband of Konohanasakuya-hime, whom he doubted when she announced her pregnancy; father, born unharmed from her trial by fire, of Hoderi, Hosuseri and Hoori; ancestor, through Hoori and Ugayafukiaezu, of Emperor Jimmu 1 Attributions

Ninigi's Descent: Two Mountains Named Takachiho
The Kojiki's account of Ninigi's descent from heaven, the Tenson Korin, names Takachiho as the peak where he arrived carrying the imperial regalia, but Donald Philippi's standard scholarly translation and modern Japanese tradition alike leave the exact mountain genuinely unsettled rather than agreed. Two separate locations in Kyushu claim the title today: Takachiho-no-Mine, a volcanic peak within Kirishima-Kinkowan National Park where a bronze replica of a sacred spear, Ame-no-Sakahoko, stands driven into the summit rock in memory of Ninigi's own descent, and Takachiho Gorge and the town of the same name in neighboring Miyazaki Prefecture, whose own tradition claims the same event for its own mountain. Coverage of the region published in 2026 describes the Miyazaki site's claim directly while naming the Kirishima peak the more visually dramatic of the two, a description that states the rivalry as a live, ongoing feature of how the two regions each tell the story rather than a settled question with one right answer. Neither claim can be adjudicated by the Kojiki's own text, which names Takachiho without the modern administrative precision that would resolve which of two places carrying the same ancient name it originally meant, so the rival tradition is best recorded as exactly what it is: a genuine and unresolved local disagreement over where Japan's founding myth of divine descent actually happened.
Ninigi's Shrine: Kirishima Jingu Today
Ninigi carries a same-figure-other-register edge to Deity 47128, whose own record states him actively venerated in a living tradition and names Kirishima Jingu in Kagoshima Prefecture as his principal cult centre, a standing this article states as concrete present-day fact. Helen Hardacre's history of Shinto documents shrines of Kirishima Jingu's antiquity and imperial association as continuously maintained institutions rather than museum pieces, consistent with the shrine's own documented history: founded in the sixth century near the peak associated with Ninigi's descent, repeatedly destroyed by the eruptions of Mount Kirishima over the centuries, relocated in the Muromachi period, and rebuilt at its present site in 1715, where the current structure still stands. Coverage of the shrine describes it hosting more than one hundred Shinto rituals annually, with the largest observance, a drum festival, held on New Year's Day, a continuing ceremonial calendar rather than an occasional or lapsed one. That combination, an imperial-descent myth still actively marked by a working shrine with its own annual ritual calendar, is the concrete form Ninigi's actively venerated status takes today, distinct from the mythic descent narrative itself, which this record already carries on his own entity page and in the companion article on the disputed mountain.
