How the young prince receives the name Yamato-takeru

An alarming act at home leads to a western mission carried out through disguise and deception.

A command interpreted violently

The Kojiki introduces the young prince Wo-usu through a disturbing exchange with his father. Asked to make his elder brother attend the royal meals, he kills and dismembers him instead. When the father discovers what has happened, he is alarmed by his son's violence and sends him west against two Kumaso leaders who refuse submission.

The prince obtains garments from his aunt Yamato-hime, conceals a weapon, and travels to the enemies' dwelling. He finds it heavily guarded and waits until a celebration offers another way inside. The mission is already connected to the court's fear of its own agent. His capacity for force is useful, but it is not presented as uncomplicated virtue.

A new name from a dying opponent

Arranging his hair and wearing his aunt's clothing, the prince appears among the women at the feast. The two leaders are delighted and seat him between them. At the height of the celebration he attacks the elder. The younger runs away, but the prince overtakes and wounds him.

Before the final blow, the defeated man asks who he is. Hearing his royal identity, he acknowledges that the prince surpasses the strongest men of the west and grants him the name Yamato-takeru. The prince then kills him. The name therefore comes from an enemy's recognition, framed by lethal coercion, rather than from a peaceful award at court.

Friendship becomes another weapon

A following episode places Yamato-takeru in Izumo. He befriends a local champion while secretly preparing a wooden substitute for a sword. During a shared bath he takes the other man's real weapon and proposes an exchange. When he then challenges the man to fight, the opponent cannot draw an effective blade and is killed. Yamato-takeru celebrates the deception in song and returns to report.

These western exploits show repeated success through manipulated expectations: hospitality admits a disguised attacker, and apparent friendship makes a fraudulent exchange possible. The court narrator treats the targets as opponents of its order. A modern account can preserve that viewpoint without adopting its classifications as neutral descriptions of historical peoples or making treachery disappear from the hero's methods.
