Ancient Japanese texts like the Kojiki and the Nihon Shoki for example mention how Yamato Takeru after his death became a white bird and in that form chose a place for his own burial.
Vanhat japanilaiset tekstit kuten Kojiki ja Nihonshoki mainitsevat esimerkiksi, kuinka Yamato Takeru muuttui kuolemansa jälkeen valkoiseksi linnuksi ja valitsi oman hautapaikkansa.
