In-giyō's age at death of seventy-eight and his burial at Naga-ye near Wega in Kafuchi place him in the same Kafuchi (modern Osaka area) burial-corridor as Chiū-ai, Ri-chiu, and the other late-fifth-century emperors. The clustering is geographically significant: the keyhole-tomb mound-builders of the period were concentrating dynastic monuments along the Osaka Bay coastal plain, near the political center of the Yamato polity but visible from any sea-approach. By the time the Kojiki was compiled in 712, the political center had shifted to Nara and then briefly to Otsu and Fujiwara, but the great kofun cluster in modern Osaka remained as the most visible monument to the dynasty's fifth-century apex. The mausoleums are still there, still un-excavated, still maintained by the Imperial Household Agency.Kojiki CXI (In-giyō's Burial)
