Both "Kojiki" and "Nihonshoki" mention a story where Yamatotakeru no Mikoto entered Mt. Ibuki in Yamato Province (present-day Nara Prefecture) without the Kusanagi no Tsurugi (Sword of Kusanagi) in 110, in order to defeat the god of Mt. Ibuki (this god is thought to have been a local magnate) with his bare hands.
『記紀』には、景行天皇四十年（110年）に日本武尊が、大和国（現在の奈良県）の息吹山の神（豪族の長?）を素手で倒そうと、草薙剣を持たずに、素手で山に入ったことが記されている。
