Princess Iwa
, sometimes known as , was a poet and the Empress consort of Emperor Nintoku, who was the 16th Emperor of Japan, according to the traditional order of succession. She was a descendant of Emperor Kōgen. 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, the oldest existing collection of Japanese poetry believed to  have been collected by Ōtomo no Yakamochi (大伴 家持). In her four songs she expressed love and longing for her husband. 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.
