The intermediate part of Kojiki (The Records of Ancient Matters) contains a scene where Yamato Takeru (no Mikoto) encountered a white boar on the way to beating down the god of Mt. Ibuki, and did 'kotoage' ritual by saying as follows; 'This should be an emissary of the god. Then, I will kill it on my way back not now.'
