Yamatotakeru who ventured to conquer western regions, as described in Historical Events, seemed to bear multifaceted characters, because a multitude of images were reflected on him. Especially his ferocity was a clear message that he could not succeed to his father, the emperor. Also it could be analysed in terms of a means to suppress those who disobeyed him. The ferocity had thus played an absolutely instrumental role in expanding the power of the Yamato regime. And his brutality appeared to show a role of punisher as he punished his brother who committed a grave sin to his father. In the long run, while he failed to succeed to the supreme power because of such brutality, later his son benefitted completely from his struggle for power. On the other hand, during his conquest of the west, femininity was manifested. It indicated a lot of courtesan- or female-shaman-like characters and implied a superstitious sense. He used alcohol or tricks to control rivals, and the red color was highlighted in the conquest of Izmotakeru. Marks of Ssanow could be traced from these. And some differences between Historical Events and Japanese Chronology are also discussed in this study.
