仁德天皇
Some of the earliest written records of hitobashira can be found in the "Nihon Shoki (The Chronicles of Japan)". One story centered on Emperor Nintoku (323 A.D.) discusses the overflowing of the Kitakawa and Mamuta Rivers. Protection against the torrent was beyond the ability of the stricken populace. The Emperor had a divine revelation in his dream to the effect that there was a person named Kowakubi in the province of Musashi and a person called Koromono-ko in the province of Kawachi. If they should be sacrificed to deities of the two rivers respectively, then the construction of embankments would be easily achieved. Kowakubi was subsequently thrown into the torrent of the Kitakawa river, with a prayer offered to the deity of river. After the sacrifice the embankment was constructed, Koromono-ko however escaped being sacrificed.
