Princess Iwa

[citation needed] No firm dates can be assigned to Emperor Nintoku's life or reign, nor to that of his first wife.

[citation needed] Princess Iwa's poetry, or poems attributed to her, are included in the Kojiki, the Nihon Shoki and the Man'yōshū.

Poems which Iwa-no hime is said to have exchanged with her husband are related in the Kojiki and in the Nihon Shoki.

[2] 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.

[7] Both kofun-type Imperial tombs are characterized by a keyhole-shaped island located within a wide, water-filled moat.
