Biography No firm dates can be assigned to Emperor Nintoku's life or reign, nor to that of his first wife. Nintoku is considered to have ruled the country during the late-fourth century and early-fifth century, but there is a paucity of information about him. There is insufficient material available for further verification and study.

Princess Iwa's poetry, or poems attributed to her, are included in the Kojiki, the Nihon Shoki and the Man'yōshū. Her tomb is said to be located in Nara Prefecture.

Literature Poems which Iwa-no hime is said to have exchanged with her husband are related in the Kojiki and in the Nihon Shoki. Nintoku is reported to have suffered the resentment of the Iwa-no hime during a period in which he stopped the collection of taxes, which meant that even ordinary repairs to the palace were also deferred.

Poetry attributed to Iwa is collected in the Man'yōshū, Some modern scholars, however, advise a healthy skepticism in these difficult to verify attributions.

Burial mound tomb The Imperial tomb of Iwa no hime no Mikoto is said to be located in Saki-chō in the city of Nara. Both kofun-type Imperial tombs are characterized by a keyhole-shaped island located within a wide, water-filled moat.
