In Kojiki (The Records of Ancient Matters), he was considered as Kagurohime, but since Kagurohime was a great-granddaughter of his real older brother, YAMATO Takeru no Mikoto, this was biologically impossible (it is actually described in Nihonshoki [the oldest chronicles of Japan] that she became the empress to Emperor Ojin, and his name is repeated in Kojiki, too).
古事記では迦具漏比売とされるが、彼女は実兄日本武尊の曾孫に当たり、生物学的に不可能である（現に、日本書紀では応神天皇の后となっているし、古事記でも彼の名前の重複が認められる）ことから誤記と思われる。
